AI-Powered Is Clay Soil Weakening Your Home’s Foundation?
While expansive clay soil is common throughout the U.S, it can be detrimental to a home’s foundation and landscaping. As a homeowner, it’s important to know how to look for signs that you live in an area with expansive clay soil and what you can do to avoid damage.
As foundation repair professionals, Groundworks has the expertise to help you identify signs of expansive clay soil and address the damage to your foundation.
What are Expansive Clay Soils?
Expansive clay soils are types of soils that expand when exposed to significant moisture. Clay minerals in the soil can absorb water and expand, causing the soil to swell. On the other hand, when the soil dries out, it contracts and shrinks.
Soils rich in silt or clay have the greatest swelling potential and therefore the greatest potential for foundation damage. They can cause foundation settlement, heaving, and cracks, which are costly to repair.
On the other hand, when summer rolls around and the heat increases, the soil dries out and contracts. This plays out in a sort of slow, pulsating motion that wears away at your foundation throughout the year in different ways.
Why Does Clay Soil Expand?
Clay soil expands due to the unique characteristics of the minerals in the clay. Clay particles have a high surface area and a negative charge, allowing them to attract and hold water molecules. When water is absorbed, the clay particles swell, and the soil expands.
For example, during heavy rains, clay soil can expand more than 10% in volume. Wet clay soil can weigh more than 100 pounds per cubic foot, creating a damaging force known as hydrostatic pressure that pushes against foundation walls.
