Fluid-Applied Waterproofing

Single-component, cold-applied waterproofing system. It will not crack in extreme cold or flow due to softening at high temperatures. It is suitable for use on all exterior concrete surfaces, where protection from water intrusion is desired. Designed for use on backfilled walls, primarily on concrete.

Sheet-Applied Waterproofing

Waterproofing membrane that is self-healing, self-sealing and self-repairing. It has three active layers – a watertight EPDM barrier, an active core with the ability to seal when penetrated and an active barrier which seals the overlap and helps resist lateral movement of water. Also, a non-woven fabric layer promotes the mechanical adhesion of the membrane to the concrete and masonry walls.

Bentonite Clay Membrane

Dual layer waterproofing consisting of virgin HDPE, sodium bentonite, and a protective layer consisting of a non-woven polypropylene. The HDPE provides the first layer of waterproofing, while the bentonite’s self-sealing capabilities ensure positive puncture protection under hydrostatic conditions. The polypropylene fabric protects the bentonite from direct installation of shotcrete.
