Garage floor repair & coating, Ottawa

Repairing spalled areas and coating an existing slab starts from $11/sq ft. If the slab itself has settled or cracked through, a full break-out and repour — new compacted gravel base, reinforced concrete — for a typical 2-car garage usually runs around $6,000, depending on access and disposal.

No — coating over an uneven, cracked or settled slab just hides the problem and can even be slippery once wet. Repair or level the concrete first, then coat. A sealed, properly sloped floor is what actually stands up to a winter's worth of salt brine dripping off your car.

Brine dripping off a car overnight is more concentrated and aggressive than road salt spread on a driveway, and it sits in one place instead of washing away. That's why garage slabs pit and flake years before a driveway does — a sealed, sloped floor is the fix.

Both are salt- and abrasion-resistant options we apply after diamond-grinding for a mechanical bond. Polyaspartic cures faster — often usable within a day — and holds up slightly better to UV and hot tires; epoxy is a proven, lower-cost option. We'll recommend one based on your timeline and budget.
