Why would someone need foundation piers? Several reasons are outlined below.
1. Evaporation: Hot dry wind and intense heat will often cause the soil to shrink beneath the foundation. This settlement may cause cracks to appear throughout the structure.
2. Transpiration: Tree roots may desiccate the soil beneath a home causing the soil to shrink and the home to settle.
3. Plumbing Leaks: Water from plumbing leaks is often a cause of foundation problems.
4. Drainage: Improper drainage is one of the leading causes of foundation failure. Excess moisture will erode or consolidate soils and cause settlement.
5. Inferior Foundation Construction: Insufficient steel and inferior concrete will contribute to movement in the slab.
6. Inferior Ground Preparation: Soft, low density soils and/or improperly compacted soil beneath a home is the leading cause of foundation failure. Cut and fill methods area leading cause of foundation settlement.
7. Poor Soil Conditions: Poor soil and its expansion and/or contraction contribute to foundation failure.
