NORTH LONDON

Diagnosis
This large rear basement extension was suffering from water damage – penetrating from the roof, from the earth retaining walls and internally condensing from the swimming pool onto un-insulated surfaces. The intention was to extend the basement to create a fitness and plant room.

Solution
Stonehouse designed and installed a new Acriflex Winter external waterproofing system to the roof terrace. This was combined with a full internal cavity drain membrane system with two sump chambers. Stonehouse also insulated the soffit by the specialist application of Foamglas insulation.
