FOUNDATION PROBLEMS? YOU MAY NOT NEED FOUNDATION REPAIR…
While causes can be many, most foundation problems result from differential moisture levels in the supporting soils. This allows portions of the foundation to change elevation relative to other portions of the structure. Poor drainage, proximity of trees, leaks, climatic conditions and poor soil moisture maintenance habits are common contributors to this problem. The common denominator regardless of the contributing condition is expansive clay soil. Aside from supporting the building loads, the goal of a structural foundation in expansive soil areas should be to economically mitigate the detrimental effects of inevitable foundation movement.
Slab-on-grade foundations are designed as floating slabs, much the same as a boat floats on water. Foundations do not resist or control soil movement. Rather, they are subject to the effects of soil movement. A properly performing foundation will act as a rigid element that will float on the soil with minimum distress to the structure above.
We only recommend structural foundation repair if remediation with chemical injection, drainage corrections, soaker hoses, root barriers, and or other non structural methods will not return the foundation to acceptable levels. Chemical injection changes the structure of the clay soil and can reduce the shrink/swell capability to less than one inch. This approach can save thousands of dollars for homeowners providing a long-term resolution to foundation problems.
