FAQ
What is concrete lifting?
Concrete lifting is a repair process that raises and levels sunken concrete slabs by stabilizing the soil beneath them. At Olympic Concrete Lifting, we use polyjacking—a modern method that injects high-density polyurethane foam under the slab to fill voids and restore proper support.
How long does the process take?
Most concrete lifting projects are completed in a few hours. In many cases, the repaired area is ready for use the same day.
Will the foam wash out or break down over time?
No. The polyurethane foam we use is waterproof, non-toxic, and resistant to erosion, moisture, and pests. It will not wash out like traditional mudjacking materials.
Can you lift cracked concrete?
Yes, as long as the slab is structurally sound. Minor to moderate cracking is common and does not usually prevent lifting. If replacement is the better option, we’ll tell you upfront.
What types of concrete can you lift?
We lift driveways, sidewalks, patios, garage floors, pool decks, basement floors, shed pads, and more. Residential and commercial projects are both welcome.
How much does concrete lifting cost?
Concrete lifting typically costs significantly less than full concrete replacement. Pricing depends on slab size, degree of settlement, and site conditions. We provide free, no-obligation evaluations.
How is polyjacking different from mudjacking?
Mudjacking uses a heavy cement-based slurry that can add weight to already unstable soil and may wash out over time. Polyjacking uses lightweight, waterproof foam that expands with precision, cures quickly, and is designed for long-term stability.
Is polyjacking a permanent solution?
Polyjacking is designed to be a long-lasting repair. By filling voids and stabilizing the soil beneath the concrete, it helps prevent future settlement. Like any concrete repair, long-term performance also depends on proper drainage and soil conditions.
How big are the holes drilled in the concrete?
Polyjacking requires small, discreet injection holes—typically much smaller than those used for mudjacking. These holes are patched after the lift is complete.
Is polyjacking safe for my home and landscaping?
Yes. Polyjacking is a non-invasive process that does not require heavy equipment or excavation. Surrounding landscaping, structures, and foundations are left undisturbed.
Do you offer a warranty?
Yes. Olympic Concrete Lifting stands behind its work with a dependable warranty. Specific coverage details will be explained during your estimate.
How do I know if my concrete can be lifted?
If the slab is intact and not severely broken, lifting is often possible. The best way to know is with a professional evaluation—we’ll assess the concrete, soil conditions, and recommend the right solution.
