Why basements need a different approach
A garage floor and a basement floor look similar once they're coated, but the concrete underneath behaves differently. Calgary's clay-heavy soil and high water table mean below-grade slabs can carry moisture that isn't visible to the eye — coat over that without checking, and even a well-applied epoxy can blister or delaminate months later. Every basement job starts with a moisture test, not just a sweep and a coat.
Once the slab checks out, the process is similar to a garage: grind or prep the surface, base coat, flake or solid colour broadcast if you want one, and a sealed top coat. The result is a floor that's easier to clean, doesn't shed concrete dust, and holds up to a finished or semi-finished space.
What's included
- Moisture testing before anything is quoted
- Crack assessment and repair where needed
- Surface prep matched to your slab's condition
- Solid colour or flake-broadcast finish, your choice
- Sealed, easy-to-clean top coat
- Written flat-rate quote before any deposit
Final price depends on slab condition, crack repair needed, and finish chosen — confirmed in writing at your on-site quote.
Unfinished basement? Still worth it
A lot of Calgary basements sit unfinished for years with bare concrete underfoot — cold, dusty, and hard to use for anything but storage. Sealing that slab now, even before you finish the rest of the space, keeps concrete dust down and gives you a clean, usable floor in the meantime. It's one of the more overlooked upgrades for a basement that's "someday" going to be finished.
Basement floor FAQ
Does my basement need a moisture test? +
Yes. Calgary's clay-heavy soil and high water table mean basement slabs often carry more moisture than they look like they do. We test before quoting, since a coating applied over a damp slab can fail regardless of installation quality.
Do I need a permit? +
Usually not for a floor coating alone, but larger below-grade renovation jobs may need a City of Calgary permit depending on scope — we'll flag that during the assessment.
Can you coat an unfinished basement? +
Yes — bare, unfinished basement concrete is one of the more common jobs we do. It seals the slab and cuts down on concrete dust whether you finish the rest of the space now or later.
