Frequently Asked Questions

Can you fix cracks in my garage floor?

Yes. Garage floors often crack due to settling or freeze-thaw cycles. We chase the crack (open it up with a diamond blade), fill it with a polymer-modified repair mortar or epoxy, and grind it flush for a smooth finish.

Will the crack come back?

If the foundation is still actively settling, a rigid repair might re-crack. In these cases, we use flexible sealants that allow for slight movement while maintaining a waterproof seal. We assess the stability of the slab before starting.

Is this the same as waterproofing?

Crack injection is a specific type of interior waterproofing. It stops water from entering through that specific void. If you have widespread dampness, we may recommend a broader solution, but for specific leaks, crack repair is the most cost-effective method.

Requires inspection: Yes
Estimated Time: 3 to 8 hours
Materials included: Not included (unless specified)
Warranty Period: 2 years
Service Complexity Moderate

Why is a Technical Visit necessary?

Not all cracks are created equal. A "hairline" crack might be simple shrinkage, but a horizontal crack in a foundation wall could indicate serious hydrostatic pressure or structural failure. Using a simple tube of caulk from a hardware store is a temporary band-aid that doesn't stop water pressure. Our Crack Foundation & Concrete Slab Repair assessment measures the width and depth of the crack to determine if it needs low-pressure epoxy injection (for strength) or flexible polyurethane foam (to stop water leaks).
