Which is Better for Fixing Uneven Concrete Slabs: Foam or Piers?

Choosing between polyurethane foam and steel piers depends on whether you are addressing a cosmetic surface issue or a structural foundation problem. We offer both solutions and can help you determine the best fit for your specific site conditions in Colorado.

Polyurethane Foam Injection

Polyurethane foam is primarily used for Polyurethane Foam Lifting (also known as slab jacking). This method is best for:

  • Surface-level leveling: Ideal for lifting and leveling settled concrete slabs, sidewalks, driveways, and patios.
  • Void filling: Effectively fills empty spaces beneath concrete and compacts surface soils.
  • Speed: The foam expands and hardens within minutes, though it is generally limited to shallow applications (typically 2–4 feet deep).

Steel Helical Piers

We are The Experts in Steel Piers, which provide true foundation underpinning. Steel piers are the superior choice for:

  • Structural support: Engineered to stabilize heavy-load applications, such as diagonal cracks in walls or major foundation settlement.
  • Deep stabilization: Our Helical Piers are driven 10–50+ feet deep to reach bedrock or stable load-bearing strata, bypassing the expansive clay soils common in Littleton.
  • Immediate results: Steel piers offer immediate loading with no cure time, and provide a significantly higher load-bearing capacity (up to 200+ kips per pier) compared to foam.
  • Longevity: Designed to last for decades, our piers utilize hot-dip galvanization for robust corrosion resistance.

As a family-owned and operated company since 1996, we recommend a professional on-site inspection to provide a custom-quote solution. While foam is a fast, cost-effective option for non-structural leveling, steel piers deliver the permanent stability required for structural restoration.
