ARDEX WPM 117 - Self-Adhesive Bituminous Base Sheet

Product Description

ARDEX WPM 117 is a self-adhesive, fibre-reinforced SBS bituminous membrane. ARDEX WPM 117 is cold-applied and installed without the use of naked flames, and self-seals on contact if being installed using nails or other fasteners, or if cut accidentally. It is generally used as a base layer over heat sensitive substrates as part of the ARDEX Bituminous Roofing System.

ARDEX WPM 117 resists elongation and mechanical stresses like no other system or waterproofing material can. ARDEX WPM 117 has assured versatility because of its softness, lightness and flexibility. In situations where traditional torch-on or fastened systems cannot be used, ARDEX WPM 117 provides the best results without compromising the quality of the work to be done.
