When comparing foundation repair methods, the choice between polyurethane foam and steel piers depends on whether you need surface-level leveling or deep structural support. As The Experts in Steel Piers, we have specialized in these solutions since 1996 to address the unique challenges of Colorado’s expansive clay soils.

Polyurethane Foam Injection

Polyurethane foam is primarily used for Polyurethane Foam Lifting (slab jacking) to level concrete slabs, sidewalks, and driveways.

• Pros: It is a fast, minimally invasive process where the foam expands and hardens within minutes. It has a lower upfront cost and requires fewer labor hours.
• Cons: It is limited to shallow depths (2–4 feet) and provides lower load capacity (20–30 kips). It can degrade over time and may require reapplication if the soil shifts, as it does not reach deep load-bearing strata.

Steel Helical Piers

For serious structural settlement, diagonal cracks, or bowing walls, Helical Piers are the preferred solution for foundation underpinning.

• Pros: They provide superior performance in installation of helix pier systems by anchoring deep into stable soil or bedrock (up to 60+ feet). They offer immediate loading with no cure time, predictable engineered capacities (up to 200+ kips), and are hot-dip galvanized for long-term corrosion resistance.
• Cons: The initial investment is higher due to the use of galvanized steel and hydraulic installation equipment. However, they provide lasting structural stability that foam cannot match.

Choosing the right method requires a professional on-site evaluation. We recommend consulting a licensed structural engineer for definitive design recommendations.
