GRC Columbia distinguishes itself by having management and trades persons who have dedicated themselves to the waterproofing industry for over 30 years. It is our knowledge and commitment to this specialized craft that enable us to provide our clients with the highest quality waterproofing services available.

Rubberized asphalt waterproofing (aka: hot rubber) is a monolithic, fully bonded roofing and waterproofing membrane commonly found in high-rise roofing, as well as parkade roof slab systems. The membrane is hot applied and then reinforced with a polyester fabric and protection board. Upon cooling the system can be built up in a variety of ways utilizing insulation, paving stones, Traditional ballast or vegetation. Rubberized asphalt remains the cornerstone of our waterproofing operations, due in part to the superior versatility and protection provided by hot rubber over other waterproofing systems.

Rubberized Asphalt waterproofing is available in a LEED compliant, green conscious product that contains 25% post-consumer recycled material.
