Waterproofing & Deck Coating
Liquid-applied membranes for balconies, walkways and plaza slabs — designed around Vancouver rainfall, standing water and the movement of an exterior deck.
04 · Protection- Water staining on the ceiling below a deck
- Cracked or peeling deck coatings
- Ponding water on balconies and walkways
- Exposed plaza slabs over occupied space
- Failed sealant at posts, drains and edges
Flexible membranes, detailed at the edges.
Elastomeric, seamless and flexible enough to move with the deck. The standard for pedestrian decks in a wet climate.
Faster cure and UV stability for exposed decks or where the space needs to be back in use quickly.
Used beneath the membrane for bond and for filling cracks and spalls before the system goes on.
- 01Assess substrate and exposure
Moisture, slope, drainage and the condition of the concrete underneath the current coating.
- 02Prepare and detail
Grinding or removal of failed coating; cracks, drains, posts and edges detailed first.
- 03Membrane base coat
Liquid-applied membrane built to the specified thickness.
- 04Wear coat and texture
Slip-resistant wear surface and topcoat, then cure before use.
Balconies, walkways, plaza slabs, roof decks, stair landings.
It depends on exposure, foot or vehicle traffic, moisture and the condition of the substrate. Polyurethane, polyaspartic and epoxy systems each have a place; we recommend based on those factors.
Proper surface preparation — typically mechanical grinding — is what allows a coating to bond. Skipping it is the most common reason coatings fail early.
Start with the concrete.
Fix it properly.
