What is Mudjacking?

Mudjacking (or mud jacking) is a more generic term, often applied to any grout-based leveling method. In fact, mudjacking is a specific term for a type of leveling usually associated with injecting a soil-based grout under slabs to perform the concrete repair.

So, when asking the question, what is mudjacking concrete? You must first know whether you are thinking of it as a generic concrete leveling term, or the specific process called mudjacking. While A-1 doesn't use this specific method, our process is sometimes lumped in with mudjacking, so we'll talk about both here.

A-1 Concrete provides a superior service to typical residential and commercial mudjacking services. A-1's process uses a stone slurry grout material pumped through 1" holes, while mudjacking uses larger holes, sometimes up to three inches in diameter.

Both processes are used to level concrete slabs around homes and businesses, but A-1 has several benefits over typical mudjacking contractors.

Mudjacking Cost

Whether it is for aesthetic or safety reasons, both stone slurry grout leveling and mudjacking are a very cost-effective and efficient way to raise sunken sidewalks, driveways, patios, and basement floors.

Having level sidewalks, steps, or driveways can mean peace of mind as kids are playing, the elderly come and go, and when removing ice or snow. Both methods are a proven, practical, and inexpensive alternative to concrete replacement.

Cost for both mudjacking and stone slurry grout leveling can be similar, but due to the fact that contractors can usually complete a job more quickly with the A-1 method of concrete leveling, our services will usually come out a bit lower in price. This is especially true for larger jobs, or where a large void is present under the slab.

But, price isn't the only factor in determining what method to use. Take a look at the more significant differences below.

Differences between Mudjacking and A-1's Stone Slurry Grout Leveling

Hole Size

The biggest difference between mudjacking and stone slurry Ggrout leveling is hole size. Mudjacking typically uses holes between 2" and 3" in diameter. Stone slurry grout leveling uses holes that are 1" in diameter, or about the size of a quarter.


Another difference is that typically mudjacking uses a mobile cart, that is filled from a hopper on a truck, then wheeled over to the slab that needs to be lifted. Our crews pump directly from the truck, through hoses at least 200 feet in length. This can make the process much quicker.

Material Durability 

Finally, mudjacking contractors use a soil-based product to pump under the slab, whereas A-1's process uses pulverized limestone. Unless mudjackers put other additives in their mixture, like portland cement, when complete their foundation is simply soil.

Limestone, even without cement added, will dry out and solidify in a near-concrete state. This creates a solid base that is much stronger and less likely to wash out or cause more settling.

How Long Does Mudjacking Last?

Both mudjacking and stone slurry grout leveling can last for the life of the concrete above it, provided the original cause of the sinking concrete has been addressed.

Stone slurry grout leveling does have a bit of an advantage over traditional mudjacking simply because of the nature of the material, and the tendency for the pulverized limestone to harden to near concrete-like consistency.

Once hardened, it would be very unlikely to wash out from beneath the slab, whereas the soil-based material from mudjacking doesn't have that advantage.

What a professional group of men who showed up and I and others did not know how to move cement steps that moved. I was totally impressed and would recommend Jeff Aaron and Joel Thanks so much.
