Behavior and Effects of Expansive Soil, Copyright Prentice HallWith the Onset of Summer, Comes Contracting Soil

After a fall and winter of higher than average rainfall in Central Texas, thanks to El Nino, a dry summer has the potential to wreak havoc on building foundations across the region.

Soil in Central Texas has Expanded
Due to Recent Rainfall

The soil composition here in Central Texas is comprised of moderate to highly expansive soils, see our post on expansive soils. What this means is that in wet periods our soils absorb water and expand, and during dry periods they lose moisture and contract.

Diagram of Expansive Soil, Copyright Prentice Hall In the example at right, taken from a Prentice Hall textbook, we can easily see the amount of moisture present in an expansive soil multiplies when moisture is introduced causing a phenomenon known as soil heave. As the name suggests soil heave causes the soil to lift upward and can either put added pressure on your exterior walls, if the soil under your house remains dry, or on the center of your foundation, if the soil under your home is affected by leaks or other sources of moisture.

Large Cracks in a Foundation or Walls
are Usually a Sign of Foundation Problems

If your home is experiencing any foundation problems, you will most likely either want to have a structural engineer take a look, or call a foundation repair company out to examine your home.

Central Texas sits in an area of the United States which is highly affected by expansive soils. (source: geology.com)

Expansive soils contain minerals such as smectite clays that are capable of absorbing water. When they absorb water they increase in volume. The more water they absorb the more their volume increases. Expansions of ten percent or more are not uncommon. This change in volume can exert enough force on a building or other structure to cause damage.

With the coming wet weather, Central Texas soils will be absorbing moisture, and subsequently expanding which can lead to increased strain on home and building foundations.

In periods of increased rainfall it is important to be cautious when watering your foundation. Ovewatering causes the soil to absorb too much water, thus expanding, and possibly leading to foundation problems. A good tip for watering your lawn/foundation is to water it enough to keep your plants alive and healthy, saturation is neither good for plants nor foundations.

For the time being, however, water restrictions are still in effect, so overwatering should not be an issue until water restrictions are lifted completely.

According to the United States Department of Agriculture Travis County features a smorgasbord of soil types. Some of which are great for supporting foundations and others of which pose plenty of problems for construction.

What type of soil is your home or potential new home sitting on?

This blog article will examine Austin soil types using excerpts from the USDA’s report on Soils in Travis County.

According to the report:

Foundations Shrink-swell characteristics of the soil need to be considered in designing a building foundation, particularly if piers are not used below the slab. Such clay soils as those of the Houston Black, San Saba, and Ferris series are particularly poorly suited to building sites. They swell when wet and shrink when dry. This shrinking and swelling exerts such pressure that walls and foundations crack unless they are specially reinforced, sidewalks and driveways crack, and streets and sidewalks deteriorate more quickly.

In otherwords, beware of the type of soil your house is sitting on.

The report defines shrink-swell potential as follows:

Shrink-swell potential is an indication of the volume change to be expected in the soil material as the moisture content changes. Shrinking and swelling of soils causes much damage to building foundations, roads, and other structures. A high shrink-swell potential indicates hazards to the maintenance of structures constructed in, on, or with such materials.

Essentially the shrink-swell potential of a soil refers to the potential for the soil to shrink or swell based on water retention rates. Or when there is more water in the soil it has a potential to swell, when there is less water in the soil it tends to shrink. This can obviously cause problems for a foundation in that the soil underneath has the potential to change based on the amount of moisture in the soil.

Following is a list of the main soil types that cause problems for residential and commercial builders:

  • Houston Black

    The main limitations in use of the soils of this association in urbanization are the shrink-swell characteristics, as they affect foundations and streets.

    The soils of this unit present problems when used in urbanization. There are special problems in designing and maintaining foundations, trafficways, other works of concrete and asphalt caused by a shrink-swell potential.

  • Lewisville Soils

    There are limitations to the use of this unit in urbanization. Some of the hazards are a shrink-swell potential that affects foundations and pavements.

  • San Saba Soils

    The use of this undifferentiated group for urban development presents problems. These problems are caused by the shrink-swell potential, as it affects design, construction, or maintenance of concrete foundations and asphalt trafficways.

  • Tarrant Soils

    Soil characteristics that affect urban development are shrink-swell potential, as it affects foundations and paving.

  • Urban Land and Austin soils/Urban Land, Austin, and Brackett soils

    Some soil characteristics that affect urban development are shrink-swell potential, as it affects foundations and pavings.

  • Urban Land and Ferris Soils

    The use of this group for urban development is limited. Some of the soil characteristics that affect urban construction are shrink-swell potential, as it affects foundations and pavings.

  • Volente soils and Urban Land

    Some of the soil characteristics that affect urban construction are shrink-swell potential, as it affects foundations and paving.

Know your soil, and your potential for problems, before buying a house or deciding on foundation repair.
