Resistance Piers

ATLAS™ Resistance Piers

ATLAS™ Resistance Piers are hydraulically pushed pipe segments used to restore and/or stabilize homes as well as commercial and industrial structures that have settled due to a wide variety of soil problems. Foundation settlement and movement can be caused by building on expansive clay or compressible/improperly compacted fill soils or by improper maintenance around foundations. Whatever the cause, settlement can destroy the value of structures and render them unsafe, thus the need for a cost-effective solution.

Cost-Effective Resistance Piers to Fit Your Job

The ATLAS™ Resistance Push Pier System utilize the weight of the structure as its reaction system to drive or push the pipe pier sections into the soil. Properly installed, ATLAS™ Resistance Piers can prevent settlement, stabilize foundations and nearly restore settled structures to their original positions, often closing structural defects such as cracks and deformities caused by the settlement. Selected by load requirements and soil and structural conditions, ATLAS™ Resistance Piers offer a wide range of capacities that are engineered to best fit the requirements of a project cost effectively.

Composition of a Resistance Pier

The ATLAS™ Resistance Pier is a manufactured, two-stage pile foundation system designed specifically to produce structural support strength. First, the pier pipe is driven to a firm bearing stratum; then the lift equipment is typically combined with a manifold system to lift the structure (if required). This procedure provides measured support strength. Atlas piers are spaced at adequate centers where each pier is driven to a suitable stratum and then tested to a force greater than required to lift the structure. This procedure effectively load tests each pier prior to lift and provides a measured Factor of Safety (FS) on each pier at lift. Workspace is not normally a problem when using ATLAS™ Resistance Piers. They can be installed using portable equipment in an area that measures approximately three feet square. The pier may be installed from the interior or on the exterior of the footing.

Advantages of ATLAS™ Resistance Pier System:

  • Portable equipment allows for installation in areas of limited access
  • Immediate loading
  • Piers are individually load-tested during installation
  • No spoils to remove
  • No vibrations
