Integrated Alumasc waterproofing system protects council office roofs

Posted by david.luukas

Bridgend County Borough Council’s 40 year-old Celtic Court building got a valuable new lease of life when a fully integrated Alumasc waterproofing system was installed – along with multiple products from Alumasc Exterior Building Products; external wall insulation and render from Alumasc Facades; and rainwater goods from Alumasc Rainwater.



celtic1The Local Authority renovated the building, for use in partnership with other Public Bodies, after the old waterproofing system had deteriorated significantly over the years and received multiple ad hoc repairs to extend its serviceable life. Bridgend Council selected Alumasc and their Carmarthen-based registered contractor, Central Roofing, to provide an effective, long term refurbishment solution by waterproofing the roof areas of the building.

Central Roofing completely removed the existing waterproofing system back to the deck where repairs were carried out to the concrete & screed.

They installed a new Euroroof vapour barrier to provide some immediate protection against the elements and fitted Alumasc PIR insulation, incorporating tapered gutters, to help the roof drain better. A fully engineered insulated felt render system was then laid, onto which they applied a non-penetrative Aluminium capping system.

celtic4New Aluminium rainwater downpipes were also installed, and the waterproofing project was completed when Central Roofing applied the Euroroof waterproofing system – which comprised a felt underlay and Euroroof MG3/4 capping sheet, which came with a 25-year System warranty.

Bridgend County Borough Council’s Paul Avo said: “Alumasc and their installer, Central Roofing, have been excellent throughout. The thoroughness of their initial site survey and the design solution they proposed were impressive, and the quality of the work undertaken was first-rate”.

Alumasc’s market leading Swisslab External Wall Insulation was used to provide the exterior walls with a highly efficient insulated system and final finish. The combination of these various Alumasc products gave Alumasc the opportunity to provide the full envelope, single source package for this project.
