ATLAS Resistance® Push Piers
What is a Push Pier?
Push Piers are hydraulically pushed steel pipe pier segments used to restore and/or stabilize home foundations 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.
Benefits of ATLAS Resistance® Push Piers by CHANCE™
The ATLAS Resistance® push pile system utilizes the weight of the structure as its reaction system to drive or push the pipe pier sections into the soil. Properly installed, a resistance pier system foundation can prevent settlement, stabilize 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 Resistance Piers
The CHANCE™ ATLAS Resistance® pier foundation system is a manufactured, two-stage push 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 Resistance® piers are spaced at adequate centers where each push pile 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 push pier may be installed from the interior or on the exterior of the footing.
Advantages of the ATLAS Resistance® push pile foundation system:
- Portable equipment allows for installation in areas of limited access
- Immediate loading
- Push piers are individually load-tested during installation
- No spoils to remove
- Hydraulic push pier system generates no vibrations
