Concrete Driveway Surface Issues and Their Causes

There are several ways your driveway can be effected by harmful factors such as harmful deicers and exposure to UV rays.


Spalling occurs when moisture enters concrete and causes the surface to peel or flake away.  This is due to a severe increase in moisture typically caused by a rainy spring or long winter.

Mortar Flaking

Mortar flaking is when small sections of a concrete surface begin to dislodge above aggregate particles. Typically, these pieces are quite small and resemble flakes that occur around particles that have already begun to break down.


When fresh concrete is compacted, the cement and aggregate settle and bond. This causes excess water and air to be displaced, and the lighter materials rise to the surface. If the crew sealing the concrete closes the surface before this process occurs, the air and water become trapped under the surface. This creates weakened sections that eventually detach over time.
