Concrete protection

Waterproof Membrane Systems

Protection that goes beyond the finished surface.

A floor may need to do more than resist wear. In parking structures, mechanical rooms and wet areas, the flooring assembly may also be required to limit water entry and protect the concrete or spaces below.

East Coast Coatings installs compatible membrane and protective coating systems selected for the exposure, substrate and service conditions.

A complete waterproofing assembly

A traffic-bearing system may include a suitable primer, an elastomeric membrane, an aggregate-containing wear layer and a protective finish. Each component has a different role: bonding to the substrate, providing waterproofing, accommodating specified crack movement or resisting surface wear.

A protective topcoat alone should not be assumed to provide the same function as a dedicated waterproofing membrane.

Match the protection to the traffic

Parking stalls, drive aisles, turning areas and ramps experience different wear. A single parking structure may therefore require different wear-layer builds or aggregate treatments while maintaining continuity of the waterproofing system.

For interior areas, selection also depends on cleaning practices, spills, equipment and the proposed floor finish.

Pay attention to the connections

Drains, cracks, joints, curbs, penetrations and wall-to-floor transitions require appropriate details. These connections are part of the waterproofing design, not simply finishing touches after the main floor is complete.

Crack-bridging capability is limited to the selected system's design. Moving joints and structural concerns need their own treatment; a coating should not be expected to resolve them automatically.

Typical applications

Parking decks, ramps, mechanical and equipment rooms, wash areas and other concrete spaces where a specified waterproofing assembly is required.

Is this the same as treating moisture in the concrete?

No. Managing water on the surface and managing moisture within or beneath a slab are different requirements. Moisture conditions need to be assessed before choosing the membrane, primer or any separate moisture-control treatment.
