What causes foundation floors cracks?

Are cracks in the foundation floor normal?

Most floor cracks are benign and occur shortly after the concrete floor is poured and shrinks as it cures. These are usually hairline cracks that never change over time.

The two concerns for basement floor cracks are heaving and sinking. Signs of this are uneven cracks where the floor on one side is higher than the other. Another sign could be a crack that is widening.

Heaving occurs when the soil beneath the basement floor is expanding. This tends to occur due to increase in moisture or from freezing. Foundation cracks occur more commonly with slab foundations. A slab foundation represents a concrete floor poured onto the Earth with dug out basement or crawlspace.

Slabs typically have less weight to resist heaving forces. Unless there is a long period of drought, heaves commonly occur within the first few years of the building’s construction. Heaving tends to be more prevalent in areas where there is clay soil.

Sinking can occur when the foundation settles. Sinking or settling happens when the soil beneath dries and shrinks or is washed out. As this happens, gaps form under the concrete floor slab. These gaps create soil voids that can no longer support the floor slab. The floor will then begin to crack and sink into the depression.

Gaps or voids beneath the floor can be caused by groundwater, plumbing leaks or even HVAC systems. If an HVAC system or ductwork is installed beneath the floor slab, air leaks can dry out the soil. Dried soil can shrink and thus create a void.

Similarly, a severe plumbing leak or sustained groundwater can wash soil out from under a slab if there is a path for the water to flow. When this happens, here is nothing to support the slab and it will begin to sink and crack.

Can a cracked foundation floor be fixed?

Yes.

Foundation cracks can be common in a home’s foundation after it is built, and many times the cracks are non-structural settlement cracks and tend to be normal. However, be sure to keep an eye on these cracks if they continue to form or expand. These cracks can be tell-tale signs of an underlying structural issue.

Many small wall cracks measuring under 1/16” are typically a normal shrinkage crack. These can be left as is or repaired quickly and affordably. Even larger cracks can be repaired if there’s no sign of continued movement over time.
