As a homeowner, discovering a sunken driveway or a shifting sidewalk is a safety hazard and liability. When you begin researching how to “raise and level concrete,” you’ll quickly encounter two competing methods: Polyurethane Foam Injection (Polyfoam) and Traditional Mudjacking.
At Concrete Raising & Leveling, we’ve spent 45 years perfecting our craft across Michigan. We believe in providing solutions that are effective, durable, and, most importantly, safe for your home and family.
What is Polyfoam (And Why We Avoid It)?
Polyfoam involves injecting a two-part chemical mixture (including isocyanates) beneath your concrete. While it is marketed as a “modern” or “lightweight” fix, there are significant concerns regarding its chemical makeup.
Chemical Risks: The primary ingredient, isocyanates, can pose health risks if not handled or cured perfectly.
Environmental Impact: These are non-biodegradable synthetic materials being pumped directly into your soil.
Cost: Polyfoam is often significantly more expensive due to high material costs.
The CRL Difference: Eco-Friendly Limestone Mudjacking
We utilize a refined version of mudjacking that replaces “mud” or “slurry” with crushed and filtered agricultural-grade limestone.
- Safety First (Health & Soil)
Unlike isocyanate-based foams, our limestone mixture is non-toxic and eco-friendly. Because it is a natural mineral, it poses zero risk to your family, your pets, or the local groundwater in Lansing, Ann Arbor, or Jackson.
- Structural Density and Support
Polyfoam is lightweight, which sounds good until you consider the physics of a heavy concrete slab.
Limestone: Provides a dense, solid foundation that mimics the natural earth. It fills the “voids” completely, ensuring your slab has 100% support.
Stability: It is less likely to shift or compress under the weight of a vehicle compared to some foam applications.
- Precision and Control
Our limestone slurry is pumped at a controlled pressure, allowing for a gradual, precise lift. This reduces the risk of over-lifting or cracking the slab, which can sometimes happen with the rapid expansion of chemical foams.
The Bottom Line for Michigan Homeowners
You want a level driveway, but you also want peace of mind. Why put synthetic chemicals under your yard when a natural, stronger alternative exists?
At Concrete Raising & Leveling, we choose limestone because it aligns with our 45-year commitment to honesty, reliability, and quality. We treat your home like it’s our own.
