Concrete Slab Repair in Ann Arbor, MI
Slab repair covers the range of surface and structural problems that develop in concrete over time — cracks, spalling, scaling, joint failure, and edge deterioration. The goal is to stop the damage from progressing and restore a surface that is safe and functional. Repair is not the same as replacement, and knowing which one applies depends on what is actually happening beneath the surface, not just what it looks like on top.

When to Call
When You Need Concrete Slab Repair
- Cracks in your driveway are wide enough to catch a finger and still growing
- The garage floor surface is flaking off in layers after years of salt and freeze cycles
- Control joints in a warehouse or shop floor have crumbled and the edges are breaking off
- A patio slab has a hairline crack that water is getting into and widening each winter
- Exposed aggregate on an older decorative slab is pitting and pulling loose
- A loading dock or utility pad has corner or edge breaks from vehicle impact
How It Works
Our Process for Concrete Slab Repair
- 1
Inspect and diagnose
We look at every crack, chip, and scaled area — not just the ones you called about. We check whether cracks are moving, whether the slab is still structurally sound, and whether repair makes sense over replacement.
- 2
Prepare the damaged area
Loose material, spalled concrete, and contamination get removed before anything is applied. Repair material bonds poorly to deteriorated concrete, so prep work drives the quality of the result.
- 3
Cut and profile cracks if needed
Structural or moving cracks are often saw-cut into a defined shape before filling. This gives the repair material a better mechanical hold than filling an irregular crack edge.
- 4
Apply repair material
We match material to the situation — polymer-modified mortar for structural repairs, epoxy or polyurea for cracks, or resurfacer for large spalled areas. No single product works for everything.
- 5
Finish and texture
Repairs are finished to match the surrounding surface texture as closely as practical. Color will not match exactly, especially on aged concrete, and we are upfront about that.
- 6
Final walk and documentation
We walk you through what was repaired, what was left alone and why, and what to watch for. You should understand what you got and what its limits are.
What's included
- Full surface inspection of the slab before any repair work begins
- Mechanical preparation of all repair areas — grinding, chipping, or saw-cutting as needed
- Application of appropriate repair materials matched to the type and severity of damage
- Texturing of repaired areas to blend with surrounding surface as closely as possible
- Cleanup of all debris, dust, and material waste from the work area
- Walk-through explanation of what was done and what the repair is expected to handle
What's not included
- Slab lifting or releveling — surface repair does not fix a sunken or tilted slab
- Sealing or coating the full slab surface unless specifically scoped and agreed on
- Repairs to actively moving cracks caused by ongoing settlement or structural failure
Real Situations
Common Scenarios in Ann Arbor
A homeowner near Kerrytown has a 1950s-era concrete driveway with multiple intersecting cracks and surface scaling from decades of road salt tracking.
We assess which cracks are dormant and which are still moving. Dormant cracks get routed and filled. Active ones get evaluated for whether the slab is still worth repairing or if replacement is the honest answer. Scaling gets ground back and resurfaced where the base concrete is still sound.
A business on the south side of Ann Arbor has a concrete loading pad with two broken corners from years of delivery truck contact.
Corner repairs need to be formed and poured properly to handle load — we do not just trowel mortar onto a broken edge and call it done. We form the corner, place appropriate repair concrete, and cure it before it goes back into service. It will be visible as a repair, but it will hold.
A University of Michigan area landlord has a rental property with a basement floor that has a wide crack running across most of the room, and the tenants are concerned about it.
We check whether the crack is structural or just a typical shrinkage crack that has widened over time. Most basement floor cracks in this area are the latter. We clean it out, fill it with the right material, and explain what it is. If something more serious is going on, we say so plainly.
Ann Arbor Context
Why this matters in Ann Arbor
Ann Arbor averages around 60 freeze-thaw cycles per year, which is punishing on concrete that was placed without adequate air entrainment or cured poorly. A lot of the flatwork from the postwar building boom in neighborhoods like Cobblestone Farm area and Lansdowne is now past its design life and showing it. Surface repair extends the functional life of slabs that still have structure left, which is often the more practical choice given the disruption and cost of full replacement.
Straight Talk
About pricing & scope
Repair scope depends heavily on what we find when we start prepping — sometimes damage runs deeper than the surface shows. If we open a crack and find it goes all the way through, or if the concrete underneath is too deteriorated to bond to, that changes what we can offer. We stop and talk to you before expanding the scope without your agreement.
