Thanks to the use of reinforcement with a high mass per unit area and continuous non-woven polyester stabilised by means of glass strands, Dermabit Extra guarantees outstanding mechanical performance and dimensional stability (±0.2/0.3%)

Casali Dermabit Extra is specially designed for large surfaces subject to high thermal stress due to direct sunlight or high temperature build up.

The top is finished in silica sand, natural or black slate chips disseminated uniformly and firmly anchored; there is a smooth bottom finish in torched off polyethylene sheets.

WQIP Building

Due to the location of the building in the Wynyard Quarter there is a high concentration of contaminants, high water table and saline. A waterproofing membrane was required not only to handle hydrostatic pressure but also to act as a vapour barrier protecting indoor air from potential ingress of hydrocarbon vapours.
