Scope of Use

ARDEX WPM 114 is used as part of a multi-layer system in roofing applications for waterproofing. It has been designed to be used in situations where there may be potential moisture issues in the substrate and can only be used as the base sheet of a multi-layer roofing system.

  • Virtually eliminates bubbles and blisters forming underneath the waterproofing layer.
  • Allows vapour permeating through the deck to diffuse underneath the waterproofing where, ideally, ARDEX Low Rise vents should be installed to allow the vapour to escape to the atmosphere.
  • Eliminates the creation of stresses in the waterproofing layers thus greatly reducing failures in the waterproofing caused by deck movements.
  • Is the ideal solution for controlled, partially attached first layer in a multi-layer system.
