“Professional OEM Supplier                  For Helical Pile System”

When structures experience settlement, unstable soil, or uneven load distribution, deep foundation solutions such as steel push piers and helical anchors (screw piles) offer dependable remediation and support. Better Screw Co. is spotlighting how these two foundation methods — each with unique advantages — are used in modern construction and repair projects, helping engineers and contractors choose the right system for specific structural demands.

Steel Push Piers vs Helical Anchors — A Comparative Look

Steel push piers are driven vertically into load-bearing strata beneath footings using hydraulic pressure. They are particularly effective for lifting settled foundations, transferring loads to competent soil or rock layers, and stabilizing structural elements affected by settlement. Push piers are widely specified in residential and light commercial foundation repair.

Helical anchors (screw piles), on the other hand, are twisted into the ground, transferring both compression and tension loads through helically shaped plates welded on the shaft. Because of their installation method, helical anchors offer immediate load-bearing capacity and can be used where uplift, lateral movement, and compression loads are anticipated — such as in marine structures, retaining walls, or pedestrian bridges.

When Helical Anchors Shine

Helical systems are often chosen when:

• Soil conditions are variable, soft, or difficult to penetrate with driven piers

• Immediate load application is needed — without waiting for cure times

• Lateral and uplift resistance are critical (e.g., wind-loaded structures)

• Minimal soil disturbance is desired due to landscaping or utilities

• Commercial developers and highway engineers are increasingly deploying helical anchors to support signage foundations, light poles, and equipment pads where dynamic loads and soil inconsistency present challenges.

Hybrid Approaches — Best of Both Worlds

In complex foundation repair cases, combining steel push piers and helical anchors can be advantageous. For example:

• Push piers carry the dead load and resist settlement

• Helical anchors provide uplift resistance and lateral stability

This hybrid approach is especially useful in seismic zones or where soil layering varies significantly within short depth distances.

Real-World Applications

Contractors in the U.S., Canada, and Australia have applied these systems successfully in scenarios like:

• Stabilizing homes with uneven settlement

• Underpinning commercial slab-on-grade foundations

• Securing outdoor equipment platforms and oversized signs

• Supporting retaining walls and basement walls requiring tension resistance

Engineering Confidence and Installation Efficiency

What unites push piers and helical anchors is a focus on predictable performance and efficient installation. Helical anchors are installed with compact equipment that reduces site disruption — a clear advantage on tight residential lots or urban commercial builds. Push piers, with their vertical drive, deliver exceptional load transfer where deep competent soils exist.
