FortisMate PWM Series
FortisMate® PWM-SAB is a high-performance bitumen-based pre-applied self-adhesive waterproof membrane, designed specifically for underground pre-applied waterproofing projects. It uses polyester non-woven fabric as the carrier, impregnated and coated with polymer-modified bitumen, finished with a sand anti-adhesive layer on the top and a release liner on the bottom.
The membrane bonds permanently with post-cast concrete, forming a skin-type waterproof system that eliminates water channeling. It offers excellent self-healing, high tensile strength, and strong puncture resistance.
Highlight: PWM: Pre-applied Waterproof Membrane；SAB: Self-Adhesive Bituminous
Scope of Application
• Metro & tunnel structures
• Underground pipe galleries
• Foundation pits
• Pre-applied reverse-adhesion waterproofing for concealed excavation
