PVC waterproof membrane with glass fibre reinforcement for ballasted applications.
PVC waterproof system for use on ballasted roofs.
- Upper protective layer:
S-Felt T 300:
A separation, levelling and protection layer made of polyester (PES).
- Sika-Trocal® SBV:
A protection and separation layer made of polyester (PES) fleece with a PVC-P coating on one side. The fleece free edge is 5–15 mm wide.
- Waterproof membrane:
A PVC membrane, with glass fibre reinforcement, for use in ballasted single-ply waterproof systems. The membrane contains biocides and is highly resistant to ageing, to industrial pollutants and to the bacteria that flourish in the moist layer of dirt present immediately above the membrane in ballasted roofs. It requires no maintenance throughout its service life.
The membrane is restrained by the weight of ballast, although under timber decking additional restraint such as Sika-Trocal metal discs or proprietary pressure plates may be required.
Laps are sealed with THF welding agent, with hot air sealing used at details.
- Vapour control layer:
A 0.15 mm thick, polyethylene based, vapour control layer. S-vap 500E is manufactured from low density polyethylene, blended to produce a vapour control layer that is flexible when cold, resistant to chemicals and ageing and rot proof. It is suitable for use in most mechanically fastened systems using the Sika-Trocal PVC membranes only. Not suitable for high humidity applications or under green roofs.
