Comprehensive waterproofing solutions

Created from a cell mesh, bonded with a blended polyethylene/polypropylene membrane, FOSROC waterproofing membranes were initially designed for construction projects with piled walls, or where ground settlement was likely.

This unique waterproofing product fully adheres to structural concrete – and withstands ground settlement, dirt and grime.

FOSROC waterproofing products are a good choice for sites likely to be affected by rainwater, groundwater or contaminants within the soil. And we frequently choose FOSROC products for our customers who need concrete spalling or patch repair works.

Danrae Group’s expert waterproofers have used FOSROC products for major construction clients including ANSTO (Australia’s Nuclear Science and Technology Organisation).
