A Sika Sarnafil waterproofing roofing system has proved to be the perfect fit for The Donyngs Leisure Centre, Redhill following a major £4.1 million upgrade and refurbishment.
The re-roofing project was initially to be completed in two phases but the Reigate and Banstead Borough Council was able to draw on more funds allowing both phases to be rolled out as one.
The new roof, which entailed overlaying a Trocal installation from 30 years ago now includes 2,000sq m of Sika Sarnafil waterproofing system. Surrey-based specialist trade contractor, Vision Design Projects successfully tendered for this project, whose operational manager and site staff had previously been involved with the original contractor who installed the old roof.
The isolating layer used was Sika Sarnafil type “T” fleece x 300g / m2 with the waterproofing membrane layer being S327-18EL which was mechanically fixed with IF/IG-C 82x40mm membrane pressure plates and SFS BS Stainless Steel self-drilling fixings. All up stands / outer eaves were then covered with preformed Sarnametal closures.
During the installation of the project, there were no crash decks fitted, just a cover over the swimming pool which was closed for the duration of the activities in this particular area, ensuring safety was first priority.
