Sika-Trocal S

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