Pier & Beam Repair
Pier and beam foundations present unique foundation problems. Due to the many variables associated with pier and beam foundations, only a trained specialist or foundation repair service should propose a plan of repair. All Geo-Tech evaluators are trained in both slab foundation and pier & beam foundations.
Common Causes of Foundation Problems
In one word; water, either there is too much or not enough. Homes in Texas are particularly prone to foundation problems primarily due to the highly expansive clay soils common to the region. Soils with a high clay content respond to moisture like a sponge, they expand with moisture gains, and contract with moisture loss.
If all the soil beneath a foundation swells and contracts uniformly, there usually is no problem. Problems occur when only part of the foundation settles. Then, the difference in movement can cause cracks and other damage. The problem shows up in both slab and pier and beam type foundations. In residential and commercial properties, foundation settlement problems can result in potential damage to the structure, equipment malfunctions, potential accidents, and loss of property value. Consistent moisture is the key.
When there is too much moisture in the soil:
When water is allowed to pool near or against the foundation, 1 of 2 things will occur. The first is that the soil will absorb the moisture causing the soil to expand and this will heave (lift) the foundation causing foundation damage. Conversely, when the soil is saturated, it can lose its ability to carry a load. This will cause the foundation to sink into the saturated area, like quicksand. Water, both standing and running, can also dissolve and carry soil which supports the foundation. Wet spots can be caused by negative drainage, dripping faucets, leaking drains, plumbing leaks, air conditioning condensate drains, etc. The effect is much more pronounced if the surrounding soil is dry.
When there is not enough moisture in the soil:
Generally speaking, soil that is under the interior of the foundation stays fairly consistent throughout the year. The soil near the perimeter of the foundation however, is exposed to the sun, wind other agents that can remove moisture from the soil.
The extreme Texas heat can exacerbate moisture loss around the perimeter of the foundation, especially on the west and south sides of the structure since these sides are exposed to more sun than the east and north sides of the house. This can result in differential movement of the foundation.
Trees and other large plants can significantly contribute to unequal settlement of a foundation. The roots of trees and large plants consume the moisture from the soil, causing the soil to shrink much faster than other areas. A large tree can consume up to 75 gallons of water per day! This loss in moisture can cause the areas closer to the trees and foliage to shrink more rapidly and sink lower than other areas of the foundation.
Poor compaction of native soil during construction:
Slab on grade foundations depend on the uppermost soil layers to provide support for the structure and keep the foundation stable. If during construction, fill dirt is not properly compacted during grading, the foundation will settle as the supporting soil compacts and consolidates.
