The Solution

As the wall surfaces were painted and would require substantial preparation work before a cement based tanking system could be used, it was decided to use a cavity-drain plastic membrane system.

Design Features

As the basement already had a drainage system, it was possible to link them to the drains within the tanking system removing the need for a sump or pump.

The restricted width of the basement meant that a metal stud wall had to be kept tight to the wall membrane.

Two extractor fans with humidity sensors controlled relative humidity within the basement.
