Cavity Drain Membranes

Cavity Drain Membrane System (Type C) is a cavity that is formed between the ground retaining elements, and the internal finishes of a structure. These cavities are used to direct water to collection channels, that in turn deliver water to a point where it can be discharged.

This process of water management is generally achieved by the use of cavity drain membranes (CDM) and drainage channels, or pipes directing to a sump and pump system to manage the disposal of the collected water

TK Waterproofing Solutions can offer bespoke design, PI insurance, an insurance backed warranty, and a pump maintenance programme on all CDM projects.
