New Asda store in Pyle, Bridgend
The building has a 6,000 sqm flat roof, including a canopy around two sides, all made from fibre cement sheets, typical of supermarkets and large retail stores.
A full survey was carried out on the superstore which highlighted the need to replace some of the existing composite panels. In addition the client was happy to replace the existing asbestos as well.
With the store not yet being open due to the recent sale and refurbishment already underway, the decision was made that now was the ideal opportunity to replace the roof with a brand new one which would provide peace of mind for years to come.
Asda bought the store from COOP and wanted a new roof and new cladding to the canopy. Under1 produced a specification and monitored the ongoing works on site
service descriptionUnder1 were commissioned to project manage the design and installation of the new roof. The chosen replacement product was Kingspan Composite Panels, a high-performance rigid insulation product. With existing contractors already in place they worked with them to deliver the project, overseeing and qualitychecking works on a weekly basis throughout.
Michael Sharples, lead consultant for Under1, said: “The key to the success of the new roof is not just the sheets themselves but all the gutter and ridge cappings which are essential to keeping the roof watertight for many years to come.
“Because of flu pipes and extractors coming up through the roof we also chose to use a new Triflex liquid waterproofing where these joined the roof – it is joins such as these where problems can so often start.
“We carried out a fastener test with our Seal Tester to determine if the new fasteners have been fixed to the existing purlins correctly. A number of fasteners were found to be loose or not fixed at the correct angle which could allow rain water to enter the building through the fasteners. This was immediately raised with the contractors and rectified before problems could arise.”
