What Causes Concrete Cracks?

Concrete Slab Settlement Causes

Cracked concrete or a cracked concrete slab is caused by house settlement. Settling is a result of changes in the soil your home is built on and occurs when the ground is no longer able to support the weight of your house.

  • Excess Water
  • Dry Conditions
  • Poor Construction

A lot of rain, inadequate drainage system, or poor grading could be creating problems for the soil your home’s foundation sits on. When wet, the soil expands and becomes soft– like a sponge – and pushes against your foundation, resulting in bowed walls, horizontal cracks, and vertical cracks.

The hot summer days can affect more than your garden, it also evaporates the water from the soil surrounding your foundation. The dry soil pulls away from your foundation, creating a gap, and shifting your home’s foundation. This can cause concrete cracks and vertical cracks in your basement or foundation walls.

The builder may have taken a short cut that has affected the soil your home is built on. After your home’s foundation is poured and dried, soil is dumped outside the foundation to help it stabilize. If the soil wasn’t compacted or the foundation was not completely dry when the soil was pour then concrete cracks can develop.

Concrete Foundations and Slab Settlement

If you’ve tried to repair cracked concrete yourself without being successful, there’s a good chance you’re dealing with a foundation settlement problem. It’s a very common homeowner problem. Note the following settlement signs:

  • Cracks in Concrete Floor
  • Sinking Floors and Wall Separation
  • Interior Wall Cracks – Commonly in Corners

When a concrete floor settles, it can mean serious damage to your home. The causes of floor slab settlement are almost always due to the soils underneath being unable to support the weight of the concrete. Often times settlement accompanies additional foundation problems.

If you find a vertical crack in your foundation or basement that is wider than 1/16″ or wider at the top or bottom, get help from a professional foundation repair contractor immediately. These types of vertical cracks indicate a serious foundation issue.


Can I Fix Concrete Cracks Myself?

Don’t assume that a cracked concrete slab or a concrete crack in your basement can always be repaired with a concrete patch, caulking or sand packing. While these quick-fixes cover up the concrete cracks they don’t address and repair the cause of the cracked concrete: your settling foundation.

It’s best to have your home inspected by a foundation repair contractor before repairing a symptom that may be a sign that you have a serious foundation issue.

Most of the time concrete cracks in your basement floor or walls mean you have a foundation issue. The cracks almost always get worse over time, creating more safety issues and tripping hazards, while becoming more expensive to repair.
