A fast, affordable solution to lift and level sunken sidewalks, driveways, patios, and concrete slabs without demolition.
What Is Mudjacking?
Mudjacking (also called slabjacking or pressure grouting) is a concrete repair technique used to lift sunken or uneven concrete slabs by pumping a specialized grout mixture beneath them. The process fills voids under the slab, restores its original height, and provides lasting support.
Where Is It Used?
- Driveways and sidewalks
- Garage floors and patios
- Concrete steps and porches
- Warehouse and interior floor slabs
Why Concrete Slabs Sink
Over time, soil erosion, compaction, or moisture changes beneath a slab can create empty pockets. The unsupported slab begins to sink or crack. Mudjacking reverses this by restoring solid support under the slab using high-pressure grout.
Benefits of Mudjacking
- Cost-Effective: Typically 30–50% cheaper than full slab replacement
- Quick Process: Most jobs completed in a few hours
- No Major Demolition: Avoids tearing out and re-pouring concrete
- Environmentally Friendly: Uses natural materials like sand, soil, and cement
- Long-Lasting: Properly applied, results can last many years
How It Works
- Small holes (1–2 inches wide) are drilled into the sunken slab
- A grout mixture (mud slurry) is pumped under the slab through the holes
- The slab is gradually lifted to its original level
- The holes are patched with concrete for a clean finish
Mudjacking vs. Polyurethane Foam Injection
While polyurethane foam injection (Polyjacking) is a newer alternative, mudjacking remains a reliable choice for heavier slabs and outdoor applications. Foam may offer faster cure times, but mudjacking uses natural materials and is often more affordable.
Is Mudjacking Right for You?
Mudjacking is ideal for stable structures with sunken concrete slabs that are still in good condition. However, if the concrete is severely cracked or deteriorated, full replacement may be recommended. Our team at PiersPro will evaluate your slab and soil conditions to recommend the best solution.
