Foundation Watering and Expansive Soil

What is Foundation Watering and Expansive Soil?

Expansive soil is known to be present in every US state and throughout the world. Every year, expansive soils contribute to billions of dollars in damage to homes. In a typical year, expansive soils cause greater financial loss to property owners than earthquakes, floods, hurricanes, and tornadoes combined. The proper design and care of your foundation is very important to preserving the integrity of your home.

The Causes of Foundation Watering and Expansive Soil

If the soil around the exterior of the home becomes excessively dry, it will shrink, leaving a gap between the soil and the foundation. These cracks allow additional evaporation and more cracking deeper in the soil. When heavy rains happen, these cracks allow excessive amounts of water to penetrate soil layers causing swelling of the clay soils that are intended to support the foundation. This rapid expansion can cause settlement, foundation cracking, drywall cracking, and the need for foundation repairs.

The lack of uniform moisture levels can be caused by:

  • Neglect
  • Lack of guttering and downspouts on the home
  • Improper drainage
  • Plumbing leaks
  • Improper grading
  • Excessive watering
  • Trees too near the foundation
  • Poor soil conditions

Expansive soils, combined with a shallow foundation, create a scenario that can manifest itself into major foundation problems. Shallow foundations (foundations very near the surface) rest upon soils that are greatly influenced by rain and ambient temperatures. These foundations become highly susceptible to the movement which causes cracking and structural damage. Opposed to deep foundations (foundations that are set below the zone of influence), shallow foundations are cheaper and account for the greatest financial losses due to foundation repairs and structural failures.

Foundation Failure Prevention

The most effective solution to foundations in expansive soil areas is through professional design. A deep foundation along with proper guttering, grading and landscaping will create an effective foundation for homes and commercial buildings alike without the concern of structural cracking and foundation repair work.
