A sinking foundation can be caused by a number of different problems. These problems can be permanently corrected using a foundation underpinning system, which stabilizes the foundation and prevents further vertical settlement. Pre-engineered steel piers (galvanized pipes) are installed beneath the base of the foundation wall (footing) and driven into bedrock or load-bearing strata. This is a time-proven method which is more effective and economical as compared to rebuilding the entire foundation on unstable soil. It is also much less invasive.
