Causes of Foundation Failure

Evaporation:  

Hot and dry conditions may cause soil to pull away from the foundation. Settlement due to this foundation moisture imbalance could cause cracks to appear throughout the structure. 

Transpiration: 

Tree roots could dehydrate the soil beneath a home causing soil shrinkage and settlement of the home. 

  Plumbing Leaks: 

Water from leaky plumbing is often a major contributor to foundation problems.  

Poor Soil Conditions: 

Poor soil, organic components, debris, etc., may cause expansion or consolidation, which contribute to foundation failures. 

Drainage: 

Improper drainage will lead to excess moisture build up, which could erode or consolidate soils. Excessive moisture may cause upheaval or settlement.  

Poor Building Site Preparation: 

Cut and fill situations, where soil is removed from part of the lot and stacked on another, must have proper soil stabilization before the structure is constructed; otherwise unexpected movement of the soil beneath the foundation may occur.
