Concrete Crack Repair & Substrate Restoration in the GTA
Substrate repair before or instead of coating — crack filling, structural patching, self-levelling, and spall repair.
What is Concrete Repair & Restoration?
A coating is only as good as the slab under it. Cracks that move, spalls that haven’t been patched, and slabs that are out of plane are the most common reasons epoxy floors fail — and most contractors skip this step to keep the quote low.
We don’t. Every coating quote includes the substrate repair the slab actually needs, so the floor we install lasts the full warranty. It’s why we’re trusted as Toronto’s full-spectrum epoxy flooring contractor — the prep is never an afterthought. Concrete repair is also a stand-alone service for owners who want raw concrete restored without a coating system on top, and it’s the first step in most epoxy floor repair and recoat jobs.

Concrete Repair FAQs
Do I need concrete repair before epoxy?
If you have visible cracks, spalls, oil-saturated areas, or uneven slabs, yes. Coating over damaged concrete is the most common reason floors fail in 2-3 years. We include the necessary substrate repair in every quote so there are no surprises.
Can you fix a slab without coating it?
Yes. Concrete repair is offered as a stand-alone service for slabs that aren't getting coated — common for warehouse floors, exterior pads, and basement slabs where the owner wants raw concrete restored.
Will the cracks come back?
Stitched and properly filled cracks don't propagate. Carbon fiber staples bridge the crack, and the polyurea fill stays flexible. We won't just smear filler over a moving crack and walk away.
How long does substrate repair take?
Depends on damage extent. Small crack repair is hours; full self-levelling underlayment on a large slab is a full day plus cure time.
Can you fix sloped or sunken slabs?
Yes — self-levelling underlayment can correct slope and minor settlement. Severe structural settlement needs separate engineering.
