ARDEX WPM 1000 RR - Weldtec Root Repell Membrane

Product Description

ARDEX WPM 1000 RR is a high-performance, single-ply waterproofing membrane designed for use in areas susceptible to root damage. The membrane contains a premium root inhibitor that repels root growth without killing the root. It is designed primarily for areas covered with, or exposed to soil and plants. Once installed, ARDEX WPM 1000 RR will remain a permanently flexible waterproof lining and bond to most building surfaces.

ARDEX WPM 1000 RR is one of the WeldTec range of membranes which are heat-welded at laps and seams to create a superior bond, consistent gauge and allow a quick installation. ARDEX WPM 1000 RR has excellent flexibility, durability, and superior resistance to tearing, cracking, bubbling and absorption.
