F. Ball products have been used to install vinyl safety flooring at the Great Western Railway train depot in Penzance. Flooring contractors installed 400m2 of flooring in the depot. Firstly, to combat the excess subfloor moisture, which can cause extensive damage to floorcoverings and lead to costly remedial work, contractors used a combination of Stopgap F77 and Stopgap F78 Waterproof Surface Membranes. The fast-setting, minimal preparation Stopgap 1200 Pro smoothing underlayment was then applied over the area. A short time later new Polyflor Polysafe Standard PUR flooring was installed using Styccobond F46, a solvent-free pressure sensitive acrylic adhesive.

Family houses renovated... CHALLENGE 134 single family houses needed to be renovated to liveable conditions. The main problem for the architect and building contractors was the fact these houses had to remain occupied during the works. SOLUTION For the roof two prefabricated timber roof elements covered with the RENOLIT ALKORDESIGN roofing system were installed to replace the existing roof structure. The roofing elements consisted of a layer of OSB, a layer of 350 mm cellulose fibre insulation, another OSB plate and a 2 mm thick RENOLIT ALKORPLAN roofing membrane. The prefabricated roof element has a U-Value of 0.11 W/m². On top of the prefab roof elements hot water panels were installed. 

Heavy 3 slate has been used to rebuild a previously run-down village hall, into An Talla Loch Ness Visitor Centre, a visitor gateway to Loch Ness and the Caledonian Canal. The renovation project used Heavy 3 spanish slate for its similarities, aesthetically and characteristically, to the traditional Scottish Ballachulish.  Part of a £2.5 million project, the developers Loch Ness by Jacobite took over the building with the view of creating a base for visitors to embark on a journey along the loch. The extensive renovation of the Victorian-built Dochgarroch Village Hall has been re-named An Talla, meaning ‘The Hall’ in Gaelic. It now comprises of a reception, retail outlet and café, all built around a new central courtyard and external terrace overlooking the Caledonian Canal towpath and quayside. As the original slate used on the building was Scottish Ballachulish, Heavy 3 was selected for its shared characteristics such as its blue-black colour and thickness. Heavy 3 slate is the best choice for repair and replacement of traditional roofs in Scotland as it produced at an extra thickness, 7 - 8mm, meaning it is ideal for combatting Scotland’s inclement weather.  “As the Loch Ness centre is an extension of the original hall building which has a traditional Ballachulish roof, Heavy 3 slate was selected as the ideal match to maintain the aesthetic,” commented Ian Sharpe, roofing installer at Wyvis Roofing – contractor on the development.  “I specify Heavy 3 for many of my roofing projects as the likeness to traditional Scottish slate is unmatched by anything else on the market. As always, the installation went really well and the CUPA PIZARRAS team – who I use regularly for roofing projects - were on hand to assist if needed.“One particular quirk of this project was the family of bats that had taken residence in the roof of the building. As bats are a classed as a European protected species, it is illegal to remove them; so, we installed a number of lead bat vents, allowing the bats to fly in and out of the roof space freely – yet more wildlife for visitors to observe.” 

Burton Green Primary School is located in the historic city of York, an outstanding school at the heart of a local community this primary school strives for excellence. The challenging and nurturing learning environment allows children to learn and grow, while achieving the highest potential possible in all areas of the 21st century curriculum.When the roof began showing signs of ageing, it was clear that a long-term solution was required. Working with Project Managers Charles Garth and Principal Contractor Castle Special Projects, Polyroof would work towards providing the best solution to refurbish the ageing roof.The work required and condition of the roof needed to be established first, to do this a survey was scheduled to take place. The survey was conducted on roofing area and it was determined that there were 6 flat roofs that required refurbishment. Areas 1 to 2 were constructed of a built up felt with mineral cap sheet, 50mm PUR insulation, bituminous vapour control, asphalt, 12mm fibreboard and a 50mm woodwood slab deck with timber joists. Areas 3 to 5 were constructed of a built up felt with mineral cap sheet, 50mm Jablite insulation, bituminous vapour control, asphalt, 12mm fibreboard and a 50mm wood wool slab deck with timber joists. Roof area 6 was made up of built-up felt with mineral cap, plywood and timber joist. The original build-up of roofs 1 to 5 needed to be stripped back to the asphalt due to the aged condition of the built-up felt, numerous leak reports were reported. Roof 6 and its original waterproofing was to be retained and made good, later this surface would act as the substrate for the new waterproofing system.Once the survey was completed, a bespoke specification was written and it was recommended that the roofing areas would all benefit from a high-performance waterproofing system. In addition to this it was specified that the roof would be thermally upgraded to reduce the risk of condensation and provide lower fuel bills and energy consumption for Primary School further adding benefits to making improvements to the roof.Liquid Roofing Limited an experienced roofing contractor and Polyroof Approved Contractor was chosen to undertake the work to this project. The proposed system for this project would be Polyroof Protec Warm Roof System. Protec’s liquid roof membrane has a unique flexible hybrid polymer formulation and can be applied to virtually all common roof surfaces.The areas that were required for installation firstly needed to be stripped and removed back to the asphalt, areas 1 to 5 required this. Area 6 was then repaired of any defects and made good where necessary. All roofs required a deep clean, removing any dirt or debris that remained from the first stage. Once this preparation was completed an Air & Vapour Control Layer (AVCL) was then installed to roof areas 1 to 5 making sure that all surfaces are smooth and without voids.Using a Polyroof Twin Pack Insulation Adhesive the Polyroof RES insulation (T&G) boards were bonded and laid to each of the 6 roof areas completing the second stage of the warm roof upgrade. Before the last stage of the installation could begin all joints in the insulation were sealed using taping matt and Polyroof Protec Resin. Polyroof’s extra-tough GRP trims were then installed to create neat and robust edge detailing for exposed perimeters before the main Protec system application commenced.During the project there were some challenging aspects that required care and attention. The project featured a large array of different details ranging from installation of new substrates and trims for parapet walls to the removal of and preservation of tiles/cladding so that the Protec system could be applied correctly. These features required delicate work so that the original tiles/cladding could be reinstated after the application of the system was completed. During the project the rooflight that was originally in place was removed and replaced with a new, before this could happen the Protec system was taken up the upstands and then sealed under flange.Once the project was completed within the relevant time frame of the client and within the budget specified, the Polyroof Technical Services team conducted a detailed inspection showing a high level of workmanship which lead to the client gaining the trusted Polyroof Accredited System Guarantee.

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

Ghent Diamond CHALLENGE The Ghent Diamond is proudly overlooking the Ghent-Sint-Pieters railway station and surrounding neighbourhood. On top of a stonelike base with a pattern inspired by the city of Ghent’s historical architecture, an impressive crystalline edifice rises. The 33m high office building has – as the name indicates – not only the brilliance, but also the shape of a gigantic, polished diamond with numerous facets. The special design makes the building unique, and that is exactly where the difficulty lies: roof surfaces with different inclines, steep and hard-to-reach slopes, kinks in the façade and a serious wind load. On the pitched roof segments connecting the glass facade, an exterior roof finish with Linius RENSON blades is to be installed. Just for aesthetic reasons! Such a finish creates a nice play of light, shadow and reflection. But this can only be achieved if the finish has been executed perfectly! But how to execute the construction so precisely, and at the same time be perfectly watertight? A true challenge for both architect and roofing contractor. SOLUTIONFor the internationally renowned New York-based architects practice Asymptote this monumental Diamond project is just another jewel in the crown. Innovative and visionary, they always pursue extreme and experimental challenges. And yes, this impressive Diamond really was a challenge, especially for the Belgian ROTEAM roof experts. The special shape, the height and the different slopes up to 47° made it a complex, gargantuan waterproofing project. On top of the steel deck structure tongue and groove insulation panels were installed. This guarantees a strong, perfectly fitting and smooth construction. After all this is very important in order to achieve this monumental task. The high wind load and shear forces were decisive for the choice of roofing membrane to be used on this difficult structure. Asymptote architects therefore opted for the mechanically fastened RENOLIT ALKORPLAN F membrane. This PVC-P roofing membrane is specifically suited for such a project, thanks mainly to its flexibility, lightweight and long life.

Bilco UK has supplied an innovative replacement roof hatch for a medieval church in Norfolk. St Mary’s is one of the 653 churches within the Diocese of Norwich. When it came to providing a means of safe access to the roof area a product was required that was both technically and architecturally suitable. Medieval Masonry Ltd, a specialist contractor in the restoration and conservation of historic buildings with over 50 years of experience in the industry, installed Bilco UK’s S-50VMTB VersaMount® Replacement Roof Hatch.

The existing waterproofing had failed due to a previous poor installation, the result of which saturated the insulation below the exterior roofing. New high performance solutions were specified that included a range of IKO roofing waterproofing systems to protect both the flat and pitched roofing areas of the building. IKOslate, a robust and durable tile was specified for the pitched roof due to vandalism and the fragility of the current system, whereas a tapered scheme was required for the flat roofing - IKO Ultra Prevent alongside a cold applied liquid solution (IKO Polimar) for the more intricate details.

Find out why we recommend rafter ventilation slides when using spray foam insulation in pitched roofs where a high-resistance roof membrane is in place. The rafter slide not only provides ease of access to the external roof for future repairs/replacement, when ventilated appropriately, it can be effective at managing moisture.

The Proteus Waterproofing roof survey carried out found the existing flat roof system to be saturated. The existing roof build-up needed to be stripped back to the roof deck, with the main challenge of the roof refurbishment being the low up-stand heights available to the penthouses.The project required a flat roof system manufacturer involved at the initial roof survey and specification design stage, followed by the manufacturers technical back-up to assist with unforeseen and unexpected situations to ensure a successful installation of the new roof systems.High Performance WaterproofingThe terrace roofs above hated spaces demanded a waterproofing system with BBA certification. The fully bonded and seamless Pro- System® Plus was selected for its high performance and low odour, in conjunction with Proteus Pro-Therm Insulation to improve the roofs thermal performance and reduce the existing condensation risk.The flat roofs that were not above heated spaces required Proteus Pro-System® Plus low odour, seamless waterproofing overlay. Proteus Waterproofing worked closely with the Client and the Proteus Approved Contractor, which also acted as the Main Contractor, to ensure the installation complied with the specification design.Health & SafetySafety on construction sites is always of the utmost importance, as well as keeping disruptions to other trades to a minimum.

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.”

Arable farmer Ivan Banister talked to various agricultural building companies for advice before using local contractors to construct both parts of the new grain store. The first part of the new building was constructed with the secondary expansion undertaken and completed in time for the harvest. Eternit Profile 6 roofing sheets were selected for the project and installed by MJ Barrett.The roof was the most important consideration for Ivan and it was vital that the roofing material used on the store would resist the pressure from temperature and weather without cracking. Any problems in the roof and subsequent leakage would cause serious damage to harvested crops.Condensation had also proved a problem in older, steel roofed storage facilities at Warden Farms and the vapour permeable nature of Eternit fibre cement roofing sheets helps to minimise moisture levels within the new storage building.

George Abbott SchoolBauder Thermofol single ply waterproofing system with Bauder Euroglaze rooflightsSynopsisLocated in Guildford, George Abbot School is a secondary education school which provides education for 2000 people aged 11 to 18. The school had a history of leaks in the DT rooms above which a profiled sheet metal roof was installed.Following many attempted repairs, Bauder was commissioned to carry out a roof survey on the 228m² profiled sheet metal roof. The report identified issues with not only the gutter area, which was originally believed to be the problematic area, but also with the adjoining profiled roof and also with the large rooflight unit.Bauder Building BoardProject: George Abbott SchoolLocation: Guildford, SurreyRoof Area: 228m²Specifier: Baily GarnerApproved Contractor: Inspire Contract ServicesThe specification Bauder submitted a proposal to refurbish all areas of the failing roof:The gutter area needing standing water to be removed for which Bauder tapered insulation was proposed to create effective drainage falls.The adjoining profiled sheet metal roof requiring a new waterproofing system. The Bauder Profiled Roof Overlay system was determined to be the best solution, using bespoke profiled insulation boards specifically designed to fit the shape of the roof. The Thermofol U15 Fleece Back membrane was then specified as the waterproofing layer providing a robust yet lightweight waterproofing system to the roof.The existing rooflight unit, being one of the problematic areas of the rooftop, was also replaced with Bauder Euroglaze rooflights. Products appliedInsulation infill systemIntended for refurbishing profiled sheet metal roofs or increasing the thermal performance of existing insulated cladding systems.Bauder Euroglaze rooflightsModular rooflight designed to provide high standards of illumination, insulation and ventilation to the interior of flat roofed buildings.

Light grey was chosen to reflect the colour of the cladding as the aesthetics was a key objective for the client.The OMG Rhinobond induction welding system was specified as the installation method which provided multiple advantages to the project, not only saving time and fasteners, but also optimising the field fix pattern of installation and ensuring that the load on the roof was spread between the induction welding plates. Products appliedBauder Thermofol U15 FR MembraneA high grade virgin polymer Thermofol PVC membrane ensures the optimum membrane characteristics to deliver high performance and a BBA stated life expectancy in excess of 35 years.BauderSOLAR F An aerodynamically optimised system for flat roofs using framed modules and mounting units, securing them to the roof using membrane-to-membrane welding techniques. This installation method means that the roof is not compromised by penetrations of fasteners or is it ballasted.Project challengesThe design of the Transport Hub and city centre location proved to be the key challenge to this project. The unusual roof configuration required a bespoke insulation scheme using BauderPIR M, an efficient rebated PIR insulation board, in order to achieve the required U-value of 0.18W/M²K.The deck configuration equally made the installation of the Bauder Thermofol PVC waterproofing system complex with the perimeter zone having to be carefully marked in compatability the wind calculation which included measuring factors such as wind speed, altitude, direction and exposure. Bauder and Kovara Projects were required to work closely together to ensure all criteria of the wind calculations were met. 40 modules of the lightweight BauderSOLAR PV solution were installed on the west side of the Transport Hub’s roof.The location of the project, Gloucester city centre, presented logistical challenges. Delivery of the roofing products had to be carefully scheduled and managed to avoid creating congestion in the area.The resultThe installation required constant co-operation and communication to embrace the live site operations within the restricted city centre location whilst allowing the bus station to remain fully functional.

This asbestos cement roof was heavily contaminated with moss and lichen, following many years of neglect. Liquasil's asbestos roof coating, Asbestoseal was specified because it is the only such coating with BBA Approval for asbestos roofs. Also, the completed project came with a 10 year Latent Defects Insurance Guarantee. The roof now repels water instead of absorbing it and nothing can grow on top of the coating system, meaning it will stay moss-free forever. Call 0121 709 5352

KAL is a member of the Gowan Group, a family-owned holding company, directly controlling many successful trading companies as well as significant property holdings and financial investments in public and private companies in Ireland, Northern Ireland and the UK.The largest appliance distributors in Ireland, KAL rely on a 30,000 square foot designer showroom for unique kitchen and domestic appliances. Their showroom at Dublin’s Citywest is one of the largest of its kind in Europe showcasing all their kitchen and consumer appliance brands.The ChallengeAfter conducting a survey of the 1,000m2 roof, it was determined that the areas of the roof, specifically the office area, were in need of repair. Some areas of the original roof build-up were starting to leak and lap joints failing due to a poor install.Following the site survey and adhesion tests, a site-specific specification was produced for the client and contractor to overview once all parties were happy with the proposals. With some complex detailing work involved, a decision was made to overlay the existing roof build with Polyroof Protec System.The SolutionPolyroof’s Protec System, a hybrid polymer liquid system with extremely fast curing and installation times, was the chosen system of use for the project. Due to its fully cold-applied application, the works could be carried out during working hours, with little disruption to the office staff below and little working time lost for the client.IPRS Limited, an experienced roofing and panel repair contractor and Polyroof Approved Contractor, were chosen to undertake the work on the project. Firstly, before any work could begin, the original waterproofing of the office roof was pressure-washed and cleaned down. Once all initial preparation was completed, the Protec System application could begin.All areas requiring priming before the main system application were primed and allowed to cure. Any joints were sealed using taping mat and Protec Resin and allowed to cure. Once this preparation had been completed the main Polyroof Protec System, chosen in light grey by the client, was applied.The first coat was allowed to cure before the final coat was applied. Due the Protec System Rapid Cure technology, the finished roof could be walked on after just 30-60 minutes after applications. This allowed for large roof areas to be made fully waterproof within a matter of hours. After the inspection was completed, the client received Polyroof’s trusted Accredited System Guarantee.Taking away the challenges of flat roofing projects.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.

Celebrating its 50th anniversary in 2019, the iconic Bell’s Sports Centre in Perth, one of Scotland’s largest sports facilities, needed a new roof to protect the important building. With the previous roof membrane nearing 30 years old and in a state of disrepair due to the challenging Scottish weather, the centre needed a long-term and robust roofing solution.Planned by Perth and Kinross Council’s arms-length body Live Active Leisure, the £700,000 project also aimed to improve insulation and ventilation in order to enhance the venue’s environmental performance and efficiency. With the building needing to stay fully operational during the works and the added difficulties presented by weather and the domed shape of the roof, the project provided a real challenge for the contractors.Roofing:Mechanically fixed Sika Sarnafil S327-15 EL light grey over Sika Sarnatherm insulation S327-15 EL.

Belvedere CourtBauder Hot Melt structural waterproofing systemSynopsisThe impressive Belvedere Court 4-storey building, which was converted from a hotel into 16 prestigious residential apartments in 2008, recently underwent further development including extensions for additional accommodation, basement housing, a communal swimming pool, a theatre and an underground car park.As part of the refurbishment of the site, the failing waterproofing of the green roof on the car park roof deck needed to be removed and replaced. Bauder approved contractor, The Complete Roofing Company (TCRC), initially proceeded to remove the existing pathways and landscaping before removing the failed system and providing remedial repairs to the damaged roof.Bauder Building BoardProject:Belvedere Court​Location:Sidmouth, Devon​Roof Area:1,316m²​Specifier:The Complete Roofing Company LtdApproved Contractor:The Complete Roofing Company LtdEnvironmental Focus:Intensive green roofThe specificationWith the car park roof also being used as a recreational green roof for the residents of Belvedere Court, the Bauder Hot Melt Intensive Green Roof System was an obvious choice. The Bauder Hot Melt Bakor 790-11 EV with Polyester reinforcement creates a resistant monolithic waterproofing membrane whilst the Bauder AP2 root barrier provides resistance to the system allowing for a green roof to be installed above. As stated by BBA certificate 06/4350, this system provides a durable waterproofing solution for the service life of the structure that it is incorporated in. The resultOn completion of the waterproofing elements the roof was leak tested to ensure the roof’s integrity. The TCRC then installed the Bauder green roof components; PE foil, FSM600 protection membrane, DSE40 drainage layer, filter fleece and over 300 tonnes of Bauder intensive substrate. Finally, Rowland Gold turf was then installed with a drip line irrigation system installed under the turf. Upon final assessment, this project met the criteria to be issued a 20 year product and workmanship guarantee.System Installed1 BauderPLANT E 42Torch-on root-resistant, green capping sheet.

The new Leeds Arena was a £60m project by Leeds Council to create a striking new stadium, which has been crowned with a 7,500sq m Sika Sarnafil single ply roofing system, installed by experienced contractor Lakesmere. The fact that Sika Sarnafil was the first roofing manufacturer to be BIM ready played a huge part in the specification, and in turn improved the ability to review designs and rationalise ideas, whilst cost saving using BIM was highlighted through material specifications and design coordination.
