Concrete Waterproofing Type A Brochure



Concrete Waterproofing Type B Brochure


Type C waterproofing is defined in BS 8102: 2009 as ‘drained protection’ which is achieved by the incorporation of a drained cavity within the basement structure. The basement wall must provide enough primary resistance to water ingress to ensure the cavity only accepts a controlled amount of water or dampness. Water is collected in the cavity between the external wall and an internal lining (cavity drain membrane) and diverted to a suitable drainage point.

Triton supplies a comprehensive range of pumps and drainage components designed to complete a fully drained waterproofing system. More information is available here.

The use of cavity drain membranes does not allow pressure to build up against the internal construction and the air gap allows the structure to breathe - and to some extent to dry out. Cavity drain membranes are loose laid on floors and fixed to walls using special plugs and sealing materials, with little or no preparation required to the substrate. Once the membrane has been fitted, wall surfaces can be dry lined or plastered directly and floors can be screeded or a floating dry board system installed.
