Concrete spall repair is a crucial service for Ann Arbor homeowners looking to restore and maintain their concrete surfaces.
Spalling occurs when the surface of the concrete begins to flake, chip, or peel away, exposing the aggregate beneath.
If left untreated, spalling can lead to more extensive damage and costly repairs down the line.

Understanding the Signs and Causes of Concrete Spalling in Ann Arbor
Identifying spalling early on is key to preventing further deterioration of your concrete surfaces.
Some common signs of spalling include:
- Flaking or chipping of the concrete surface
- Exposed aggregate or rocks
- Cracks or pits in the concrete
- Rust stains from corroded reinforcement steel
Several factors can contribute to concrete spalling in Ann Arbor, such as:
| Cause | Description | Prevention |
|---|---|---|
| Freeze-thaw cycles | Water seeps into cracks, expands when frozen, and breaks off concrete | Proper drainage, sealants |
| Deicing salts | Salt corrodes concrete and steel reinforcement | Use concrete-safe deicers |
| Poor installation | Improper mixing, curing, or reinforcement placement | Hire experienced contractors |
How Michigan’s Weather Accelerates Surface Deterioration
Michigan’s harsh winters and freeze-thaw cycles can be particularly damaging to concrete surfaces in Ann Arbor.
As water seeps into cracks and freezes, it expands and puts pressure on the surrounding concrete, causing it to chip and flake away.
The frequent use of deicing salts on sidewalks, driveways, and roads also contributes to spalling by corroding the concrete and any steel reinforcement within it.
Over time, this weathering can lead to significant deterioration if not addressed promptly.
Proven Methods to Repair Concrete Spalling for Lasting Results
The best approach to repairing spalled concrete depends on the extent of the damage and the desired outcome.
For minor spalling, a simple patch repair using a polymer-modified mortar can often suffice.
More extensive damage may require a full-depth repair, where the damaged concrete is removed and replaced with fresh material.
In some cases, resurfacing the entire slab with an overlay or coating can provide a more uniform appearance and added protection against future spalling.
| Repair Method | Best For | Pros |
|---|---|---|
| Patch repair | Minor, localized spalling | Quick, affordable, easy DIY |
| Full-depth repair | Extensive, deep spalling | Addresses underlying issues |
| Resurfacing | Widespread, shallow spalling | Refreshes look, adds protection |
The Importance of Proper Surface Preparation Before Repairing Spalled Areas
No matter which repair method you choose, proper surface preparation is essential for achieving a strong, long-lasting bond between the old and new concrete.
This typically involves:
1. Cleaning the area to remove any dirt, debris, or loose concrete
2. Roughening the surface to create a better profile for bonding
3. Applying a bonding agent to help the new material adhere
4. Keeping the area damp to prevent the repair from drying out too quickly
Skipping or rushing through these steps can lead to a weak repair that fails prematurely, so it’s important to take the time to do it right.
