Before we can advise you on the best foundation repair method to fix your problem, we need to understand the nature of you problem.
In North Texas foundation problems typically arise from either settlement or heave.
Heave is caused by the expansion of clay soil. Expansion occurs when the moisture level increases in clay. Heave may be induced by poor drainage or plumbing problems.
Settlement problems may arise from improper soil compaction, slope failure, or soil erosion.
Soil erosion is caused by either a plumbing leak or bad drainage. Soil erosion problems are relatively rare.
Slope failure is common in hilly regions or near streams or in coastal areas. Slope failure is relatively uncommon in much of the Dallas Ft Worth Metroplex. There are some problematic hilly areas and houses near streams which require careful evaluation.
Often, soil settlement arises from soil consolidation. Consolidation problems arise when the property developer fails to adequately compact the clay during site preparation. Clay is exceptionally hard to compact.
The Foundation Repair Association has developed a program to train inspectors to look to the root cause of the foundation problem, be it heave or settlement, before making a specific repair recommendation.
