Underpinning Systems

Foundation Underpinning provides additional support to foundations and is used to increase foundation depth or repair faulty foundations that are unable to safely support existing or planned loads.

Underpinning can be performed on existing structures or support foundations in new construction. In both cases, poor quality of the soil beneath the building can cause the structures to shift over time. Underpinning is the quickest and least disruptive solution to keep foundations firm.

Foundation Underpinning Systems

For stabilizing/lifting foundations or retrofitting to increase load capacity, CHANCE® steel piers are installed at intervals around the perimeter at affected locations. Independent of the structure, the piers are extended to depths which attain the installing torque correlated to the required load bearing capacity.

Special brackets are located where needed around the perimeter and secured to the concrete foundation.Then a steel pier is torqued into the soil through each bracket. The brackets permit lifting by hydraulic jacks. Tightening the nuts on the bracket vertical bolts locks off the load.

Advantages to repairing foundations with CHANCE® Underpinning systems:

  • Bypass the problem soils and reach competent soil below active zone
  • Predictable capacities based on torque during installation
  • No excavation or spoils to remove
  • Loads may be immediately applied
  • Installs in limited access/low headroom
  • Installs in any weather condition
  • Minimal to no vibrations or noise
  • Quick installation time
