Poor soil and
environmental conditions, inadequate foundation design, and/or improper
foundation construction techniques, can all lead to differential foundation
settlement: which can ultimately lead to varying degrees of damage to any
overlying structures. Key to the proper
design and repair of any foundation which has experienced differential
settlement is to adequately evaluate the cause(s) for the observed settlements. The settlement evaluation process can take
many forms ranging from visual foundation inspection to subsurface exploration
programs aimed at characterizing the foundation subgrade. Once a cause(s) for any differential
foundation settlement has been identified, then a corrective solution can be
engineered to help repair the damaged foundation and help prevent any future
foundation settlements from occurring.
Some common foundation settlement repair methods include:
