Steel Push Piers vs.
Helical Piers

Our Verdict

For most existing homes with settling foundations, steel push piers are the preferred and more cost-effective solution. They use the home's own weight to drive to bedrock, providing a rock-solid permanent fix. Helical piers are the better choice for lighter structures (porches, additions, garages), new construction, and situations where the structure weight is insufficient for push piers. In expansive clay soils, helical piers can also outperform push piers because the helical plates anchor below the soil's active movement zone. Consult a structural engineer — the right pier type depends on your soil conditions, structure weight, and the nature of the settlement.

Steel Push Piers: Pros & Cons

Driven to bedrock or competent load-bearing strata for maximum stability

Uses the weight of the structure as resistance during installation — ideal for heavy buildings

Can actively lift and level a settled foundation back toward its original position

Minimal excavation — installed from small pits along the foundation footing

Permanent, engineered solution that does not depend on soil conditions near the surface

Most systems are galvanized or epoxy-coated for corrosion resistance

Requires sufficient structure weight to drive the piers — not suitable for lightweight structures

Cannot be installed on new construction (the building must be in place)

Depth requirements increase cost if bedrock is very deep (40+ feet)

Limited to vertical loading — less effective for structures on slopes with lateral soil pressure

Interior pier installation requires access through the slab or crawl space

Helical Piers: Pros & Cons

Can be installed on new construction and existing buildings alike

Does not rely on structure weight — torque-driven into the ground by hydraulic equipment

Load capacity is verified in real-time through torque readings during installation

Effective for lighter structures where push piers cannot develop enough resistance

Excellent for expansive clay soils — helical plates anchor below the active zone

Can be installed at angles to resist lateral (horizontal) soil pressure

Typically 20-30% more expensive per pier than steel push piers

Helical plates can encounter difficulty in rocky or cobble-heavy soils

Not ideal for extremely heavy commercial structures with very high point loads

Torque correlation to load capacity is less precise in some soil types

Slightly more invasive installation — requires larger equipment access

Frequently Asked Questions

How many piers does a typical home need?

Most residential foundation repairs require 6 to 12 piers, though the number depends on the extent of settlement and the foundation's weight distribution. Piers are typically spaced 5 to 8 feet apart along the affected foundation wall. A structural engineer's report will specify the exact number and placement.

Can piers actually lift my foundation back to level?

Yes, both push piers and helical piers can lift a settled foundation back toward its original position. This process is called underpinning and lifting. However, complete restoration to the original elevation is not always possible or advisable if the structure has adapted to the settlement over many years. Your contractor will discuss realistic lift expectations.

How deep do foundation piers go?

Push piers are driven until they reach load-bearing soil or bedrock, typically 15 to 30 feet deep, though they can go deeper in areas with poor near-surface soils. Helical piers are screwed to a depth where torque readings confirm adequate load capacity, usually 10 to 25 feet. Depth varies significantly by region and local geology.

Will pier installation damage my landscaping or interior?

Pier installation requires small excavation pits (about 2x3 feet) along the foundation exterior, which causes minor landscaping disruption that is restored after installation. Interior piers installed through a slab require small access holes that are patched with concrete. Overall disruption is minimal compared to other foundation repair methods — most homeowners remain in the home during the work.
