Ruberoid Hyload Gastite DPC is made from bitumen modified with rubber. It has a polyester reinforcement with an aluminum foil core that is finished with sand. It is obviously very strong, but it also produces a gas-tight system that protects against harmful gases such as radon, carbon dioxide and methane. This means that this product is ideal for use on brownfield sites. It is flexible and easy to install. For domestic use, see Ruberoid Hyload Housebuilder which is a cost effective damp proofing course that is easy to work and install.
