Deck & Balcony Waterproofing in the Lower Mainland, BC

BC rain doesn't stop — and neither does the damage it causes to unprotected decks and balconies. We install durable, slip-resistant waterproofing systems for residential decks, commercial balconies, and parkade surfaces across Metro Vancouver.

Why Decks Fail in BC

Your Deck Takes the Full Force of BC Weather

Decks and balconies are among the most exposed parts of any building. In the Lower Mainland, they face over 1,150mm of annual rainfall, UV exposure, freeze-thaw cycles, and constant foot traffic. Without proper waterproofing, water infiltrates the deck structure, causing rot, mold, and damage to the space below.

The most common failure points are flashing at walls and posts, drain connections, and surface cracks. Once water gets under the surface, the damage accelerates quickly — and repairs become significantly more expensive.

Our Systems

Deck Waterproofing Solutions We Install

From residential balconies to commercial parkades, we have the right system for every application and budget.

Liquid-Applied Membranes

Seamless, flexible membranes applied by roller or spray. Ideal for residential decks, balconies, and irregular shapes. Available in multiple colors and textures.

Sheet Membranes

Pre-formed waterproof sheets bonded to the deck surface. Excellent for large flat areas and commercial applications requiring consistent thickness.

Traffic-Bearing Systems

Heavy-duty systems designed for vehicle traffic in parkades and commercial parking areas. Withstands vehicle loads, de-icing salts, and freeze-thaw cycles.

UV-Resistant Coatings

Topcoats that protect the waterproofing membrane from UV degradation, extending system life and maintaining appearance.

Drain Installation & Repair

Proper drainage is critical to deck waterproofing performance. We install, repair, and reposition drains to ensure water flows away from the structure.

Flashing & Edge Sealing

Transitions at walls, posts, and edges are the most common failure points. We install proper flashing and edge details to prevent water infiltration.
