ARDEX WPM 116

ARDEX WPM 116 is an A.P.P. (Atactic Polypropylene) Plastomeric type modified bitumen membrane slip or base sheet, consisting of a specially formulated bituminous compound of distilled asphalt modified with selected high grade visco-elastic polymers. The product is reinforced with a combination of fibreglass and non-woven polyester. ARDEX WPM 116 top surface is embossed and protected by a heat senstive polythene film. This type of finish for the top surface has been chosen for two specific purposes.
1. To act as a temperature gauge during application. When the film melts it shows that the compound is at the correct temperature.
2. The embossing is to allow the gases to rapidly escape when heated to its correct installation temperature avoiding possible
problems of bubbling and blistering, due to gases being trapped between the slip or base sheet and the membrane subsequently applied on top.
