Elastoplastomeric membrane with bitumen underside rivets, allowing water vapour to diffuse and provide waterproofing in base layer.

Used for both new construction and renovation work, on damp surfaces where blisters can form in the waterproof layer. It can be installed as a visible layer directly on concrete or to renovate an old bituminous layer which is no longer waterproof. The water vapour is drained through aerators which are easy to install in the Vapordiffuser membrane. Vapordiffuser can also be used on substrates such as certain types of insulating panels that can move and damage the waterproof layer.
