A showroom-grade finish, 3× harder than epoxy, installed in 1–2 days and backed by a 5-year warranty — throughout Saint-Eustache and Greater Montreal.
★★★★★ 57 verified 5-star reviews
Saint-Eustache blends a historic riverside core with residential neighborhoods and an agricultural fringe near the Lac des Deux Montagnes. Garages here run from older slabs to protect to recent builds worth sealing early.
River humidity, farm grit and winter salt all wear bare concrete. Our polyaspartic coating seals against moisture, resists de-icer and oil, and delivers an anti-slip finish that cleans in minutes.

All our systems are polyaspartic-based: harder, faster to install and UV-stable, unlike traditional epoxy.
The #1 choice for garages: decorative chips, a slip-resistant finish and dozens of color blends.

In the low-lying parts of Saint-Eustache, near the Rivière du Chêne and the Mille Îles, the first thing we look for is a white powdery bloom on the slab. That is efflorescence: mineral salts carried up through the concrete by groundwater and left behind as the moisture evaporates at the surface. It matters because it is not dirt — it is evidence that water is moving up through the slab, and any coating applied over it will be pushed off from underneath. We remove the deposit, test the moisture that caused it, and spec accordingly rather than painting over the symptom.
The mix runs from older Vieux-Saint-Eustache singles at $2,499.99 to newer family builds in the 300–450 sq ft range with storage, which is the $3,249.99 package.
