Externally, two coats of TT Vapour Membrane were applied to the entire wall area extending below internal floor level to the base of the wall/foundation level. Internally, two coats were applied to the new floor slab, returning up the walls to beyond the new damp proof course. The new DPC was created using Triton Injection Mortar which also improved the impermeability of the wall to ground gas migration. A perforated sub floor drain under the slab was linked to Triton’s Ground Gas Fan which was fitted and vented externally.

Triton TT Vapour Membrane is an elastomeric, ready blended coating that acts as a bonded waterproof barrier against Radon, Methane and Carbon Dioxide. It can be applied to concrete, masonry and brick substrates by airless spray, roller or brush.
