Penetrating concrete waterproofing and protection for every concrete surface — not just floors. Parkades, transit stations, university campuses, municipal buildings, retaining walls, and exterior facades. The same systems used on the Canada Line, EverGreen Line, Canada Place, and Pacific Centre.
Every concrete surface — vertical walls, columns, parking decks, transit structures, building exteriors, underground infrastructure, retaining walls — is subject to deterioration from water infiltration, chloride penetration, carbonation, freeze-thaw cycles, and chemical attack. Left unprotected, concrete deteriorates. Protected correctly, it lasts for generations.
Our penetrating concrete waterproofing systems chemically react with the concrete matrix to create a hydrophobic barrier within the pore structure — not a coating on top. The result is permanent, internal protection that cannot peel, delaminate, or wear off. Applied with WashAway Xtreme preparation, DualGuard absorption takes 1–2 hours and the surface is immediately back in service.
We use Protocol Environmental Solutions' DualGuard and VersaGuard systems — the same products used on BC's most demanding concrete infrastructure projects.
Every concrete protection project follows the same proven two-step process. Step one prepares the surface. Step two permanently protects it.
Applied to the concrete surface to clean, degrease, remove efflorescence, and profile the surface to CSP 1–4. Opens the pore structure of the concrete to ensure DualGuard can penetrate to its full depth. The preparation step that makes the protection permanent.
Sprayed onto the prepared surface with liberal coverage. Penetrates 1–3mm into the concrete matrix and reacts chemically to create a permanent hydrophobic membrane inside the concrete itself. The surface is left for 1–2 hours for full absorption. No topcoat, no colour, no visible change — just permanent internal waterproofing. ASTM C-1315 compliant.
We work with GCs, engineers, property managers, and government clients. Fast to mobilize, minimal disruption, permanent results.
