The store had a felt roof which after failing caused leaks to the building’s interiors. RESITRIX SKW hybrid EPDM membranes are compatible with felt and asphalt and were used as a direct overlay solution which was applied over several different roof areas. The refurbishments were carried out on a tight schedule of five weeks. The self-adhered and efficient application of the RESITRIX membrane contributing to achieving this. The works were completed on time despite battling against the elements, which included a very wet period, wind and a sand storm across the capital.

The roof also installed 100m2 of WALKWAY membranes. WALKWAY is a non-slip, EPDM-based safety covering, complete with additional reinforcement which prevents ruptures and helps with all stability. There is a self-adhesive butyl layer incorporating a release film on the underside. WALKWAY is used to clearly demarcate the routes for maintenance access. The slip-resistant surface is a vital element of the product and encourages the safety of walking on the roof. Additionally, it provides an enhanced grip, even on sloped roof areas and in wet weather.
