Pasadena’s geography is flat and the soils contain a high percentage of clay. Clay soils are the some of the worst soils upon which to build rigid concrete slab foundations. Why? Because clay soils “move” in that they expand and contract with changes in water content. When the area experiences hot, dry weather the clay soils will lose moisture and shrink. When the area experiences wet weather, the clay soils will absorb large volumes of water and swell. That creates “uplift” forces that can push portions of a concrete foundation upward and crack the foundation  Don’t wait, contact us for a Free Foundation Repair Evaluation.
