Foundation Settlement Assessment and Repair

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:

  • Driven pin-pile foundation supports
  • Helical piers
  • Pressure grouting
  • Drilled concrete shafts/piers
  • Flowable fill
  • Passive/active refrigeration systems (for permafrost soils)
