When choosing a method for lifting and leveling sunken concrete, durability matters as much as cost and speed. At Acme Concrete Raising & Repair, we use high-density polyurethane foam because it delivers unmatched long-term performance — proven not just by our results, but by the trust it’s earned from engineering firms, municipalities, and Departments of Transportation (DOTs) across the United States.
Compressive Strength: Built to Withstand Heavy Loads
Polyurethane foam used in concrete raising is engineered with exceptional compressive strength, meaning it can support substantial weight without deformation. Typical polyurethane materials used in our repairs have compressive strengths exceeding 100 pounds per square inch (psi) — more than enough to handle residential driveways, commercial slabs, and even heavy truck traffic on municipal roadways.
This strength ensures that once your concrete is lifted, it stays lifted — resisting future settling under normal use.
Water Resistance: Impervious to Moisture and Erosion
One of the leading causes of concrete settlement is water infiltration and soil erosion. Unlike traditional mudjacking materials, polyurethane foam is completely water-resistant. It won’t absorb water, weaken over time, or wash away during heavy rains or seasonal flooding.
By keeping moisture out of the repair zone, polyurethane helps preserve the stability of your slab and the soil underneath, making it a more reliable long-term solution in areas prone to water-related settlement.
Our 10-Year Warranty: Long-Term Peace of Mind
We stand behind our work with a 10-year warranty on polyurethane concrete raising services. This warranty reflects our confidence in the product and our process — if your repaired slab settles again within the warranty period, we’ll make it right.
Our guarantee is more than a promise; it’s backed by years of proven results and thousands of successful projects.
The Industry Standard: Trusted Nationwide
Polyurethane concrete raising isn’t just our preferred method — it’s the go-to solution for engineers and public agencies nationwide. Departments of Transportation, municipalities, and major construction firms choose polyurethane because of its:
Lightweight strength — won’t overload weak soils.
Fast curing time — often ready for traffic in under an hour.
Long-term stability — proven to perform for decades.
When professionals responsible for bridges, highways, and public safety projects choose polyurethane, it’s a strong signal of its proven durability.
Durability Comparison: Polyurethane vs. Mudjacking
| Feature | Polyurethane Concrete Raising | Mudjacking |
|---|---|---|
| Compressive Strength | 100+ psi, supports heavy loads without deformation | ~30–50 psi, may compress under repeated load |
| Water Resistance | 100% hydrophobic, will not absorb moisture | Absorbs water, can erode or wash out over time |
| Longevity | Decades of performance when installed correctly | May require repeat repairs within 5–10 years |
| Weight Added to Soil | Very lightweight (2–6 lbs per cubic foot), prevents further settlement | Heavy slurry (100+ lbs per cubic foot) can worsen settlement |
| Cure Time | Typically ready for use in 15–60 minutes | Requires 1–2 days for full set before heavy use |
| Industry Adoption | Preferred by DOTs, engineers, municipalities nationwide | Rarely used for high-traffic or critical infrastructure |
Why Durability Should Be Your Top Priority
Concrete raising is an investment — and durability determines your return on that investment. While other methods might cost less upfront, they can require repeat repairs if the materials fail. Polyurethane’s combination of strength, water resistance, and national industry adoption makes it the most reliable choice for homeowners and property managers who want lasting results.
Frequently Asked Questions
How long does polyurethane concrete raising typically last?
When properly installed, polyurethane repairs can last for decades, with many projects performing flawlessly for over 20 years.What is the compressive strength of polyurethane used in concrete raising?
Most high-quality polyurethane foams have compressive strengths over 100 psi, easily supporting vehicle and foot traffic.Can polyurethane foam be affected by water or flooding?
No — polyurethane is hydrophobic and will not absorb water, making it ideal for areas prone to moisture.Does Acme Concrete Raising & Repair offer a warranty on repairs?
Yes, we provide a 10-year warranty, ensuring your slab stays level for years to come.Why do municipalities and DOTs prefer polyurethane over mudjacking?
They value its lightweight nature, fast curing, and long-term durability — critical for high-traffic and safety-sensitive projects.
