Damp Proofing

Damp Proofing Membranes have been manufactured by RIW for over 80 years.

When RIW commenced trading in 1921 it specialised in liquid damp proofing membranes. However, the range of membranes now consists of not just liquid products, but a range of sheet membranes, drainage boards and sodium bentonite based products. All these membranes share the same function - providing specifiers, users and clients with safe effective basement tanking.

A useful starting point when designing a structure that requires a damp proofing membrane is BS8102. This official document describes the various steps that need to be followed to ensure effective basement tanking.

The first step is to determine to what use the basement will be put. BS8102 describes four standards of basement tanking, ranging from the lowest, which allows some water ingress, to a totally dry environment.

Once the grade has been selected soil conditions need to be determined so an assessment can be made as to what levels and degrees of water pressure the membranes will be subjected. Only when these factors have been considered can the design and the type of materials be selected.

Although in theory the selection of damp proofing membranes and design of basement tanking sounds a relatively simple task, there are many decisions to be made. RIW Limited has over 80 years experience of waterproofing and tanking and has an extensive range of membranes and systems.

RIW Limited offers the benefit of this experience free of charge, to anyone involved in damp proofing membrane design and application. We can assist in the most appropriate structural tanking design for and then advise on the most appropriate membrane, for the selected design. In summary RIW Limited can assist with every aspect of successful waterproofing design and selection of your damp proofing membranes.
