"decking"

What used to be the site of the Cannon Brewery, dating back to the 1670s, and the home of London’s largest brewery, is now a modular arrangement of 198 apartments with a selection of one, two and three bedroom flats and five town houses built around a landscaped courtyard. The project was designed by architects Hamilton Associates and completed in 2022.Literally a stone’s throw from our Studio in Clerkenwell, London, this was a remediation project, where the existing timber was removed and replaced with our BalcaSmart Aluminium system, in order to make sure the building complied with new fire regulations. The rear of the building also features our TerraSmart Pedestal system.Our aluminium decking system is non-combustible, achieves Euroclass A2-s1,d0 to EN 13501-1:2018, is ideal for all steel, bolt-on and cantilever balconies, and most importantly ensures the safety of all residents. This is what futureproofing is all about.

Cygnet Hospital, a new state of the art medical campus based in Maidstone required a waterproofing membrane for the newly installed concrete and metal decks. Proteus Waterproofing applied their Cold Melt® membrane, to provide a seamless leak protection to the inverted roof, that was then finished with Proteus Waterproofing’s Pro-Living® Green Roof. High Performance WaterproofingFirstly, the metal deck for the main roof was prepared and overlaid with Pro-Vapour Control SA, a self-adhesive bituminous waterproofing membrane that forms a barrier against vapour and gases, ready for the Proteus Pro-Therm PIR Insulation and Cold Melt® waterproofing installations.Proteus Pro-Therm PIR is stable, rot proof and will remain effective as an insulation system for the lifetime of the waterproofing covering, making it suitable for new builds. Cold Melt® waterproofing was then overlaid to the main roof and upstands. The exposed areas were covered with Cold Melt® UV Top Coat, making the waterproofing UV stable. Cold Melt® provides a seamless leak protection and is cold applied, therefore removing the risk of fire. The roof was completed with a Pro-Living® Green Roof providing ecological benefits for the building. Health and SafetyWhen working on occupied buildings, safety is of utmost importance. Proteus Waterproofing’s Cold Melt® system is cold applied and low odour, therefore meeting all necessary health and safety requirements. Cold Melt® is quick, simple and safe to apply allowing the Proteus Approved Contractor to successfully complete the project to a high standard within a short time frame, whilst ensuring the planned building works continued to run on schedule.Long Term PerformanceIncorporating recycled rubber crumb and organically grown products, Cold Melt® creates an elastomeric, seamless, cold applied waterproofing membrane. Cold Melt® system can include inverted roof insulation and, with or without insulation, can be designed as a paved, ballasted, green or brown roof. The membrane is made in the UK, does not become brittle with age and is BBA Certified to last the life of the structure.

THE PROJECTThe village of Comrie is located towards the western edge of the Perth & Kinross Council area, approximately 40 kilometres west of Perth in Scotland. The waterproofing system used to cover the buried water tank at Comrie Distribution Service Reservoir (DSR) was many years old and had failed. As part of the ongoing Scottish Water SR21 framework, Fosroc and The Fraser Bruce Group have developed a wide range of solutions for waterproofing water tanks that have been proposed and agreed by both Morrison Construction and Scottish Water. This project involved removing the soil overburden and the existing waterproofing system, before mechanically preparing the deck and applying sheet membrane.THE SOLUTIONOnce the overburden and existing waterproofing were removed it was apparent that there was severe ponding on the tank roof. The decision was taken to prepare the deck and apply an external self-leveler to prevent the ponding of water. The perimeter and upstand detailing was carried out before Fosroc’s self-adhesive sheet membrane Proofex 3000 was applied to the primed, horizontal surface. The surface was then protected with Proofex Sheetdrain 80, a drainage and protection membrane. After the membrane was laid, the access hatch upstands received two coats of Nitocote CM210 before more Proofex 3000 was applied and terminated just below the height of the new overburden. The access hatches were then sealed in place with Nitoseal MS600.THE BENEFITSProofex 3000 membrane, which is cold applied and comes in 1m x 20m rolls, is self-adhesive, thereby reducing the amount of product and application time. The applicator was able to cover large areas in far less time. The membrane is made from cross laminated HDPE film to protect against damage, while still being sufficiently flexible for detailing around corners. It is resistant to ground water, soluble sulfates and chlorides, offering robust protection from aggressive ground salts. Its use with Sheetdrain achieved a high quality, reliable installation compliant with EN 13707:2004. By combining the use of Nitocote CM210 and Proofex 3000, Fosroc were able to provide solutions for both exposed and buried areas of the tank with no compatibility issues between the products.

HMS Belfast, the most significant surviving Royal Navy warship from the Second World War, has been equipped with L1 category fire systems from Advanced. The decommissioned destroyer, which is permanently moored as a museum ship on the River Thames in London, was fitted with eight-loop and two-loop MxPro 5 fire panels, plus a TouchControl touchscreen remote control terminal and repeater.Fitted on behalf of the Imperial War Museum, which owns and operates the historic vessel, the new fire system covers six of the warship’s nine decks, as well as its on-shore visitor pavilion.Advanced’s long-standing partner, ADI Global, was responsible for the supply of the fire alarm control panels for the project at HMS Belfast, while facilities services company Atalian Servest was responsible for the installation, commissioning and networking of the fire panels in accordance with BS 5839. The panels were integrated with around 700 Apollo XP95 detectors and interfaced with VESDA aspirating smoke detection.

A bespoke Gatic CastSlot system was installed as part of the redevelopment of the riverside stand for Craven Cottage, home to Fulham FC. The project, which began in July 2021, incorporates Gatic CastSlot Treadsafe, which was chosen to drain away any excess surface water from the seating/standing areas along the deck of the stand. It was installed by main contractors Buckingham Group.The unobtrusive profile of CastSlot sits neatly within concrete, asphalt, and block surface finishes and features an electro painted ductile iron throat section. This is securely fixed to the galvanised steel channel body to provide an exceptionally robust yet discreet drainage system.The treadsafe option was chosen for this project. Treadsafe is available for areas where there is regular foot traffic and is available with a 10mm or 30mm opening—ideal for stadium standing and seating areas.Bespoke access boxes were also created for the new stand, and channel throat depths were also extended for level changes, allowing a constant invert within the channel.

One Tower Bridge is the home for a new 900-seat theatre built for the London Theatre Company on the South side of Tower Bridge called the Bridge Theatre. The theatre is one of the largest to be built in London in the past 100 years.To protect the residential accommodation that wraps around the theatre the acoustic consultant specified that the theatre be built on a 200 mm concrete floating slab supported on springs (Stravifloor Deck). The structural engineers specified that the floating slab must spread the loadings of the theatre structure as much as possible to the supporting structure beneath.CDM Stravitec’s in-house structural engineers used finite element analysis to optimise the load spread of the floating slab whilst retaining the acoustic requirements. The optimised design incorporated 4,300 springs with higher concentrations of springs where the imposed loads were greatest.Reinforcement density was also increased in the higher loaded areas to optimise the load spread characteristics of the slab. The floating slab was installed within a very tight timeframe of 3 weeks in order to comply with the project build programme.

Rush Green Primary School, LondonClient: London Borough of Barking & DagenhamProduct: The Coniston Wall Mounted CanopySize: 16.3m x 2.2mFrame Colour: Hipca WhiteInstallation Date: June 2023Brief Having worked with the London Borough of Barking and Dagenham before on a number of projects, they contacted us again regarding their most recent project at Rush Green Primary School. The school which is located in Dagenham were having works completed which included a single storey extension, internal alterations, and refurbishment. As part of the works, they required a wall mounted canopy in their quad courtyard area to provide shade and shelter all year round.Proposal As requested, we provided an estimate for a Coniston Wall Mounted Canopy with a length of 16.3 metres and a projection of 2.2 metres. Because the Coniston is mounted to a wall, it requires a suitable wall to fix to; the building at Rush Green Primary School was a block construction which was covered with render, which is one of the many ideal wall constructions for the Coniston’s requirements. In the case where a wall may not have a suitable construction for a wall mounted canopy, we can supply the Coniston as a free-standing canopy with rear posts. Alternatively, we also have a number of free standing canopies that are similar in appearance to the Coniston which are the Grange Free Standing Canopy and for those with lower budgets, the Grange Junior Free Standing Canopy.Solution Upon comparing our canopy quotation to two other companies, an order was placed for our Coniston Wall Mounted Canopy in May 2023.At the pre-site stage, there was a number of points to be discussed outside of the usual specifics which were:Foundations: Unless otherwise stated, foundations are included in all our canopy quotations. The flooring in at Rush Green Primary School featured raised decking, so we needed to investigate the area underneath the decking to check it was suitable for our foundations and they were.Access and Obstructions: The quad area features a pond which could have made an obstruction however, it was agreed that the pond would be covered over with strong boards so we could work over it.The canopy was installed at the start of June 2023 as scheduled with no problems along the way.If you have a similar project in mind, contact us today to request a free estimate or discuss a bespoke canopy with us.

Based at Manchester’s waterfront in Salford Quays, MediaCityUK Studio Block is the largest media development in the UK and will become centre for the world’s leading creative and digital businesses. The BBC is one of mediacity:uk’s anchor tenants and from 2011 it will be home to five BBC departments including two TV channels and two radio stations; three of them are Radio Five Live, BBC Sport and CBeebies.Many of the studios in the main Studio Block have Stravifloor Jackup jack-up concrete slabs to optimise the sound insulation between noise producing and noise sensitive spaces. These floating floors in combination with the structure of the studios being isolated off Stravibase SEB simple elastomer bearings delivering high performance box-in-box constructions.The TV studios built off the upper floors were built using a heavily damped concrete construction supported at 600mm centres using Stravifloor Deck isolation rails. In these studios the structure of the studios was built off the floating floors to create the box-in-box whilst providing very stable conditions for the TV cameras.

Garratt Lane in Tooting is located in the South East of London, close to the Northern Line on the London Underground, making it a residential building perfect for commuters.Works started on Garratt Lane towards the end of June 2014, where we supplied approximately 2,350 m2 of Soundis cradle & batten acoustic flooring to provide a deep service void and a level floor on the un-even concrete structural deck. Our Cradle and Risers are manufactured from 100% recycled materials assisting to the sustainability targets of projects. The extremely un-even sub-floor throughout the premises combined with project specific requirements of a deep service void for Under Floor Heating soon meant the Soundis Cradle System was the only solution in maintaining a 125mm finish floor height throughout the project.The quality of installation by our installation partner UK Acoustic Systems was made clear upon the release of the acoustic flooring testing results as noted below. The average reduction and improvement of Impact noise was 22dB, with Airborne performance averaging 56dB, which is significantly higher than ADE and RD regulations.

A £5m renovation scheme in Warrington has been presented with the “Best Change of Use to Existing Building” regional award by LABC (Local Authority Building Control) and Warrington Borough Council.The scheme required the conversion of a former office building, Kings Court, in Central Warrington, into 32 luxury flats, comprising of a mix of one and two bedroom apartments, arranged over three floors of accommodation. These flats are situated above retail units and restaurants. The renovation included a further two exclusive duplex penthouses for Phase 2.As part of the renovation, Main Contractor Emerald Bay Construction required an acoustic flooring solution to meet Approved Document ‘E’ Building Regulations and therefore provide overall resident comfort, in terms of Sound Insulation between separating floors. As the building structural floor was primarily concrete, Soundis put forward a solution that involved 2,072 m2 of Soundis ChipPanel 28 to help with Impact Noise. This shallow deck floating floor is ideal for concrete floors where Airborne Noise is not an issue but Impact Noise Attenuation needs to exceed the requirements of current Building Regulations.

Whitethorn Village is an attractive residential scheme positioned adjacent to the centre of Naas. The contemporary development led by Cairn Homes PLC includes a mix of spacious family homes and two apartment buildings. These comfortable, sustainable residences offer the very best in terms of quality and energy efficiency.Developer Cairn Homes collaborated with Horizon Offsite to deliver the impressive 5-storey residential blocks in Whitethorn Village, benefiting from off-site fabrication, accuracy, and rapid completion within a tightly controlled cost plan.The apartments were constructed using an offsite fabricated light gauge steel (LGS) structural system. The external LGS wall panels and floor decking used in this system incorporated a number of Partel’s low carbon building envelope solutions. This included the advanced fire rated components EXOPERM MONO DURO 200 breather membrane and ECHOSEAL ALU FR airtight and windtight tape, the multi-purpose adhesive VERBOND, and also the phA Class Passive House Certified components IZOPERM PLUS vapour control layer and VARA SEAL smart airtight tape.

Non-Conductive, Anti-Slip Flooring and Walkways | Case StudyArena Events Group chose Dura Composites to supply the tiered structure stadium decking for the seating and platform areas, manufactured from our high quality and corrosion-resistant Glass Reinforced Polymer (GRP) Dura Slab 40 and 20 products which provided an anti-slip, fire-tested and load-tested alternative to the Buffalo® Board and traditional plywood used previously. Dura Composites’ ability to be able to meet a range of stringent test requirements including flare resistance tests and FEA analysis made us the ideal choice for this high profile project which not only allows for future changes to seating configurations, but also improves access to amenities on the concourse. The two types of Dura Slab used on this project are precision engineered GRP structural flooring systems that provide an incredible strength to weight ratio. High strength fibreglass composite is pultruded in one mass to produce a consistent quality flooring structure that is also non-corrosive, chemically resistant – and has an anti-slip walking surface.

Manchester’s iconic Midland Hotel sits in the heart of the city centre and has been a well-loved retreat for visitors since opening its doors in 1903. Following decades of service to the city, the hotel had started to show signs of its age, with multiple areas of water ingress across the site that needed to be addressed, to preserve the building for years to come. It was essential for the hotel to remain fully operational during the roofing refurbishment, with minimal disruption to its customers.The original single-ply system had failed across the courtyard and atrium roofs, leading to the insulation becoming fully saturated with water. The metal deck’s structural integrity had also been compromised and a structural engineer was appointed to review the extent of the damage, to confirm the area as condemned and in need of immediate replacement.A bespoke Garland UK specification was designed to upgrade the insulation and U-Value of the hotel to comply with current regulations, remove ponding water on the roof systems with a new tapered insulation design and provide peace of mind to the building owners with a 25-year Garland Single-Point Guarantee.

11 Freebournes RoadBauder reinforced bituminous waterproofing system with BauderSOLAR FSynopsisA large derelict warehouse located in Witham has undergone major renovation to transform it into a storage centre for Essex County Council that will assist its services and benefit the local community. The refurbishment works were designed and project managed by Lambert Smith Hampton on behalf of the client, who wanted the building to act as a benchmark for sustainability with the roof playing an integral part in achieving this through the addition of solar panels.Bauder Building BoardProject Name:11 Freebournes RoadLocation:Witham, EssexRoof Size:5,200m²Client:Essex County CouncilProject Manager:Lambert Smith HamptonApproved Contractor:Acclaim ContractsPV Installer:CJ SolarEnvironmental focus:Solar PVThe specificationWorking closely with the client, Bauder performed a comprehensive roof evaluation survey to identify the full extent of water ingress being experienced and to confirm the suitability of adding solar. The bespoke survey report highlighted that the roof needed to be stripped back to its original deck, before being waterproofed with over 5,200m2 of Bauder’s reinforced bitumen system by Acclaim Contracts. 588 solar PV modules were then fitted onto the roof by electrical installer CJ Solar, enabling the client to generate at least 134.70 Megawatt Hours of solar power each year. Products appliedBauderSOLAR FIntegrated photovoltaic system, where the modules and the substructure are combined to form a single unit, which is secured to the roof without any penetration of the waterproofing or roof deck. System installedReinforced Bitumen Membrane System1 Reinforced bitumen membraneTorch applied, elastomeric bitumen capping sheet2 BauderPIR M 60Rigid urethane foam insulation faced on both sides with aluminium foil.3 BauderPIR FA-TETorch applied air and vapour control layerAdvocacyJulian Sanchez, Commissioning Delivery Manager for Essex County Council: “We actively look for opportunities to implement renewable energy and knew that this storage facility lent itself well to PV retrofit. Our system selection process involved the due diligence you would expect from a local authority and we decided to go with Bauder because of its comprehensive system portfolio that meant we could have a single source supply and all-inclusive guarantee; giving us complete confidence in the roof’s performance.”

Our purposeOn behalf of Amye Defence Services, Acclaim Contracts Ltd was commissioned to address the aging roof of the building, which was leaking despite receiving patch repairs over the past 20 years. The Ministry of Defence’s Project Allenby/Connaught demonstrates the Government’s commitment to maintaining defence estates.The £1.45bn scheme is a 35-year commitment to providing modern, high quality, fully serviced, purpose built living and working accommodation for 18,700 soldiers. It involves the new build and refurbishment of more than 550 buildings across Salisbury Plain and Aldershot, including upgrading Allenby’s Building 51, otherwise known as the Sports Pavilion.Our solutionAcclaim turned to Langley to provide all the material necessary to complete the work. After stripping the original roof to the existing plywood deck, the team fitted new treated timber around the perimeter and new uPVC fascia. The current edge trims, perimeter check kerbs, and extended flues were removed to ensure regulatory 150mm clearance was achieved once the new roof covering was installed. Langley’s HT180 attachment layer was loose-laid and nailed into place to provide appropriate protection to the timber deck while the “hot works” above were undertaken. Langley’s TA-20 Flat Roofing System was installed across the roof area, with insulation to achieve the regulatory requirement of 0.18W/m2K. SA-20 Flat Roofing Detailing System was used in fire risk areas, in line with Safe2Torch guidance. The range of Langley’s TA systems complies with Broof(t4) classification and has a Local Authority Building Control (LABC) assured accreditation. Under MOAT 31, Langley’s Parafor 30 GS (cap sheet to the TA system) achieves a ‘resistance to damage” rating of R4. It is independently certified by the BBA to deliver a life expectancy of at least 40 years, one of the longest available in the UK.Acclaim fitted Langley’s ParaFurb Refurbishment Outlets to upgrade the internal outlets where possible, cleaning and priming those where the design precluded the use of ParaFurb. We installed New Code 5 lead pipe sleeves to flues and hot pipes to a minimum 150mm above the waterproofing. In addition, Langley’s ParaTrim GRP Edge Trim was fitted to all the kerbs.“It carried great weight with us that Acclaim worked in partnership with Langley, who offers an independent insurance-backed guarantee. That is indicative of pride and confidence in its work, giving synergy with Amey. It also gives us, and our client the Ministry of Defence, that the refurbished estate at Allenby will serve and be fit for purpose for decades to come.”Will Loates, Service Delivery Area Manager, Amey

University Coventry Hospital is situated in the Walsgrave on Sowe area of Coventry and is part of the University Hospitals Coventry and Warwickshire NHS Trust. The hospital opened in 2006, replacing Walsgrave Hospital the original hospital at the site.Twinfix was approached by Principal Contractors William Gough to design, manufacture and install a walkway from the helipad on the first-floor deck to the hospital’s Accident and Emergency department. The requirement was for a robust walkway that was structurally sufficient to withstand the usual weather forces and the down draught from a helicopter in close proximity.Liaising closely with William Gough and designer Pinnegar Hayward Design, the expert team at Twinfix designed, manufactured and installed a 240 sqm free-standing mono-pitch canopy with vertical perforated side panels. This impressive canopy design included lockable double leaf gates to secure the area.The roof comprises of our Multi-Link-Panel Non-Fragile (NF) system powder coated to RAL 5010 – gentian blue and glazed with 16mm multiwall polycarbonate, and the vertical panels were powder-coated to RAL 7037 – dusty grey. As this metal does not rust in use, the walkway will keep its good looks throughout its long life.

Cambridge University, Department of Civil EngineeringBauderBLUE STORMcell with BauderSOLAR G LightSynopsisThis new build project in the centre of Cambridge combines a Sustainable urban Drainage Solution (SuDS) with vegetation and renewable energy in a warm roof construction.The client for the Department of Civil Engineering at Cambridge University, R H Partnership, identified sustainability as being a key driver in the design of the roof, but also sought a single source supplier that could provide a guarantee for both workmanship and products. Bauder’s systems range encompasses products to meet all the sustainability objectives, and with our network of approved contractors carrying out the installation, we could offer the comprehensive guarantee that was required.Bauder Building BoardProject:Cambridge University Department of Engineering​Location:CambridgeRoof Area:1610m²Client:University of CambridgeSpecifier:RH Partnership ArchitectsMain Contractor:SDC LimitedApproved Contractor:Voland LimitedThe specificationTo meet the sustainability criteria set out by the client, the Bauder technical team designed a roof system combining an extensive blue roof, a green roof and a solar PV array. The first and most fundamental element of the roof system though is the waterproofing. Bauder Total Green Roof System (BTGRS) was selected as it provides robust and durable waterproofing with a life span in excess of 35 years, as validated by BBA Certificate 10/4744. The Plant E cap sheet has also been tested by the FLL to ensure long term root-resistance, making it ideal for use in conjunction with the BauderSOLAR G LIGHT system. The BauderSOLAR G LIGHT system is a unique way to combine rooftop vegetation with renewable solar energy. The PV panel mounting boards are held in position using the growing medium as ballast, meaning the waterproofing is not penetrated and therefore compromised. The mounting boards incorporate a water retention feature which allows a small amount of excess rainwater to be stored for short periods of time for the various plant species to feed from. The BauderSOLAR G LIGHT system’s unique mounting system lifts the panels above the vegetation allowing the plant life to grow freely and therefore qualify a greater area of the roof as biodiverse.In addition to the BauderSOLAR G LIGHT system, a blue roof was added to the build-up. Blue roofs are sustainable drainage solutions designed to manage stormwater on a flat roof to reduce water runoff rates and ease flash flooding and standing water in built up areas. The BauderBLUE Roof System attenuates water from a flat roof over a 24-hour period via a restrictive flow outlet. Calculations are carried out to determine the rate at which the water should egress the rooftop. This is determined by the local planning authority and is often set as low as 5-8 litres per second per hectare. With these calculations, Bauder can design each flow restrictorto meet the necessary runoff rate. For the Department of Civil Engineering, the main roof area of 1455.5m² required two flow restrictors, each with flow control holes to ensure the specified discharge rate of 0.77 litres per second was achieved. The maximum depth of water the roof is designed for is the H-max. When the water level reaches H-max, it will drain via the emergency overflow pipe. These overflow pipes are set at the same height as the H-max level. On this project the H-max was calculated to be 99mm. Although an unlikely scenario, this provision for a ‘once-in-a-hundred-years’ storm event will ensure that the structural integrity of the building is always preserved.Project challengesThe roof deck was constructed using a pretensioned concrete plank roof structure. Due to the large span of these planks, the dead load weight to the roof would be restricted. This being a blue roof with green landscaping and PV (a reasonably heavy build up), presented the issue of balancing the need of the roof design and the weight restriction of the supporting structure. To add to this challenging scenario, the pretensioned deck did not provide a completely flat finish. When installing a blue roof, a flat deck with no positive or negative falls is essential, as detailed in the 2018 update of BS 6229 – Flat roofs with continuously supported flexible waterproof coverings. To overcome this onsite challenge,the final deflection of the fully loaded roof was calculated and the concrete deck was screeded to give a flat finish.The resultBauder believes this project to be one of the first of its type in the UK to bring together so many rooftop systems in one space. Project management and clear communication was paramount in order to ensure a smooth installation. The Bauder project team consisted of green roof and solar PV product managers, area technical manager, technical design team, site technicians and approved installers for the waterproofing.With all the different elements being installed, green roof and solar PV product managers worked with our technical team to design the best possible PV array configuration for optimum energy generation whilst also qualifying for the maximum biodiverse area.Bauder site technicians worked closely with Bauder approved contractors, Voland Asphalte Ltd, to ensure works were kept to schedule and that a high quality of workmanship was maintained throughout.To ensure the landscaping is maintained, irrigation was installed by Access Irrigation Ltd. The system, Permadrip Pro, is a drip line irrigation system with anti-syphon design to resist clogging and pressure regulation. Due to the specialist nature of the irrigation system, Access Irrigation Ltd provided a bespoke design service.The result of this network of expertise was a multi-faceted support service for the client, specifier, main contractor and roofing and PV installers. System installedBauder Total Green Roof System (BTGRS)1 BauderPLANT E 42Green, 5mm torch-on root-resistant capping sheet.2 BauderTEC KSA DUOA self-adhesive, elastomeric, bitumen underlayer. This underlayer was used to ensure thorough sealing of lap joints in low temperatures when the roof was installed.3 BauderPIR FA-TETissue-faced flatboard insulation faced on both sides with aluminium foil to provide efficient thermal output.4 Bauder Super AL-ETorch-on air & vapour control layer. Once installed on the concrete pretensioned plank deck, it can act as a temporary waterproofing layer, allowing internal works to be carried out immediately which was a huge advantage on this new build project.BauderSOLAR G LIGHTThis BauderSOLAR G LIGHT system was a key factor in the specification of the project to meet the sustainability criteria specified by the client. 40 PV units were installed on the main roof area on the Departmentof Engineering. The forecasted energy generated for this arrayin its first year is 9.91MWh with a CO2 saving of 5.242 tonnes/a. BauderBLUE SR-B flow restrictorThe BauderBLUE SR-B flow restrictor is designed to be used in conjunction with a standard Bauder bitumen blue roof vertical outlet DN70. The flow restrictor is comprised of four parts; baseplate, overflow pipe, baseplate inner and baseplate outer seal. The polyamide baseplate fits within the 70mm vertical outlet, with the EPDM outer seal creating a watertight fit. The HDPE Overflow slots into the central hole of the baseplate with an inner EPDM seal preventing any leaks. The baseplate has a number (1-12) of 10mm restrictive flow holes bespoke to the project. The flow restrictor has no moving parts, hugely reducing the need for maintenance or risk of failure.

As part of cultural regeneration of the Olympia Exhibition Venue, Olympia Central Hall has been demolished and the iconic structures of Olympia National and Olympia Grand, both Grade II listed buildings, are being incorporated into the site’s overall redevelopment. The West Hall Exhibition Space is being structurally strengthened to allow for a two-story music venue to be constructed above the existing exhibition hall.It is necessary to isolate the Central building, originally known as Empire Hall, from the West Hall performance space to prevent music and entertainment noise disturbance.Three massive bearing assemblies comprising solid thick steel plates holding Stravibase VHS bearings, which were pre-compressed using our patented frozen bearing technology.A small mock-up (approx. 1/3 of the size) was also constructed, and fire tested at Liege University, comfortably achieving a two-hour fire rating.Music and entertainment noise breakout from this new venue causing disturbance to residents.A custom designed Stravifloor Deck solution with rubber bearings isolating the concrete roof flab from the structure below.

In 2015, Quinn London Ltd started the refurbishment of The Market Building, in Brentford which involved the conversion of Offices to residential dwellings as a ‘Material Change of Use’ project. Soundis provided acoustic solution options for this project, in order to ensure a cost effective Value Engineering Exercise, on behalf of the Main Contractor.As the 1st floor required a deep void system due to new soil pipes and waste pipes having to be installed along the corridor within the building for kitchens and bathrooms, it was agreed to utilise Soundis Cradle & Batten System. This provided a service void for the pipes of 300mm whilst the other areas of the floor were treated with the system at 80mm FFH. The Soundis cradle & batten acoustic floor was then overlaid with a Soundis a high quality, interlocking dry screed system gypsum fibreboard.The Soundis cradle & batten floor system has been installed on the existing concrete and existing timber structural floors to provide a level floor over the un-even sub-deck. The service void provided by Soundis cradle & batten system can be used for other flooring applications, such as underfloor heating.Our Cradle and Risers are manufactured from 100% recycled materials assisting to the sustainability targets of projects.

Hotel Café Royal has just undergone a complete refurbishment and internal re-build. Part of the new complex is a state-of-the-art Spa and Gym which is located in the basement. Directly next to the hotel is Regent Street, below which runs the Bakerloo underground train line.Structure-borne noise levels from the trains were far too high to create the relaxing environment required for a top class Spa. The acoustic consultants therefore specified that all of the noise sensitive spaces must be isolated on a Stravifloor Deck concrete floating floor system.Café Royal’s 1,200 sqm Wellbeing Centre provides a personal and intimate holistic experience. It has a large lap pool and four different areas, corresponding to the four natural elements: spa/water, gym/fire, yoga/air and organic bar/earth.The spa offers a variety of Watsu hydro-experiences, a private and communal Hammam and signature Akasha treatments. Moods are enhanced by restorative music, aromas and gentle lighting. The gym has the most advanced fitness equipment, including Kinesis machines. There is a spacious aerobics studio and a private training room. Yoga, Tai-Chi and Pilates are offered in the calming area, with bespoke classes.

Lambertsson is one of Scandinavia’s largest rental companies and service providers in construction and industrial solutions. Lambertsson erects cranes and elevators for construction projects, among other activities. Shorter building times, better control over costs and smoother processes are therefore critical and beneficial to the project owners.ChallengeLambertsson has been erecting and dismantling elevators for more than a decade using wooden planks or plywood for building the elevator ramps. This method of building ramps is time consuming and resource demanding. Lambertsson needed a simple ramp solution that would make the project planning time more predictable and less time consuming when erecting the elevators. Lambertsson needed a ramp that could handle the same weight as the elevator, equivalent to a capacity of 2.1 tonnes, and without exceeding 1.3 metres from the position .SolutionIn order to meet the criteria of Lambertsson, PcP Scaffolding developed a custom solution based on the PcP OPTIMO® grating series, which is the safest choice for applications in construction, where workers are on the job. To customise a simple solution, PcP built a ramp that is able to lift the same capacity as the elevators, up to 2.1 tonnes, with a span of 80 cm. The ramp is made of aluminium decks and is very light to install.

Emmett Russell Architects has designed social housing on several infill sites on the Northern fringes of Bristol to Passivhaus standard, achieving thermal comfort solely by post-heating or post-cooling of the fresh air mass. The projects address the demand for smaller housing units.The key architectural challenge was to make efficient use of tight site limitations without overlooking neighbouring properties. The metal screened balconies allow light into the first floor flats whilst minimising views into adjacent gardens. The balcony screens step down at the sides to open up and allow longer oblique views.DeltaWing-70 was chosen to fulfil this requirement. The louvred panels were inverted to provide a privacy screen which combined the maximum screening effect in a downwards direction with minimum restriction of natural daylight.Lang+Fulton also supplied panels of PL-66×11/30×2 to form a heel-proof decking for the balconies.In addition, DeltaWing-100 was used to create secure, visually obscured storage for two bikes at each property which was integrated within the entrance canopies. Some of the properties had 2000mm wide stores with double doors, others were 900mm wide with single swing doors for vertically hung bikes.

The purpose: Water penetration into classrooms alerted theOfsted “outstanding” rated Colchester County HighSchool for Girls in Essex to a problem with its roofs.Its premises advisors, Archer Building Consultancy,turned to Langley to offer technical support for themost efficient best-value rectification, with fundingprovided by the school’s governing body, The AlphaTrust.Our solution: We carried out an in-depth roof condition report which highlightedthat the four flat asphalt and 10° pitched copper standing seamroofs urgently need repair.We advised the most efficient solution and use of resources wasto strip the copper roof back to the plywood deck and form a newwaterproof layer from our TA-30 Flat Roofing System and theasphalt roofs overlaid with TA-30 and our Liquid Roofing System.By leaving the original roof, we were able to minimise disruption.In the process, we assessed the roofs for their suitability forphotovoltaic (PV) installation, then helped address energy costs:one over a three-storey building was deemed appropriate. Finally,in partnership with Archers, we supported the detail required toapply for Salix funding to cover the supply and installation of thePV array.

The overall aesthetic appearance of this project was very important. Originally, traditional metal roofing was considered, but the client had reservations with possible noise issues and theft problems, and local planning constraints did not permit the use of traditional slate. So, Williams Roofing Contractors of Chandlers Ford were tasked in finding an alternative solution.Polyroof’s BBA approved 185 GRP System can replicate the look of metal sheeted roofing at a fraction of the weight and the price and, having no scrap value, is not prone to vandalism or theft.The contractor worked closely with the Polyroof Technical Department, the client, and the planners to produce a detailed specification for the project incorporating pre-formed trims to create a lead effect. The system was successfully installed within the project time frame and upon completion was given the usual insurance-backed 20 year guarantee from Polyroof Products Limited.Polyroof’s simulated metal finishes are achieved through the installation of Polyroof pre-formed GRP trims which are fixed to the deck or substrate prior to the application of the Polyroof waterproofing membrane. The project was nominated for the LRWA Roofing Awards due to the high level of intricate detailing that was undertaken and the care that was taken to ensure that all preformed profiles were fitted in balanced, parallel positions. The overall attention to detail by the Polyroof approved skilled operatives was first class.

St Peters Street landscapingStreet furniture | landscape seatingUnity RangeLocation: IpswichSt Peters street in Ipswich has recently been landscaped as part of the latest phase of the ‘Greener Ipswich Project.’ This renovation has aided the kickstart of green spaces across the town as well as helping to create a lively atmosphere for the public.A range of concrete seating and planters were installed here beside the bronze statue of Cardinal Thomas Wolsey, which is situated in Ipswich town centre, Suffolk. The Townscape Unity range is designed to enhance and transform any urban space while maintaining functionality. The seating and planters are robust yet easy to move if or when necessary. The products used here were the Unity 1250 seat with deck top and the Unity 1250 planter in a Yorkstone buff finish.The landscaping upgrade was prepared as part of the Towns preparation for The Coronation of King Charles III and Queen Camilla. The main theme is based on the idea of Tudor plants, particularly those with medicinal properties. Tudor gardens were designed to provide food, medicine, and a place to relax and enjoy the outdoors. The herbs that have been planted near the Wolsey statue are some of the medieval healing herbs thought to have beneficial properties for the lungs, heart, digestion, and headache.

Addenbrookes Hospital Surge Centre2000m² Of CemfloorA temporary surge facility on the site of Addenbrookes Hospital to relieve pressure on the main hospital as part ofthe NHS' regional surge planFloor Screeding Solutions installed 2,000m2 of Cemfloor, the chosen screed for the project, which was supplied by Mick George Concrete, Cambridge.With the rising case numbers of Corona virus during the pandemic, hospitals were coming under increasing pressure for more critical care beds, and Surge Plans were put in place across the country to help alleviate this pressure.Addenbrooke Hospital in Cambridge sought to construct a ‘Surge Centre’ to cope with the additional demands on the hospital, and Cemfloor was chosen for the project due to its faster installation time and drying time compared to traditional sand and cement screeds. This helped to keep the project on track with its tight building schedule.Lewis Deck construction offered a strong light weight flooring option for the large pour area. As Cemfloor is a flowing screed, 500m2 of screed per day was poured over this by Dave Washbrook and his team from Floor Screeding Solutions, eliminating the need for on-site mixing.The main advantage Cemfloor has over other flowing screeds is the quicker drying times, and that it can accept foot traffic after 24 / 48 hours, meaning that construction could continue quickly and efficiently to meet the project deadline.

Vehicle/Pedestrian safety barriers for the new 627 space, 6 storey car park at the Derriford Hospital in Plymouth.Like many hospitals, Derriford in Plymouth has to match ever-increasing numbers of patients, visitors and staff with limited parking availability. The new 627 space multi-storey car park on the North West Quadrant will go a long way towards easing the situation for the daily 8,000 footfall to the hospital. Part of a 6.6 hectare site being developed by Wharfside Regeneration for Plymouth Hospitals Trust, the new car park was designed by international architects S333 and built by Sir Robert McAlpine Limited.The eco-friendly design features green walls with climbing plants on the two lowest levels, steel latticework on the next two and timber latticework on levels 5 and 6. We recommended our RB1X Spring Steel Buffers that ‘give’ in a collision to absorb impact forces and minimise damage to the barrier, the vehicle and the car park deck that the barrier is mounted on. After an impact, the barrier returns to its original position to provide ongoing protection. Berry Beam rails were used to give a more refined  appearance than the traditional Armco ‘W’ section.A BS 6180 compliant pedestrian handrail was mounted above the barrier on post extensions of 1,100mm high and the space in between filled with anti-climb mesh to stop pedestrians from falling through, or even climbing over the barrier.

The flat roof area at above the vast Guernsey Power Station had been suffering from water ingress as a result of failings in the existing EPDM membrane. Due to the expensive machinery housed within and the potential for widespread and costly disruption should the leaking continue.Guernsey Electricity turned to Sarnian Roofing Limited, a Polyroof approved contractor, to provide a rapid and effective waterproofing solution. The Protec System was specified, and work began quickly.The SolutionRemoval of the failed roof coverings to expose the concrete deck below began, and the BBA-approved Protec 20-year system was installed directly to the concrete. Due to its RapidCure technology, the system cures within 30-60 minutes, meaning less disruption for the client.The Protec System provides an flexible and seamless membrane that eliminates the risk of water ingress around penetration points common in industrial unit roofs. As the system is cold applied, there are none of the safety risks associated with the open flames and hot torches used with traditional roll-applied systems.Polyroof’s reputation has been built on the high level of technical support provided to clients before, during and after every contract.We like to work closely with our clients from the very beginning of a flat roofing project right through to completion and throughout the lifespan of the roof. From our experience, this is the best way to guarantee that all aspects of the roof are finished to the superior standards that our clients expect.

The International Convention Centre (ICC) Wales is an extraordinary venue designed for world class conventions, events and meetings.The result of a joint venture between the Welsh Government and the Celtic Manor Resort, renowned construction company, John Sisk & Son, was the main contractor on this 3500m2 project which also included a permeable and sustainable urban drainage systems (SuDS).AG’s premium granite block paving TerraPave® was the obvious paving choice for the convention centre as it offers a beautiful finish to complement a contemporary design. Additionally, it is a cost-effective, practical alternative to traditional stone paving. TerraKerb® also played its part in this high-profile hard landscaping project, adding a premium appearance to the ICC surrounding. With its widely recognised durability and weather resistance, it is now well established as a market-leading option.Tim Cave, Regional Sales Manager at AG, said:“A key challenge faced by AG was to create a high-quality permeable paving system for a large roof deck, capable of withstanding continuous heavy traffic. Our Xflo® Plaza was the perfect choice. AG’s Plaza block paviour is made using the most modern manufacturing techniques, ensuring it will stand the test of time and retain its high-quality aesthetics, whilst effectively managing the movement of water through the SuDS system. This is a pioneering but proven way of mimicking the natural movement of storm water and replacing conventional storm water drainage systems.”

When developing new buildings, it is always important to consider the environmental impact. Responsible sourcing of materials is high on every priority list, along with reducing waste to landfill. But what about the local impact, such as the effects on local wildlife? A living roof/green roof system, such as the one installed by the Premier Contractor at Seaford Head Golf Club, is a very clear example of the steps that can be taken towards reducing this impact and providing an alternative space for wildlife to inhabit. A warm roof system was installed onto a structural plywood deck, after which a vapour barrier and insulation boards were mechanically fastened to provide both thermal efficiency and air leakage control. After the underlying installation had been suitably restrained in accordance with a site-specific wind uplift calculation, the roof membrane was mechanically fastened to complete the waterproofing system. Our PVC roof membranes have been tested and can be utilised without the need for additional root prevention barriers (test standard EN 13948), and because PVC is extremely lightweight, they are the perfect choice for these applications, reducing pressure on the underlying structure. In conjunction with our Living Roof/Green Roof specialists, a site-specific living roof system was supplied and installed over the completed waterproofing.Waterproofing System:DANOSA Single Ply 1.5mm - AnthraciteConstruction Type:New BuildWarm RoofSector:LeisureApprox.
