What Are Atlas Resistance Piers?

The Atlas Resistance Piles are hydraulically pushed pipe segments used to restore and/or stabilize homes and 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 make them unsafe, thus the need for a cost-effective solution.

Atlas Resistance Piles, also known as push piles or jacked piles, are commonly used to remediate structural settlement. Resistance Piles are hydraulically driven to competent load-bearing strata. The structure as the pile advances in the ground induces a reaction force. Once the pile has been installed to desired capacity, the pile is connected to the footing by the installation of retrofit brackets, concrete haunch on needle beam.

Atlas Resistance Pier Applications

Atlas Resistance® Piers are used primarily for underpinning and the repair of residential and commercial buildings, retaining structures, and slabs. They can be installed in either interior or exterior locations. They have been used to repair equipment and machinery foundations, warehouse buildings, tower foundations, etc. Special remedial repair brackets can be connected to either the bottom or side of an existing foundation. They can also be connected to the sides of circular or flat building columns.

Atlas Resistance® Piers not only stop settlement but can also be used to raise the structure, thus closing cracks and correcting other structural flaws resulting from settlement and/or ground movement.

The design process should involve professional engineering input. Specific information concerning the structure, soil characteristics, and foundation conditions must be evaluated and incorporated into the final design.

Why Choose Atlas for Push Piers?

Atlas Resistance Piers use 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 needs of a project cost effectively.

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

Components of the Atlas Resistance Pier

The Atlas Resistance Pier is a manufactured, two-stage product 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.

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 3 feet square. The pier may be installed from the interior or on the exterior of the footing.
