ARDEX WPM 1000 (20m x 1.4m) | WPD Group

*To be installed by certified installer*

ARDEX WPM 1000 Weldable Waterproofing Membrane is a versatile rubber membrane that can be heat welded. It is suitable for waterproofing underground tanking, rooftops, decks, undertile, canal and pond linings. ARDEX WPM 1000 is made up of synthetic rubber with properties which resist ageing from heat, sunlight and ozone and is heat weldable.

Polypropylene filaments are welded onto both sides of the membrane for better wetting by water based adhesives. It has excellent gas impermeability and toughness and remains flexible at low temperatures. Laps and corners are to be heat formed and/ or welded. Tiling can be done directly on the membrane after 60 minutes with common ARDEX tiling adhesives like X18.
