Drainage and Protection Systems

Hydroduct® drainage composites give construction professionals a high performance, prefabricated drainage media that is designed to retain soil while allowing water to collect and pass through to its core, and away from your building. In addition, they provide lasting protection to the waterproofing membrane system.

Roofing Underlayment and Self-Adhered Flashing

The popular Grace Ice & Water Shield® is a sloped roof underlayment which provides a highly effective barrier against leakage resulting from ice dams or wind-driven rain. Similarly the GCP Vycor® self-adhesion flashing systems are the products of choice for sealing leaks around windows, doors, corner boards, sills or anywhere there is an opening or area susceptible to water, air and moisture penetration.

Sheet Applied Membranes

Waterproofing applications such as for foundation walls, plaza decks, parking and bridge decks, tunnels, interior slabs, planters, laboratories and mechanical rooms and balconies, the popular GCP BITUTHENE® membranes are applied to the positive side of structures to stop water before it hinders the structural elements of a building. For Blind Side waterproofing applications, Preprufe® Plus waterproofing membranes form a continuous mechanical bond to concrete that is cast against it. These membranes are installed against soil retention systems or applied over mud slabs or compacted soil before the concrete structure is poured. Applications include foundation walls, under slabs and tunnels.
