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.
Due to the devoted levels of hydrocarbon we proposed Coreflex 60, this was the first installation of this system in New Zealand. Coreflex 60 consists of a reinforced thermoplastic membrane integrally bonded to a proprietary active polymer core (APC) technology layer. The two barrier materials combined provide superior waterproofing protection unmatched by any other product.
