STRUCTURAL REPAIR
CONCRETE CRACK REPAIR
FIX THE CRACK, NOT JUST THE SURFACE.
A crack in a concrete slab or wall isn't cosmetic — it's a sign the concrete has already moved. Painting or topping over it just hides the problem until it reopens, usually right through whatever finish was put on top. Injection repair fills the crack through its full depth, from one face to the other, so the fix holds regardless of what goes over it afterward.
We treat crack repair as the prep work it actually is. Most jobs happen right before a new epoxy or PU floor goes down — injecting a crack after the new floor is installed defeats the point, so it's step one, not an afterthought.
- Epoxy injection restores structural strength in load-bearing cracks
- Polyurethane (PU) injection seals active leaks and moving cracks
- Full-depth fill, not a surface patch
- Often the first step before a new flooring system goes down
TWO INJECTION METHODS
Which one's right depends on whether the crack is moving and whether water is getting through it.
Epoxy Injection
For structural, non-moving cracks. Cures rigid and bonds to the concrete on both sides, restoring the slab's original load-bearing strength. The right call when the crack isn't leaking and isn't expected to move again.
Polyurethane (PU) Injection
For active leaks or cracks that still move with temperature and load. Cures flexible and expands to seal water out even as the crack shifts slightly. The standard choice for basements, retaining walls and anywhere water is getting through.
Before New Flooring
Any crack in a slab gets injected and confirmed stable before an epoxy or PU floor goes down over it — the same substrate check as our moisture testing, just for movement instead of water.
