CAVITY DRAIN MEMBRANES

The cavity drain membrane system is a special high-performance polyethylene membrane which is extruded into a series of studs. These studs create an air gap behind the waterproof membrane. A welded mesh on the front of the membrane improves the bonding efficiency of the plasters and renders for dry and durable finishes.

The cavity drain membrane is watertight; resistant to high and low temperature extremes; chemically resistant to acids, alkalis, oil and solvents; and is approved for use in drinking water applications.

The membrane stud design provides a continuous air gap which isolates the damp wall from the new plaster and decorative finishes. It also improves ventilation of the wall, allowing for permanent dampness control.

Unlike conventional cementitious tanking systems, which hold the water back, cavity drain membranes allow water to penetrate the structure but control it in the air gap before rerouting it to an appropriate drainage point.

This system utilises an ‘egg box’ design. The membrane maintains the flow of any water penetrating the fabric of the building, behind the final wall covering, and directs it into hidden irrigation channels and a sump before it is pumped into standard drainage exits.

The cavity drain membrane system can improve the functionality of your basement or cellar build. 
SUMP PUMPS
In properties that have been flooded or are at risk of flooding, a submerged sump pump would be installed below floor level to collect water penetrating through the walls/floor and pump it outside to an external drain.

The damp proof membranes that are used have moulded studs on the reverse side to give clearance between the membrane and wall/floor to allow water to drain away freely.

It is important that when the waterproofing system is designed for your property suitable ventilation is considered, i.e., natural ventilation or an extractor fan or other appropriate ventilation equipment. Without these measures being fully considered, condensation is likely to occur.

The work is completed with the floor having a concrete screed or tongue and groove flooring installed and the walls having plasterboard and skim applied. This solution will provide a dry internal floor and wall surface, making the cellar or basement rooms of your property habitable again.

The above membranes can be used on properties where the walls are above ground but have been subject to major flooding. This allows the property to be re-occupied sooner than the normal drying periods allow. We are also able to offer cementitious tanking as an alternative damp proofing solution.
