Profiled cavity drain membranes have an ‘egg-box-like’ shape to form a continuous air gap or drainage channel; they are often used to control dampness in existing buildings.

Twistfix Damp Proof Membranes feature:

• Isolate plastered and decorated finishes from damp walls and salt contaminated masonry
• Are robust, durable with a life expectancy greater than 50 years
• Are quick and easy to fit
• Have an optional mesh face that provides a key for plasterboard adhesive or cement render
• Are available with; stand-off' stud sizes ranging from 2mm to 8mm

Air-gap membranes are particularly useful in projects that require water­pro­ofing of cellar walls and floors, protecting wall sufaces against lateral damp penetration and allowing the immediate rein­sta­tement of plastered finishes following treatment of rising damp problems.
