Waterproofing // Bitumen membranes against water vapour transmission and ingress of radon gas

Only metal foil can effectively prevent water vapour transmission and the ingress of radon gas. Bitumen membranes for this purpose have a combined carrier consisting of a reinforcement layer and an aluminium foil barrier.
