ARDEX WPM 1000 (20m x 1.4m)

*To be installed by certified installer*

ARDEX WPM 1000 Weldable Waterproofing Membrane is a high-performance synthetic rubber membrane designed for versatility and durability. This heat-weldable solution is ideal for waterproofing underground tanking, rooftops, decks, undertile areas, and canal or pond linings. Its synthetic rubber composition is specifically engineered to resist aging from heat, sunlight, and ozone.

Featuring polypropylene filaments welded to both sides, ARDEX WPM 1000 ensures superior wetting by water-based adhesives. This membrane remains flexible at low temperatures and offers excellent gas impermeability. Laps and corners are heat-formed or welded for a seamless finish. Tiling can commence just 60 minutes after installation using standard ARDEX adhesives like X18.
