Sika products have played an important role in ensuring that Mellor Brook, an exclusive new development constructed by award winning PH Homes, will remain watertight. The development near Stockport consists of 12 properties, seven of which are built partly into the hillside, with the rear gardens being at first floor level.
To ensure that these properties in the village of Mellor are protected against water ingress and remain habitable, the retaining wall and floor slab were constructed using a dual system from Sika Limited. This consisted of SikaProof® A12, a totally new concept in membrane barrier design, together with the Sika® Watertight Concrete system. This was to ensure complete watertightness of the ground floor, adhering to the principles laid out for Grade 3 of BS 8102:2009.
Construction joints on the project were sealed with Sika® Tricosal® Metal Waterbar. This consists of a galvanised metal sheet with a layer of composite film on one side that bonds closely and permanently to the concrete. This acts as a physical barrier to the passage of water through the joints. The Sikadur® Combiflex® Jointing System was used to seal the movement joints. This consists of a Sika® Hypalon Strip and Sikadur® -31 epoxy resin adhesive. Combiflex Hypalon Sheet is a highly elastic, rot-proof and chemically resistant sealing sheet that is fixed with Sikadur® -31, an epoxy resin based adhesive that establishes a strong bond to the substrate.
With this small exclusive housing development now complete, Sika has once again provided a proven, high performance waterproofing solution that will ensure these luxury homes will stand the test of time.
