This extremely effective system utilises an ‘egg box’ style design, cavity drainage membrane. The membrane allows any water penetrating through the fabric of the building, to flow in a controlled manner behind the final wall covering, into concealed irrigation channels and thereafter into a sump. The water is then pumped into standard drainage exits.

This is an area of work where we are very proud and confident in our achievements and we therefore offer a 20 year guarantee.

In addition to our extensive experience, our confidence is based on the fact that we are authorised and recommended by Triton Ltd., the premier Cavity Drain Membrane waterproofing system manufacturer in Britain.

It is further demonstrated by our continued employment for this type of work, with construction giants such as Northwest Holst and Mansell.
