Visqueen Zedex Housing Grade DPC is based on the same polymer technology as Visqueen Zedex CPT DPC. It is designed to provide housebuilders with a robust, higher performing and cost effective alternative to traditional British Standard DPCs. Visqueen Zedex Housing Grade DPC is strong and flexible remaining workable throughout the seasons. It can be used with a wide range of products such as silicon mastics without causing discolouration, and bituminous liquid DPMs. Such compatibility is essential to ensure a continuous waterproof barrier for the lifetime of the building.
