It can support a dry lining, screed or flooring, in the following situations:

• On damp walls and floors in underground situations subject to high groundwater levels, and perennial moisture.
• On vaulted ceilings of archways or cellars subject to water ingress.
• In conjunction with a remedial dip system where the walls and floors have a high salt content, and/or it is necessary to complete the installation immediately without allowing a period for initial drying.
• Over walls and floors which have a friable or painted surface, are contaminated (e.g. with oil or mould), or have a high salt content.
• As a structural waterproofing membrane in areas subject to vibration.

Depending on the application required and the site conditions, the membrane may be used as:

• An underfloor damp-proof membrane.
• A dry lining for walls, ventilated into the room via aeration slots at the top and bottom of the wall or via passive air vents, where access through an external wall is available.
• A sealed system covering wall, floor and ceiling with provision made for disposing of water build-up behind the membrane via a sump and pump.
