"roof decking other materials"

2-6 Cannon Street is a high-end new build commercial office building located in the City of London. Alfresco Floors were commissioned by Frost Landscape Construction to supply and install the GRAD decking and rail systems, which were supported by the Buzon pedestal system. This was a particularly challenging project as steel planters were strategically located in the middle of the roof terrace so installation had to be carried out around the numerous planters. The finished outdoor space at 2-6 Cannon Street provides office workers with a unique roof top terrace.

Project involved decking a 350m2 the rooftop of a commercial block in the heart of the city. The owners wanted to create a roof terrace for staff. The customer chose the iDecking complete solution for it's superior look. Installation was carried out on an inverted roof. The contractor laid down a double layer of our aluminium frame onto Wallbarn MegaPad pedestals which provide a stable footing for the framework. The composite Moor Oak boards were stamped into position. Installers were able to achieve a great finish by accurately cutting the boards to fit neatly to edges and corners.

The Trinity Mews project is a residential property in Stepney, in the East-end of London. As a remediation project, the building already featured a roof terrace in disrepair that needed to be replaced. Originally fitted with timber, the wood had begun to rot away. The system used - TerraSmart AluminiumThis is a non-combustible decking system designed for use on terraces or waterproof substrates. The RDFR pedestals, with base rubber shock pads and ADS25 joists, formed the system substructure of the remediated terrace. The finish was made using ADB-60 aluminium decking boards in Anthracite Grey. The TerraSmart Aluminum system is IGNO certified meaning it satisfied the requirement to be A2 s1 d0 fire classified.Further improving on the timber deck it replaced, the system had to be durable and slip-resistant. As ADB boards are classified as a "low slip risk" on wet and dry and see no signs of wear after 100,000 footfalls, they comfortably met both sets of criteria.Location: StepneyCompleted: 2021Client: A property management company

RENOLIT ALKORPLAN scores high on Deltion College! CHALLENGE A sports field on top of the roof. A surprising and exceptional RENOLIT achievement that absolutely draws the attention… Deltion College in Zwolle (NL) really is an exceptional case. This college offers amongst others education courses to prepare for service in the Armed Forces - Navy, Army as well as the Air Forces. No doubt sports are an important part of life on the campus. Then came the inspiration to install an artificial grass sports field on top of the roof of the newly constructed multifunctional building. Space-saving and functional! The choice to specify RENOLIT ALKORPLAN as roofing material was a shrewd decision, as RENOLIT ALKORPLAN offers a solution not only for mechanically fixed roofs but also for ballasted roof systems… SOLUTION The highest rooftop, a steel frame construction, has been installed with a PES-reinforced mechanically fixed RENOLIT ALKORPLAN F roofing membrane. For the lower concrete roof – the sports field to be – a different product was required: RENOLIT ALKORPLAN L! A glass fleece reinforced membrane with an excellent resistance to microorganisms, specifically conceived for ballasted roofs. Before installing the insulation, a bituminous vapour barrier was placed on top of the concrete. Next came a first layer of 70 mm thick aluminium-faced PIR insulation, followed by a second layer of 100 mm thick unfaced polystyrene insulation. To avoid direct contact between the roofing membrane and the PS insulation a glass fleece separation layer was added. Afterwards the RENOLIT ALKORPLAN membrane was loose laid and hot air welded. In accordance with the RENOLIT installation instructions the seams were sealed with RENOLIT ALKORPLAN seam sealer. A little bit of effort for extra security!

Case study of the refurbishment of the Intelhorce textile industrial complex (1957-2004) to transform it into the new logistics centre of the company Mayoral Children's Fashion in Malaga. 

Eurosafe designed and installed several solutions, including step units, guardrail edge protection, stepped and levelled walkways, ManSafe® systems, and raised platforms around heat exchange units for engineers' safety. A fixed stair unit was proposed for emergency access and egress planning.

The project had strict schedules which meant that minimal disruption to the surrounding areas was essential. A waterproofing system was required that would meet the requirements from both the public and private sectors as well as provide a contemporary, aesthetically pleasing finish.

5 Everyman cinemas have been built in a new building in the centre of Harrogate which houses several other retail and leisure facilities.The cinema directly above the ground floor retail units required a concrete floating floor whilst the 4 other cinemas required heavy dry floating floors with large floor voids.Our local branch supplied and installed the floating floors which consisted of Stravifloor Channel isolation rails supporting timber/cement board sandwich constructions or Stravifloor Deck solution supporting a concrete slab.The wall isolation and ceiling hangers completed the box-in-box construction delivering the required sound insulation between cinemas and to the retail units beneath.

One of Cardiff city centre’s recent regeneration schemes, Capitol Quarter, required a multi storey car park to provide parking for the new office buildings within the development. To ensure the car park was protected and finished with the highest quality materials, the main contractor sought advice from Degafloor Ltd to ensure a suitable cost effective, high performance waterproofing system for the top deck, ramp and an inter deck area over occupied premises was specified. Following a full site visit and having assessed the client’s requirements in full, Degafloor specified the CP TD system with fleeced banding to substrate cracks and all upstands for the top deck, the CP HD system for the ramp and a fully fleeced CP TD for the area over occupied premises. Capital Quarter Multi-Storey Car Park Cardiff Why Degafloor Degafloor car park decking systems use highly advanced fast curing MMA chemistry to create flexible and incredibly durable systems that cure fully within just 1 hour of installation, even at temperatures as low as -10°C. They are completely waterproof, so guard against water ingress that could result in the decline of structures or damage to property (premises or vehicles). This combination of superior performance, skid resistance, rapid cure times and design flexibility, have contributed to the Degafloor range of car park decking systems becoming a popular choice for new build and refurbishment projects where speed and ease of installation, longevity and visual aesthetics are paramount.

The terrace of a central London pub garden is given improved cover with a large awning by Breezefree. The rear garden at The Fence, in London’s bustling Spitalfields district, is one of the largest in the City, giving the pub a unique selling point that’s promoted prominently on their website. Despite being a destination venue, the only shelter on the decked terrace area was provided by a pair of gazebos that allowed water to run off onto other areas of the terrace, and did not complement the venue’s design concept...

A 200 sqm, highly energy-efficient new build project in a remote location in the Highlands of Scotland. Built using sustainable materials, and with the timber frame sourced locally and wood fibre insulation used alongside SuperFOIL Insulation throughout. Powered throughout the year using solar PV and battery storage.Looking to increase the thermal resistance of the building envelope in order to reduce energy usage. With the building using an air source heat pump and underfloor heating, they wanted to make sure that any heat loss was minimised and it was vital that they chose the correct insulation for the walls and roof.Solution: SuperFOIL SF19+ is a multifoil product with a total of 11 layers, made of wadding, aluminium coated PET layers and Foil Laminated Outer Layers. At only 40mm thick and providing an R-value of 2.14 when used in a roof, SF19 can be used on its own or in combination with other types of insulation. A fully flexible product that provides a vapour control layer as well as acting as a radiant barrier.

Laying ceramic tiles on flat roofs, terraces and podium decks has been made easier with the development of the Rail System, an integrated substructure system to increase stability of suspended tiles. The Rail System incorporates an adjustable height pedestal with a special clip head fitting, a specially profiled aluminium rail which clicks onto the headpiece without the need for mechanical fixings and a top headpiece which slides along the rail to hold and position the tile. By tying the pedestals together via the rail, there is far less risk of an individual pedestal moving or changing height, leading to far less risk of a tile rocking over time. This assures the integrity of the upper surface and gives a health and safety improvement to the area.The rail gives added structural stability as the weight is distributed laterally along the rails and not driven directly downwards onto the pedestal beneath. The top headpiece can be slid along the rail to fit to the corners of the tile above. This means the edge of the tile does not necessarily have to be directly above the pedestal, giving much greater flexibility for positioning.Consider the possibility of a drainage outlet or other awkward detail being directly beneath the edge of a surface tile. Instead of having to cut the tile back, simply move the pedestals away for the outlet and let the rail circumvent the hazard. Position the top head in the correct place to fit around the corner of the tile and the issue is addressed quickly, securely and easily. The rail system brings greater lateral stability to the tiled deck and is a faster, more efficient way to lay porcelain tiles and slabs. It is a major technical improvement to suspended tile and slab installations.

A stunning refit of a listed building overlooking Green ParkDevonshire House is a Grade 2 listed gem residing in Mayfair, and we worked with Bain Capital and TP Bennett Architects and their respective contractors on the refurbishment of the fourth-floor offices and their four expansive external terraces. The challenge was to find a decking solution that was fully compliant with the latest Building Safety Regulations while maintaining the aesthetic of this historic London property.MyDek’s Luxura – an A1 fire-rated composite – was chosen for the project as it seamlessly aligned with the building’s aesthetics while delivering a robust, enduring surface for the upgraded outdoor spaces. The roof terraces had a limited loadbearing capacity that could not accommodate concrete paving and Luxura emerged as the ideal solution, allowing for top quality decking that remained well within structural limits.

The 2,500m2 basement extends beyond the property where a blue-green roof will be created over a suspended podium deck to form part of the garden. The Triton team worked closely with waterproofing and blue-green roof design specialists, EPG, to create a waterproofing strategy and utilised a comprehensive Construction Quality Assurance protocol agreed between Triton and EPG. The Triton team had been called in by main contractor, Era Build Ltd, to replace a previous supplier who had been unable to provide a warranty. After detailing was complete; Triton Approved Contractor, Cast Contracting Ltd (CCL), installed the systems.

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.

Our purposeAs one of the UK’s leading housing associations, the Guinness Partnership prides itself on providing high quality homes that meet or exceed current Standards. It is therefore committed to a continuous programme of maintenance and asset management across its 60,000 homes estate.As part of that process, the 13-storey 1980s-built Waverley Court in Crewe was due for refurbishment, including new windows and heating for the 95 flats therein. An initial survey highlighted that the 1200m2 roof was failing and in need of upgrade to maintain its weathertightness.Our in-depth roof report also identified that the insulation was below current standards. Safety on the roof for maintenance was also an issue: the existing handrail was originally erected as a temporary fixture, penetrating the waterproofing and providing inadequate rooftop security for working at height.Our solutionThe existing waterproofing had perished beyond useability. We advised complete strip of the existing back to the concrete deck, and building up a new thermally-efficient roof to meet current standards required under the Part L of current Building Regulations.Our TA-25 W Flat Roofing System for warm roofs was installed by Approved Contractor Everlast as sub-contractor to the principle contractor, Wates. To address the poor falls on the roof, the insulation was tapered to the perimeter. We achieved an overall roof U value of 0.17W/m2K, exceeding the current Regulatory requirement of 0.18W/m2K. In line with Safe2Torch guidelines, our self-adhesive system was used to detail around roof penetrations for extractor fans and similar plant.We highlighted and designed bridging details to maintain the fire integrity around compartment walls to comply with Part B3 of Building Regulations.We designed a new, permanent and safe handrail system. This is fixed to the brick façade of Waverley Court, avoiding any penetration of the roof fabric and thus maintaining its integrity and watertightness, whilst minimising maintenance requirements.“Langley’s expertise and attention to detail has enabled us to deliver on our ambition of providing homes that people want to live in. Langley’s performance has helped us provide a dry, warm, safe living environment that exceeds current Regulatory requirement. The independent insurance-backed guarantee covering design, materials and workmanship adds value to our long-term estate asset management.”

Archbishop Cranmer School in Taunton houses both a School and Nursery and looks after 250 pupils. The buildings have a unique look due to their angular mansard rooftops.The traditional slate tiles that adorned the mansard roofs were in urgent need of repair and Somerset County Council needed to replace the roof with a material that could match the visual properties of traditional materials, it was also necessary to increase the vandal resistance of the rooftop.

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.

Morris Blitz CourtBauder LiquiTEC cold applied liquid waterproofing systemSynopsisMorris Blitz Court is a residential housing estate in Hackney that has undergone an extensive amount of refurbishment works as part of the Decent Homes Programme. Included within the approved scheme was the renovation of all of the building’s balconies and walkways, as well as the transformation of the 1,000m2 concrete podium deck located above the car park into an aesthetically pleasing social space.Bauder Building BoardProject:Morris Blitz Court​Location:Hackney​Roof Area:1,400m²​Specifier:Mansell Construction Services​Approved Contractor:Armour Group​The specificationVarious waterproofing options were explored by the client, however, it was decided that the Bauder cold applied liquid systems would be the optimal solution given all the requirements.Project challengesOne of the major challenges for this project was the low door thresholds connecting to the podium deck, which couldn’t be raised, meaning that the build-up for the majority of the cold applied waterproofing and landscaping elements would need to be less than 100mm in height. Because of these restrictions the only drainage and protection board suitable within the system was Bauder’s Versicell 20, which is just 20mm in height but can withstand extremely high loading. The surface of the deck consists of three distinct finishes; permeable paving on the ground floor patios and walkways, artificial turf featuring fibreglass planters to serve as a communal garden and rubber mulch to create a play area for children.Balconies and communal walkways were waterproofed with Bauder’s cold applied reinforced waterproofing layer; which is extremely fast curing and can withstand foot traffic within an hour of being installed. Residents remained in situ throughout the installation so working hours were scheduled to accommodate for school hours. Despite the challenges encountered all works were completed on time and to budget. Products appliedBauder LiquiTEC SystemA cold applied liquid waterproofing system that offers the maximum versatility in roofing.

Located in the heart of the vast new Wembley Park regeneration project, the two residential buildings that make up the Landsby East and Landsby West development (Danish for village) are contemporary in design, with apartment interiors that continue the Scandinavian theme. Externally there are roof terraces and first floor level podium gardens, along with 280 generous balconies that add a stylish and aesthetic feel to the exterior finish of the building.A key element of the balconies was the installation of Isokorb® T structural break units from Schöck. The Schöck Isokorb® T units are structural, but their other long-term purpose is to minimise the risk of thermal bridging. Ineffective insulation at the connection points means local heat loss, resulting in more energy being required to maintain the internal temperature of the building. This is a major consequence of thermal bridging, but there are other issues too. Low internal surface temperatures in the area of the thermal bridge can cause condensation, which leads not only to structural integrity problems with absorbent materials such as insulation products or plasterboard, but the potentially serious occurrence of mould growth. So for any project involving balcony connectivity the prevention of thermal bridging is a critical issue.

Dublin City Council were particularly interested in IKO Carrara’s exceptional environmental properties with its view to adding photovoltaic panels (PV) to the existing building. PV panels in combination with IKO Carrara have greater efficiency, up to 25%, as the performance of the solar cells increases during sunny periods, at a lower ambient temperature.

Battersea Dogs and Cats Home in London, the best-known animal sanctuary in the world, is currently undergoing the biggest development in its 154-year history - a £5 million scheme delivered by main contractor, Sir Robert McAlpine. The development will bring the charity’s existing buildings and facilities into the 21st century and will include a new build, state of the art veterinary hospital which will be protected by an innovative new waterproof membrane – Cold Melt® from Proteus – a seamless application designed to work in harmony with the roof infrastructure and so tough that it has been BBA certified to last for the lifetime of the building.Quality Control An integral part of this transformation is the built up roofing system of 1,200 square metres of Cold Melt®. Applied by the Proteus Licenced Contractor, a 5 layer built up system was employed to offer a bespoke specification tailored to the client’s needs and budget.The built up system consisted of a layer of Cold Melt® Proteus’ own innovative, cold-applied liquid membrane, over which an insulation layer of Proteus Pro-Therm XPS was laid. The Licenced Contractor then added a separator sheet of Proteus Low-K followed by an attenuation mat and then three different finishes in three different areas of the roof – paving slabs, a green roof and decking.Health & Safety Proteus’ liquid applied systems are cold installed and therefore negate all the elements of fire risk when working in confined spaces. Of particular importance was the low odour that Cold Melt® exhibits, meeting all the health and safety criteria necessary to protect both the Licenced Contractor’s operatives and the dogs and cats home’s residents.Long term performance Cold Melt® incorporates recycled rubber-crumb and other organically grown products and when covered, creates an elastomeric, seamless and cold applied membrane which has a life expectancy longer that the design life of the building on which it is installed.

Natural sunlight and space were two of the key objectives for this extension located in South London. The client, an artist, writer, and former fine arts lecturer, had recently moved to London from Oxfordshire to be closer to her family, and was looking to produce a peaceful, tranquil space to help improve creativity when at work.“I had no fixed ideas about what I wanted, but I wanted more space because it was very small, very dark and I just needed to breathe” Client via Evening Standard.Looking to update this Victorian house into a future proof property, Atelier Baulier Architects worked with the client to achieve the radical vision of a virtually half opened roof through the use of a rooflight. Our Multi-Part Flushglaze rooflight was specified at just short of 8 metres which immerses the entire extension in daylight making the 21 sq. m. space feel much larger, hoping to improve the client’s productivity and focus. The art studio is located under the doubleheight volume, enjoying even light levels throughout the day. The writing room takes the vantage point of the mezzanine above the bathroom and is accessed from the first floor level through an opening made in the gable.Keen to retain discreet detailing to ensure the rooflight framing wasn’t distracting from the design, the Multi Part Rooflight was specified with silicone joints, as opposed to aluminium balustrades, making the product much sleeker. To help daylight flood the room even further, the unit was specified with three Wall Abutments on the high left and right side. The Wall Abutments are not visible from the internal view, this helped to enhance the desired discreet detailing.As stated, the rooflight was supplied in three sections with the frameless silicone joints segmenting each section; the three sections were sized to achieve an equal split when viewed from underneath. This meant that the end sections had to be larger to account for the upstand width.“We aimed to maximise the potential of this unusual site. Rather than subdividing the space the programme is housed within one continuous volume, allowing the daylight to flow through.” Aurore Baulier, Director, Atelier Baulier ArchitectsWith the house being located in a conservation area, the extension naturally blends in with its outstanding surroundings. Brickwork is a major part of this Victorian cottage and its extension. The new volume is a wood-fibre insulated timber construction overclad with bricks slips, resulting in a much lower carbon footprint than a traditional masonry wall. On the interior, brick slips dress the walls continuing the pattern created by the whitewashed brickwork of the existing gable.Atelier Baulier Architects worked brilliantly to maintain the nostalgic look of the building whilst also transforming it into a contemporary home, with the use of a glass rooflight proving to be successful in adding a vast amount of light and space to the originally dark and gloomy Victorian house.

Cranbrook Primary SchoolBauder Total Roof System (BTRS) with Tapered insulation schemeSynopsisCranbrook Primary School in Ilford, London, was experiencing some major water ingress due to the advanced deterioration of the existing roof system. A roof survey was conducted by Stuart Parratt, Bauder area technical manager, where core test samples were taken to identify the existing roof construction to deck level and to provide an indication of the roof condition. The survey revealed that the existing waterproofing was in extremely poor condition, with extensive evidence of water ingress.  Bauder Building BoardProject:Cranbrook Primary School Location:LondonProject Type:RefurbishmentRoof Area:440m² Client:London Borough of Redbridge Council Approved Contractor:Thameside Roofing Ltd The specificationThe original waterproofing had been poorly overlaid with EPDM which had subsequently debonded. Before the installers could begin laying the new system, they had to strip the substrate back to the original asphalt. The client required a robust system that would deliver durability, value and longevity. 390m² of bitumen waterproofing, Bauder Total Roof System (BTRS), was specified for the main roof areas and 50m² of our cold applied liquid waterproofing, LiquiTEC, for an area that had limited upstands due to clerestory windows that could not be repositioned. Products appliedBauderPIR tapered insulation  A lightweight and cost effective alternative method of providing falls to a roof, whilst also providing thermal insulation. The client opted for this scheme at Cranbrook to minimise standing water on the roof. Bauder Total Roof SystemA two-layer bituminous waterproofing system robust enough to withstand foot traffic and most permanently sited plant. For use within warm and cold roof scenarios, as well as overlaying existing roofing materials. BTRS meets current UK Building Regulations Part B for external fire protection and features torch-free and safe to torch installation on combustible details. LiquiTEC Cold Applied liquid waterproofing Utilising Bauder’s PMMA cold applied liquid waterproofing on one of the roof areas ensured a fully watertight solution around rooflights and below upstands that could not be raised.  Project challengesAlthough the deck appeared to be in a reasonable condition for reuse as part of the refurbishment, there were large deflections to some areas and the existing waterproofing that overlaid the original system had been poorly installed and had pulled away from the asphalt below and so needed stripping prior to works commencing. The existing insulation was inadequate and left the building falling short of the current requirements. A thermal upgrade was incorporated into the works using a tapered insulation scheme which helped to solve the deflection issues by creating falls on the roof. To meet the minimum upstand requirements, the existing extractor vents needed to be removed to allow for the increase in the kerb height. Large continuous structural rooflights providing natural light to the building below were deemed thermally inefficient. The rooflights were upgraded during the refurbishment to meet current standards.  The resultBauder systems are only installed by Bauder approved contractors to ensure quality. The installation on this project was expertly carried out by Thameside Roofing Ltd, overseen by Dave Gregory and John White. After sign-off from Bauder site technician, Paul Osbourne, this system was awarded a comprehensive guarantee.  Systems installedBauder Total Roof System (BTRS) with Tapered insulation1 Bauder K5KHeavy duty, torch-applied SBS elastomeric bitumen capping sheet featuring a spunbond polyester reinforcement to allow the finished product to cope with structural movement without fracture, and a mineral finish to provide protection against UV degradation.2 BauderTEC KSA DUO Technically advanced self-adhesive SBS elastomeric bitumen underlayer with “DUO” lap technology to ensure thorough sealing of lap joints, even in lower temperatures. 3 BauderPIR FA G16Tapered PIR Insulation board manufactured in accordance with BS EN 13165 with no facings.

A long-awaited motorway service area on one of the countries busiest junctions - north of Rugby, at Junction 1 of the M6 - opened at the end of April 2021, bringing confidence to hauliers and logistics companies to make the switch to electric vehicles with provision of 24 ultra-rapid electric vehicle charging points.Around 3,500m2 of Tata Steel’s RoofDek D159 structural decking was used to form the support structure for the standing seam roof of the service areas main amenity building.

Ronacrete was called to a site meeting at The Brunswick Centre in February 2017 to discuss detailing of Ronafix floating screeds laid to falls where the required balustrade heights on the podium decks restricted the minimum screed thickness. It was agreed that a minimum screed thickness of 35mm could be applied if plant and materials were only positioned on thicker sections of screed until after granite paving had been laid, to ensure that heavy point loads did not cause deformation of the insulation boards.

County Hall - LondonSystem Used - TerraSmart Aluminium IGNOA hub for businesses, a site of attractions and accommodation, London's iconic County Hall is as stunning on the outside as it is on the inside, made even more beautiful thanks to our TerraSmart Aluminium.In order to create a venue for events, Coronado Property Developments Ltd needed a solution for the huge steel floor installed into the lightwell.A Grade II listed building required a decking solution that would complement the overall aesthetics and cater for the increased load requirements: the design load went from a 2.0kN Concentrated Load and 2.5kN/m2 uniformly distributed load (UDL) (used for areas of residential activities, typically used for balconies) to a 4.0kN concentrated load and 5.0kN/m2 UDL (as an area where people may congregate).TerraSmart Aluminium was selected as the ideal system to meet the client's loading criteria. Aluminium decking is a lightweight system when compared to other paving solutions, but very strong. Coronado Property Developments Ltd were very impressed with the solution provided by RYNO and the work done by Pritchard & Pritchard, who installed the system in both lightwells in the building.The TerraSmart Aluminium system featured the ADB80 Deck Board, selected specifically for its increased top surface thickness, delivering superior durability, ADS50 Aluminium Joists to suit the spans of the steel frame underneath, and RD-FR Non-Combustible Joist Support Pedestals for guaranteed supporting strength.The steel grillage was supplied by another manufacturer and installed around the decking to meet the ventilation requirements of the air-conditioning units below.The County Hall was opened over 100 years ago by King George V and it's great to see our systems in London's most versatile, historic building.

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.

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.

Battersea Reach, an award-winning development consists of 1,350 apartments spread over 14 separate buildings surrounded by beautiful landscaped gardens, shops and cafes. Buzon UK supplied and installed the DPH pedestal range for the composite decking and paving to many of the terraces and balconies across the 14 separate apartment buildings. The DPH pedestal system is perfect for use at roof level as they allow for 5% slope correction and can accommodate a range of services beneath floor level as well as giving excellent drainage.
