Is your basement floor warping?

Find out why it is happening and how to fix it.

What Causes Warped (Curled) Basement Floors?

The two main causes of warping and curling in basement floors is temperature and moisture.

When there is a difference in temperature and moisture between the top and bottom of a concrete slab, sometimes this will cause curling.

Some parts of the concrete slab will be dry and some wet. The dry parts contract and the wet parts do not, leaving parts of the concrete wanting to go up and other parts wanting to sink down.

Oftentimes cracks will occur alongside curling.

A quick note about hardwood floors in basements

If you have a hardwood floor installed in your basement, moisture and temperature can also cause warping in the wood.

Moisture collects under the surface. Some parts will be dry or cool, others will not which leaves parts of the wood warped and other parts not.

What is Warping of the Slab?

Warping of the slab, oftentimes known as curling, is when parts of your concrete slab slant up or downwards because of the temperature and moisture difference in separate parts of the concrete. Dry parts will often curl up along the edges, and wet parts sink down in the middle.

Will Basement Warping Cause Cracks in My Basement Floor?
