Mudjacking: Raising Settled Concrete Back to Level

Mudjacking is a concrete leveling method that lifts a settled slab back to level by pumping a cement-based slurry through small holes drilled in the surface. The slurry fills the voids beneath the slab and raises it in place. Replacing the concrete means breaking out the existing slab and pouring a new one. For a slab that is structurally sound but has settled, mudjacking is usually less disruptive and more cost-conscious. If a slab is badly cracked or deteriorated, replacement may make more sense, and we will tell you when that is the case.

Mudjacking is commonly used on residential flatwork such as driveways, sidewalks, walkways, patios, porch slabs, and garage floors that have settled and become uneven. Whether it is the right fit depends on the condition of the specific slab and what caused the settlement, which is what we confirm during the no-pressure inspection.

That is one of the main reasons homeowners ask about it. When one section of a walkway or driveway settles below the next, the lip between them becomes a trip hazard. Mudjacking raises the low section back flush with the rest so the surface is even again, which removes the hazard and improves how the concrete looks. We confirm during the inspection that the slab is a candidate for lifting before recommending it.

When the slab is a good candidate and the underlying cause of settlement is addressed, mudjacking can provide a long-lasting lift. The honest answer is that longevity depends heavily on the soil and grading beneath the slab. In active Piedmont clay that keeps swelling and shrinking, or where water is still washing out the subgrade, an unaddressed cause can allow a slab to settle again. That is why we diagnose the cause first rather than just lifting the concrete and leaving.

Cost depends on the size of the slab, how far it has settled, the number of injection points needed, access to the area, the soil conditions, and whether any grading or soil correction is recommended alongside the lift. Because those factors vary from one slab to the next, we provide pricing after a no-pressure inspection rather than a flat number online. The inspection is how we give you an accurate, honest quote for your specific situation.

Not by itself. Mudjacking lifts the slab and fills the void beneath it, but it does not change the deeper soil behavior or grading problems that caused the settlement. If the cause is something like water draining against the slab or unstable subgrade, we address that as part of the recommendation, sometimes with grading corrections and sometimes with a deeper structural solution, so the lift is more likely to hold.
