What Causes Foundation Settlement In Missouri?

Foundation settlement and movement in Missouri is typically caused by building on expansive clay, improperly compacted fill soils, or improper maintenance around foundations.

Foundation failure may occur due to a variety of causes. Sometimes root expansion can shift a foundation off its footings. Soil composition, moisture levels, and settlement are contributing factors. Fill soil that is washed away or that swells due to plumbing leaks or other sources of excess moisture can cause shifting, instability, and cracking in your foundation. Drought, freezing and extreme temperature changes are also concerns.

Observing soil moisture changes around your foundation is possible, but what about under it? Moisture can move from outside to under your foundation through a property of soils known as suction. Soil suction is similar to placing just a corner of a dry, compressed sponge in contact with a puddle of water. In a short time, the sponge has drawn water throughout itself and grown in volume.

In most cases, water typically is the culprit!

While a water source is present, the sponge will continue to absorb water until it is saturated. If the water source is cut off, then water already in the sponge will distribute itself evenly, but the sponge will not reach saturation.

Water can move horizontally and vertically through the soils under your foundation in a similar manner. As clay-like soils draw water to themselves, they too grow in volume (swell or heave) causing your foundation to move. Drying outside your foundation reverses the process. The moist soils will lose volume (shrink) as soil moisture moves out from under your foundation, causing the foundation to settle. Shrinking and swelling soil motions can lead to damaging your foundation and structure. Uniform changes in soil moisture are less damaging to your structure than localized changes. We know that soils vary from location to location. For example, Jefferson City may have more rock-based soils while Warrenton would hold more clay-based soils.

Judy and I would like to thank Mark and his crew for the excellent work they did restoring our basement.  These young men conducted themselves in a professional manner; were pleasant and polite; and open to our suggestions and ideas.

It was refreshing to see this group of young people work together as an efficient team to complete a complicated task.
