Causes of Foundation Failure

Transpiration Tree roots dehydrate the soil beneath a home causing soil shrinkage and differentail settlement of your home.
Plumbing Leaks Water from leaky plumbing is often a major contributor to foundation problems especially in salb on grade concrete.
Drainage Improper drainage or waterproofing can lead to excess moisture build-up, which could erode or consolidate soils. Excessive moisture may cause expansive soils to swell and heave.
Poor Building Site Preparation Cut and fill situations, where soil is removed from part of the lot and stacked on another. This must be compacted properly before your home is constructed otherwise unexpected movements of the soil beneath the foundation may occur.
Poor Ground Preparation Improperly graded home sites often lead to future foundation issues. Grading should always divert water away from your home preventing water to seep under the foundation.
Poor Soil Conditions Poor soil, organic components, debris, etc., may cause consolidation, which contributes to foundation failures.
