Polyurethane foam concrete raising is a cutting-edge, efficient solution for lifting and stabilizing sunken or uneven concrete surfaces in Crystal Lake, IL. Acme Concrete Raising & Repair uses an advanced patented process called the Smart Lift System®, which utilizes high-density expanding polyurethane foam to restore concrete slabs safely and quickly.
Step-by-Step Process of Polyurethane Foam Concrete Raising
1. Inspection and Assessment
Before lifting begins, experts perform a comprehensive inspection to assess the condition of the concrete and the underlying soil. This helps determine the best lifting strategy and injection points.
2. Drilling Small Injection Holes
Technicians drill clean, precise holes about the size of a dime (approximately 3/8 inch) into the affected concrete slab at strategic spots. These minimally invasive holes provide access for foam injection.
3. Installing Injection Ports
Specialized injection ports are inserted into the drilled holes, allowing for controlled and clean foam delivery beneath the concrete slab.
4. Injecting Polyurethane Foam
Using proprietary polyurethane injection equipment, a two-part liquid polymer is injected through the ports. The liquid undergoes a chemical reaction, rapidly expanding into a dense foam beneath the slab.
5. Lifting and Stabilizing the Concrete
As the foam expands, it fills voids in the soil and exerts upward pressure to gently lift and level the concrete slab to its original height. The process is carefully monitored and adjusted in real time to ensure even lifting and avoid over-raising.
6. Curing and Sealing
The polyurethane foam cures and hardens quickly—usually within 15 minutes—allowing the concrete to support weight immediately. Injection ports are then removed, and the small holes are patched with high-quality grout, leaving the surface virtually unchanged.
Why Polyurethane Foam Is the Preferred Method in Crystal Lake
Lightweight but Strong: The foam’s compressive strength exceeds many traditional lifting materials, suitable even for heavy traffic areas.
Fast Cure Time: Immediate usability reduces downtime for homeowners and businesses.
Environmental Resilience: The foam is water-resistant, won’t wash out, shrink, or expand with moisture changes—ideal for Crystal Lake’s weather conditions.
Minimal Disruption: The process involves small holes and no heavy equipment, protecting landscaping and structures.
Long-Lasting Stability: Polyurethane foam lifts and stabilizes concrete for decades, backed by Acme’s industry-leading warranties.
Aftercare Tips for Long-Term Concrete Health
- Regularly inspect lifted concrete for signs of erosion or settling.
- Maintain proper drainage to prevent water accumulation under slabs.
- Seal concrete surfaces periodically to preserve integrity.
- Avoid heavy equipment or loads beyond the slab’s rated capacity.
Frequently Asked Questions About Polyurethane Foam Concrete Raising
How long does the polyurethane concrete raising process take?
- Most concrete raising projects are completed within a day. The polyurethane foam cures in about 15 minutes, allowing the surface to be used immediately after.
Is the polyurethane foam safe for my family and the environment?
- Once cured, the foam is inert, non-toxic, and environmentally friendly. It does not leach chemicals and is safe for residential use.
Will my concrete stay level permanently after foam lifting?
- Yes, the high-density foam stabilizes the soil and prevents future shifting, providing a lasting repair often backed by a 10-year warranty from Acme.
Can polyurethane foam lifting be used on all types of concrete surfaces?
- Yes, it is effective for patios, sidewalks, driveways, pool decks, garage floors, steps, and more.
How do I know if my sunken concrete needs raising or replacement?
- Acme Concrete provides free evaluations to determine if lifting with foam is suitable or if replacement is necessary due to extensive damage.
