Basement Membranes

When looking to waterproof a basement, the most reliable way is to install a cavity drainage system with cavity drain membranes.

Cavity Drain Membranes

Basement waterproofing membranes like our PermaSEAL&reg range and those manufactured by Newton and Platon are designed to control the passage of water using cavity forming membranes, drainage channels and sump and pump systems.

Drainage membranes have a stud profile that allows any water to be channelled down and evacuated to the outside of the property into a drain or natural drainage point.

If you want to ensure that water ingress is controlled in your basement, there are two main types of membrane:

Waterproof Membranes for Walls

Wall membranes are used to control water ingress in your basement as part of a cavity drainage system. These interior basement waterproofing membranes are fixed on retaining walls to provide Type C drained protection from water ingress. They are easy to fix with membrane quick plugs. Browse our membrane fixing plugs. These membranes are used along with a drainage system as described above to ensure that any water is evacuated safely, leaving the basement dry and free from damage.

Some wall membranes have a mesh welded on the face for direct rendering or dot and dab finishing.

Many wall membranes with 8mm stud can also be used as flooring membranes.

Floor Membranes

Basement floor membranes can be used for isolating moisture sensitive flooring from dampness in the floor slab and as part of a basement waterproofing system.
