For use in mechanically fastened single-ply waterproof systems.


A homogeneous PVC membrane, without any polyester fabric carriers, for use in mechanically fastened single-ply waterproof systems.

Features and benefits:

  • Highly resistant to ageing and industrial pollutants and requiring no surface treatment or maintenance throughout its service life.
  • The absence of carrier within the membrane enables the natural flexibility and extensibility of the membrane to absorb any movement of the roof.
  • The membrane also absorbs some of the dynamic wind loads applied to the roof, so reducing the loads transferred to the fasteners.
  • The membrane is fastened with Sika-Trocal metal discs or proprietary pressure plates, secured with thermally broken fasteners.
  • Laps are sealed with THF welding agent, with hot air sealing used at details.
