Sto has supplied the StoTherm Mineral K external wall insulation system with StoLotusan render for the new Day Case and Eye Unit building at Chorley and South Ribble Hospital. Specified by Gilling Dod architects of Chorley, who worked closely with the main contractor Tilbury Douglas, the StoTherm Mineral K system combines impressive insulation with excellent fire protection characteristics. With an A2-s1, d0 reaction to fire classification in accordance with BS EN 13501-1, the non-combustible mineral fibre insulation is fully bonded to the substrate and therefore no additional firebreaks are required. Ideal for both new-build and refurbishment projects, its efficient single-leaf construction also means that interior space within the building is not reduced.  For this project, the system’s mineral fibre insulation boards were secured to the lightweight steel frame and sheathing board substrate with mechanical fixings and StoLevell Uni adhesive and levelling mortar. A StoLevell Duo Plus reinforcing coat embedded with Sto-Glass Fibre Mesh was then applied to the face of the insulation boards, with StoLotusan and StoSilco renders used for the final finish on different sections of the building, using light colours from Sto’s architectural colour range.  StoLotusan is the only render available that uses Sto’s patented Lotus-Effect® technology which delivers impressive water and dirt repellence. It forms a unique surface texture, similar to that of the lotus leaf, that causes the rainwater to run off the render quickly and easily, removing any dirt or dust as it goes. Providing outstanding resistance to the growth of algae and fungus, the building will retain its looks for many years to come.  The new Day Case and Eye Unit is the result of a major £17.5 million investment in developing enhanced ophthalmology and day case services. The new Day Case and Eye Unit now offers an extensive range of diagnostic and treatment facilities for patients with medical eye conditions.

The UK’s leading telephone answering specialist Moneypenny had steadily been growing since its inception in 2000. Its main business is looking after telephone calls for businesses.To no one’s surprise, the company found itself struggling for space to accommodate its ever-expanding workforce. Staff ended up occupying five adjacent offices, which were physically separated from each other, as was the staff.A solution had to be found. It was decided to invest in and create a new modern office building befitting the growth and success of a successful modern-day enterprise.Moneypenny engaged the help of AEW architects to design a new and exciting office environment. With space to house 1,000 staff, Moneypenny wanted to have a new headquarters, which were both efficient office spaces, as well as a great environment for its staff to operate in. Staff members were asked for ideas for their new work environment. The industry norm was challenged and the resulting designs were an antithesis to most modern office buildings.Pochin Constructions were chosen as the main contractor to build the new headquarters. A 10-acre site was chosen in the open countryside for the amazing new office space, miles away from any inner city environment with all its noise and distractions.In turn, RCM were asked to supply its 12mm Cemboard to the construction, because of the building board’s excellent acoustic properties, which were a major consideration for the construction of the call-centreEventually, a 91,000 sq ft building had been designed and built, to create the perfect environment for call handlingThe end result was an amazing building, with plenty of natural day-light, excellent office facilities, with great down-time areas, complete with a tree house and a pub.Moneypenny’s new headquarters have exceeded everyone’s expectations. The new building provides the right balance between productivity and down-time. A true testament to imagination, good architecture and quality building materials.

The historic Bell Street Stables in Glasgow has recently undergone an extensive conversion, featuring the installation of Alumasc’s Flushjoint aluminium rainwater downpipe system.This magnificent period property has an interesting history. It was built between 1896-98 by A. W. Wheatley, originally to house horses working to pull the Glasgow City Council Cleansing Department’s refuse collection carts. In 1955, the building was redesigned to provide a separate entrance for the Police Department who shared the property with Cleansing until the 1980s. Situated in a prime position within the Merchant City area in the city centre of Glasgow, the building was converted to form 52 mid-market affordable rented flats by the Construction and Manufacturing Group (CCG) on behalf of Glasgow Housing Association (GHA) and Lowther Homes, during a two-year construction programme. The renovation was completed in 2019.A major requirement of the renovation was to conserve as much of the building’s heritage as possible, which included all exterior aspects. This involved the upgrade of the stone elevation, replacing all windows and making repairs to the roof and rainwater system.Flushjoint aluminium downpipes along with contemporary hopper heads were specified for their contemporary design. The installation was completed in a non-standard RAL colour to match and complement the window surrounds.

RezTred was installed for its long lasting anti-slip properties and to highlight the edge of each step, therefore, virtually eliminating the risk of a fall on the staircase.

Shooters Sports bar is a modern sports bar located in Neath Town Centre, a principal area of Port Talbot, Wales.  A popular venue, well known for its 6 screens showing live sports, licensed bar and pool, American pool and snooker tables.Delta Registered Installers, Tywi Damp Proofing were first approached to offer remedial assistance with a section of wall which was experiencing severe water ingress.The structure being of reinforced concrete and old wall construction was allowing water ingress via cracks in the structure.Most faults in older structures which allow water ingress are either damaged or deteriorating mortars.Any cracks in the brickwork or substrates will also allow water to enter a structure and would need addressing in creating a Grade 3, habitable space under BS8102:2009 “Code of practice for protection of below ground structures against water from the ground”.Prior to proposing remedial works, ground water assessment, drainage and associated risk assessments were all undertaken.

BackgroundWith stunning southerly views across to the Isle of Wight and also westerley along the Solent to Hayling Island, Portsmouth and the Millenium Tower, Marineside, a development of three-storey properties at Bracklesham Bay, is a dream location for anyone to live.However, whilst a prominent beachfront location comes with spectacular sunsets and unrivalled tranquillity, it does leave buildings highly exposed and prone to weather damage.This was the case with the Marineside development which showed signs of high coastal corrosion and were in severe need of regeneration both aesthetically and internally to address thermal underperformance.K Systems teamed with CBG, Envirorend SE, and Harrington Design to complete the low-rise refurbishment project, with three main objectives:- Remediate problematic substrate- Improve thermal performance for the benefit of residents- Revitalise a tired and unattractive exteriorAs with all projects, K Systems began a detailed scope and specification process with full involvement from all parties, including deploying digital technology to provide an inspirational viewpoint for the client to understand what the refurbishment would look like at completion.Our ServiceFollowing extensive planning, K Systems brought the client’s vision to life and created a beautiful collection of revitalised waterside homes on the banks of Bracklesham Bay.The refurbishment of Marineside wasn’t a straightforward project and required comprehensive scoping to ensure optimal delivery and 100% satisfaction levels amongst current residents.Therefore, it is a notable triumph for K Systems to have delivered a successful project, within budget, without delay or compromise on quality, that not only met but exceeded the requirements and expectations of the client.Each structurally sound, aesthetically pleasing dwelling boasted excellent thermal performance properties, achieving a U-value of 0.30W/m²K, allowing residents to benefit from more thermally efficient homes and experience a reduction in energy consumption.K Systems in collaboration with CBG, Envirorend SE and Harrington Design delivered beautiful, clean, crisp, aesthetically attractive properties, each with a protective exterior finish which will provide resistance to the elements for years to come.Technical Project DetailsOnce the existing façade was removed it was clear that the block substrate had high level corrosion due to the harsh coastal environment it had endured since being built in the 1940s.Multiple areas of the three buildings had to be completely removed and replaced using a medium density block that achieved superior pull-out test results. This was a recommendation by K Systems which enforced confidence with not just the client but the homeowners too as the best way to ensure longevity of the buildings.The removal also revealed that the substrate was uneven and unsafe. K Systems identified that extensive dubbing out was also needed with these buildings. Dubbing out meant the insulation boards were installed line and level giving a crisp and professional finish.The Marineside buildings were solid block construction making them extremely inefficient and presented an expense to the homeowners during winter months due to insufficient thermal performance.Utilising its years of unparalleled expertise, K Systems specified the industry-proven Mineral Wool insulation system for the project to address the aged façade and significantly boost the thermal performance of the building.K Systems Mineral Wool insulation (a mat of rock fibres which prevents the movement of air) has an industry-leading ability to generate exceptional thermal performance. That made it the perfect choice for the Marineside refurbishment as it would combat the heating issues faced by residents whilst retaining the solid foundations of the existing building.Other technical benefits which made the K Systems 110mm Mineral Wool system the ideal specification for this refurbishment include:- its level of fire resistance and non-combustibility, ensuring the building met all safety regulations required for residential buildings in England- its excellent acoustic properties, ensuring coastal noise absorption further enhancing the peaceful and tranquillity of the area- its environmentally friendly composition as it is free from gases with ODP (ozone depletion properties) or GWP (global warming potential)Due to the coastal location and exposure to the elements, it was vital that this refurbishment guaranteed total water tightness. K Systems worked closely with the roof installers ensuring that the parapet details were correctly detailed making the system as a whole watertight.The exterior finish was just as important as the internal construction and detailing. The Bracklesham Bay area has a level of prestige and the aesthetics needed to reflect that. K Systems finished the Marineside complexes with a silicone thin coat render, which is extremely breathable and resistant to the elements, in shades Limestone White and Granite. This completely transformed the aesthetic of the residential blocks making them much more appealing to potential dwellers.Envirorend SE commented:“ We secured the refurbishment works at Marineside , for a good client and works started in January 2022. The scope of works was to make the 3 blocks more energy efficient. Situated directly on the beach, the location made the install very challenging as the weather was not very forgiving at that time of year. The existing substrate was all over the place so a lot of effort was put in to get the walls looking line and level while staying within the remit of the specification. Works were completed in July 2022 and to a very high standard for all to see. “

After detailing was complete; Triton Approved Contractor, Cast Contracting Ltd (CCL), installed the systems.

The new generation of M-Tray® modules were used on this office building in Poklington, Yorkshire. This project was in the heart of the Vale of Yorkshire, within and Area of Outstanding Natural Beauty and planning sensitivities dictated a green roof was needed on the office building. The clients wanted the existing farm buildings, which had been converted into offices and storage space, to blend into the hillside with the structures having the very lowest impact on the surrounding countryside.The timber framed building meant a low weight solution was required so the 100mm deep pre-grown modules were ideal.

Internally and externally waterproofing the below-ground developments of the extended Christian Dior store on New Bond Street, with Newton 403 HydroBond, Newton 107F and Newton System 500.New Bond Street has been one of the most prestigious retail streets in London since it’s 18th Century beginnings, and in 2011 was named as the second most expensive retail street in Europe after the Champs-Élysées in Paris. The Christian Dior name has also been synonymous with haute couture and luxury retail since its own inception in 1947.This project required both the internal and external waterproofing of the extended basement area of Christian Dior’s flagship London store. A significant extension of the existing floor space on this stretch of famous London road, the extensive basement area will be used as stock rooms, changing rooms, and staff and shop floor areas. It was therefore a crucial requirement to achieve a completely dry internal space.The property line construction between two existing buildings meant that there was a requirement for waterproofing both new and existing structural elements, including pile caps, underpinning, a new reinforced concrete slab, existing foundations, and also existing vaulted areas at the front of the building which extend below New Bond Street.Because a completely dry internal environment was required, (defined as Grade 3 by the BS 8102:2009 Code of Practice for The Protection of Below Ground Structures From Water From The Ground) the proposal put forward by design specialists G05, in consultation with Newton, was a combination of Type A and Type C waterproofing systems. Due to the fact that the build was between the flank walls of two existing structures, the Type A system comprised of a combination of the hydrophilic, fully-bonded Newton 403 Hydrobond membrane pre-applied below the new concrete slab, and was linked to the cementitious, flexible Newton 107F membrane, which was applied to the internal faces of the walls and the prepared internal areas of the vaults.Following the application of the Type A system, a Newton System 500 Cavity Drain membrane system (Type C) was applied to the internal wall and floor areas by Newton Specialist Basement Contractor Advanced Preservations Ltd, who also guaranteed the work. The system included perimeter drainage using Newton Basedrain, and two Newton Titan-Pro pumping systems. The under-pavement vaults were lined internally with the Newton 500 system.Not only was continuity achieved with the waterproofing systems across numerous below-ground building mediums and scenarios, but the waterproofing system also conformed to the recommendations of BS 8102:2009 for combined waterproofing protection, where even the slightest form of water ingress is unacceptable.The internal areas were also successful in achieving an environmental Grade 3 with regard to their degree of water tightness, meaning that they will be suitably fit for purpose and use by both Christian Dior’s staff and customers.

Easy to handle, even for this incredibly large project.The Costco store in Wembley occupies a site close to the national football stadium.

Eurothane® Eurodeck was just perfect.”About Eurothane® Eurodeck:Eurothane® Eurodeck is compatible with mechanically fixed single-ply systems, benefiting from high compressive strength and excellent dimensional stability that ensures the flat surface finish required for optimum performance in new build and refurbishment projects. It is faced on both sides with a multi-layer coated aluminum foil.

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.

D-marc 105TM demarcation system – a collective protection demarcation solution. The doctrine “prevention is better than cure” is one that rings true in so many instances. Common sense tells us that it much better to prevent a fall than it is to arrest the fall once it has occurred. The Working at Height Regulations (WAHR’s) 2005 reinforce this argument. Whilst in many instances it is not always practical to remove the risk of a fall; rainwater outlets will always require cleaning, rooftop plant will require regular maintenance etc.. there are a number of ways to protect the worker from the immediate hazard the fall presents. The simplest way and that which much closely echo’s the doctrine “prevention is better than cure” is to keep the worker away from the fall hazard. The most effective way of achieving this and that which is advocated by the WAHR’s is through the provision of a Collective Protection solution. A collective protection solution is one which will “collectively protect all those who access the area”. In a rooftop situation where the hazard is a fall from the roof edge, Collective protection can be achieved by raising the parapet or through the installation of a full perimeter guardrail. Alternatively the worker can be kept a safe distance from the roof edge through the installation of a demarcation system. –Health and Safety in Roofwork HSG 33 states that “where work is not done at the edge, demarcation barriers can be provided at a safe distance from the edge (usually at least 2 meters), e.g. work on an air conditioning unit in the middle of a roof.”.      An example of where The D-marc demarcation system has recently been specified and installed at Crown Woods College, Eltham to provide safe access to rooftop mounted plant. The client was looking for a solution that would;Provide a collective protection solutionNot penetrate the existing roof covering and therefore not compromise the roofs waterproofing or air-tightness.Be lightweight so as not to require an additional support structure.Provide easily identifiable access routes ensuring no exposure to fall hazardsBe low maintenance and ideally have good environmental credentials.  D-marc was able to meet all these criteria and has the additional benefit of giving the customer the piece of mind that whilst it does not rely upon any means of mechanical fixing to the roof structure, it is tested to withstand wind speeds in excess of 105 mph. Such testing is a requirement of BS6399-2 Code of Practice for Wind loads which states that all components that form a building are required to withstand a 1 in 50 year wind speed.   D-marc was used extensively on the project as part of the collective protection demarcation system to create clearly defined safe access routes across the roof to theplaces requiring regular maintenance work. Having created the safe routes to the places of work, the D-marc was then used to demarcate the safe working zones upon the roof top. To ensure a complete collective protection solution was provided in isolated areas where it was not possible to keep the worker away from the fall hazard a guardrail was used. The easy to install, non penetrating D-marc system creates a clearlydefined access route and a safe working zone for all those undertaking regular rooftop maintenance works.

This was a large roof terrace on a private domestic project. The area was flooded and had needed to be re-laid with waterproofing and a significant fall constructed into the deck to allow the often considerable amounts of rainwater to escape the roof deck. The contractor asked Wallbarn for a suitable but cost effective solution so we recommended Wallbarn 9mm rubber supports along with levelling shims. The area was re-waterproofed in the inverted waterproofing method, the membrane being covered with rigid insulation boards and a loose laid geotextile fabric to act as a separation layer .

Fort DunlopBauder Total Green Roof System (BTGRS)SynopsisDuring the recent regeneration in and around Birmingham, innovation has been a key factor; a theme optimised by the redevelopment of the Dunlop Tyres warehouse which has been transformed into 45,000m² of office space and a 6,000m² hotel.Bauder Building BoardProject:Fort DunlopInvestor:Urban SplashLocation:BirminghamArea Size:7,100m2Architect:Shed KMContractor:James M Green Company LimitedThe specificationPractical challenges such as the reduction of noise pollution and maximising the building’s lifespan were all met by the Bauder Total Green Roof System with an extensive landscaping of sedum. The planting scheme provided instant coverage as the sedum was laid as pre-cultivated vegetation mats. Green roofs have excellent acoustic qualities for both external sound (up to 3dB) and internal noise (up to 8dB). This proved essentially in the selection of the Xero Flor blanket due to the proximity of Fort Dunlop to Birmingham Airport. The resultThe entire solution provided a watertight installation in conjunction with a 20-year guarantee whilst making the structure both environmentally friendly and aesthetically pleasing.System installedBauder Total Green Roof System (BTGRS) 1 BauderPLANT EA torch-applied, root resistant capping sheet.

After testing Millboard in situ for six months, where it passed the test for anti-slip and hassle-free maintenance, Coventry University asked their landscape architects, Plincke, to incorporate Millboard into their space design. As the university is in a built-up, urban area, there was little recreation space for students and staff, with limited space at ground level to create parks or gardens. The Millboard collection’s versatility made it ideal for Plincke’s innovative roof terrace design. The final result is a stunning, all-weather space in the heart of the city.
