ARDEX WPM 120 is an APP (Atactic Polypropylene) plastomeric-type modified bitumen waterproofing membrane for use as the mid- or base-layer in a multi-layer bituminous roofing system.
ARDEX WPM 120 consists of a specially formulated bituminous compound of distilled asphalt modified with selected high-grade visco-elastic polymers and reinforced with a combined reinforcement carrier. ARDEX WPM 120 is coated with a sanded top surface finish, while the bottom surface is embossed and protected by a heat sensitive polythene film.
ARDEX WPM 120 is used as a base and or mid-layer in multi-layer membrane systems in horizontal or vertical applications for waterproofing balconies, terraces and roofs. ARDEX WPM 120 membrane must be protected from UV.
