FAQ’s  – Basement Damp Proofing

What is the process?

Tapco HomeDry is Delta Membrane and Sovereign approved contractors and install Cavity Drain and Ventilated membrane systems to walls and floors, in accordance with BS8102:2009. These are high-density Polyethylene, studded membranes that are loose laid over the floors and fixed to walls and ceilings, using ancillary waterproof plugs and tape. Depending on the type of membrane we use, these can either be plastered directly onto or dry-lined. The system is likely to include a special drainage channel, sump and pump, which will discharge any moisture that enters behind the membrane, into the sump. This is the pumped out to an external drain, chosen by us. Alternately, we can sometimes use natural, gravity drainage. When the installation is completed, the floor can be finished with a floating, pre-treated, tongue and groove floor or a concrete floor screed to complete the system.

Slim-line Cavity Drain and Ventilated Membrane systems may also be used in some places, which can also be plastered or dry-lined.

Tanking below ground

Tapco HomeDry also specialises in Structural Water Proofing, known as Tanking, which can be applied to both walls and concrete floors. Our experienced technicians first prepare the walls,
create a channel and floor/wall joint and apply a gauged scratch coat of waterproof rendering, in preparation for Tanking.

Once dry, pre-mixed slurry coats of a cementitious structural waterproofing system are then applied, allowing each one to cure, before applying the next. Further damp proof rendering and plastering is then carried out, all of which blocks further damp from penetrating the floor or wall.
