Basement Drainage

Basement Tanking and Basement Drainage products have been manufactured by RIW for over 80 years.

When RIW commenced trading in 1921 it specialised in liquid products for Basement Tanking.

However, the range of Basement Tanking products now consists of not just liquid products, but a range of sheet membranes, Basement Drainage boards and sodium bentonite based products. All these products share the same function - providing specifiers, users and clients with safe effective tanking and waterproofing.

When designing a structure, useful starting point is the fact that it needs to comply with the British Standard regulations BS8102. This official document describes the various steps that need to be followed to ensure effective Basement Tanking and Basement Drainage.

The first step is to determine to what use the basement will be put. BS8102 describes four standards of tanking and waterproofing, 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 structure and it's waterproofing materials will be subjected to.

Only when these factors have been considered can the design of the system and the type of materials be selected. Although in theory the selection and design sounds a relatively simple task, there are many decisions to be made.
