Basement Floor Crack Repair in Ann Arbor, MI
Basement floor crack repair means cleaning out, preparing, and filling cracks in your concrete slab to stop them from widening or letting water in. Floor cracks are common in Michigan basements because the clay-heavy soil expands and contracts significantly with moisture changes. Not all floor cracks are structural emergencies, but ignoring them lets water and vapor into your living space. We determine what's behind the crack before we fill it so the repair actually holds.

When to Call
When You Need Basement Floor Crack Repair
- You notice water seeping up through a crack after heavy rain or snowmelt

- Efflorescence or white mineral deposits are forming along an existing crack
How It Works
Our Process for Basement Floor Crack Repair
- 1
Crack Evaluation
We measure width, check for vertical displacement, and look for signs of hydrostatic pressure before deciding on a repair method.
- 2
Preparation
The crack is routed or chased to create clean edges and remove any contaminated or loose material.
- 3
Injection or Fill
Depending on crack width and moisture, we use either polyurethane injection or a semi-rigid filler to seal the crack properly.
- 4
Surface Patch
The filled crack is finished flush with the surrounding floor so it's ready for any flooring installation above.
Ann Arbor Context
Why this matters in Ann Arbor
Ann Arbor sits on clay-rich glacial soils that hold and release water slowly. That soil movement puts consistent stress on basement floor slabs, which is why floor cracks here are so common even in newer construction.
Straight Talk
About pricing & scope
Active water infiltration requires a different approach than a dry, dormant crack. If water pressure is the issue, injection materials and drainage considerations change the scope and the cost.
