Non-woven, macro-holed polypropylene fabric known as Mapetex Sel to be used as reinforcement on the waterproofing membrane. Prior to installation of drainage cell and landscaping media, the applied membrane should be protected using corflute protection board.

It is crucial to conduct a substrate inspection to ensure that the waterproof membrane can be applied correctly according to the manufacturer’s recommendations. The adhesion between the substrate and waterproof membrane is dependent on having clean substrates. As part of the substrate preparation process, voids must be flushed, and joints should be filled. In some cases, the concrete slabs may not be laid with sufficient falls, and when this happens, an epoxy screed must be applied.
