Overview

Welded watertight. Engineered for large-span roofs.

PVC Waterproofing Membrane is a polyester-reinforced plasticized polyvinyl chloride membrane designed for single-ply mechanically fastened roof systems. Seams are hot-air welded on-site to create homogeneous watertight joints with strength equal to the parent membrane.

Preferred for large-span commercial roofs, podium decks, and water-feature applications, with certified welding required for warranty-grade installation.

Key Features

  • Polyester-reinforced for dimensional stability
  • Hot-air welded seams – homogeneous bond strength
  • Inherent fire resistance – Broof(t1) rated
  • Root-resistant for green-roof applications
  • Reflective light colours reduce heat gain
  • Compatible with insulation boards above and below
