Sheet Membranes & Structural Waterproofing

Self-adhesive, liquid applied, multitype render, loose laid, welded and active sheet membranes prevent the passage of water ingress.

​

Sheet membranes are typically used for basement tanking and damp proofing, as well as providing a barrier against ground gases. These sheet applied systems have a factory controlled thickness for in-built quality control and are commonly known as a Type A (barrier protection) form of waterproofing. Sheet membranes are an element added to the structure to form a waterproof barrier that will not allow water penetration.

​

These type A systems can be used in conjuction with type B and type C as defined by BS8102
