Waterproofing systems from Triton were specified for a luxury mews development in London by R & D Management – specialist waterproofing advisors and surveyors. The project included a twin level basement constructed from insitu reinforced concrete.
Given the type and form of construction, and its intended use, a BS 8102 2009 Type C system (cavity drain membranes) was specified as the most appropriate method of waterproofing.
However, to provide additional waterproofing protection and as an anti-lime coating to the cavity drain membranes, Triton’s TT Vapour Membrane was applied to the entire basement (walls, floors and soffits). TT Vapour Membrane is designed as a fast drying waterproof and gas proof membrane which is supplied as a ready blended coating which can be applied by brush, roller or spray.
The cavity drain membranes were installed by waterproofing specialists, Renlon Ltd, who fitted Platon Multi to all walls and Platon P20 to the lower basement floor.
Both types were supplied by Triton.
Cavity drain membranes work on the principle of allowing any water to continue to penetrate the structure but control it in the air gaps between the studs and divert it to a suitable drainage point.
They do not allow pressure to build up against the internal construction. They are loose laid on floors and fixed to walls using special plugs and sealing materials.
Once fitted the wall surfaces can be dry lined or plastered directly and floors can be screeded or a dry board system installed. Drainage was provided by Triton’s Aquachannel, a conduit fitted around the perimeter of both upper and lower basement levels and linked through the upper basement floor slab by a series of downpipes.
Rodding points were located within the Aquachannel to provide access to maintain and test the system. Any water entering the Aquachannel system is directed to a sump in the lower basement containing two mains powered pumps which are controlled by Triton’s Dual Assist Control Panel. On completion, the system was fully flood tested to ensure all details had been designed and installed correctly and performed as per the specification.
