Spalling is a surface failure that causes holes in concrete. It is most commonly seen in driveways and foundations and can result from excess moisture, corrosion, improper installation, or weathering. Spalling is unpleasant to look at and can lead to structural issues. Here are the common signs of spalling.

How to Know If You Have Spalling

1. Cracks

Cracks typically occur because of carbonation or when alkalis in the material react with carbon monoxide. If you do not repair these fissures promptly, they will elongate into a bigger, more pressing issue or cause the concrete to fall apart.

2. Flaking

Concrete will flake into pieces if there’s spalling. If the material is coming off in large chunks, water damage is the likely culprit. Large falling pieces of concrete pose a safety hazard to passersby as well as visiting clients or customers.

3. Bubbles

Concrete is intended to be flat and level. If you see bubbles on the surface, have a professional repair it immediately. Bubbles indicate that the concrete wasn’t mixed correctly during installation.

4. Rust

If you see rust on your concrete, the underlying metal support structure likely experienced water damage or oxidation. Rust makes the material look unsightly and deteriorates it. To help your concrete retain its integrity, have a professional regularly inspect the surface and handle repairs as soon as possible.
