How Concrete Leveling Works
The A-1 Concrete Leveling process for leveling concrete, sometimes called mudjacking, allows us to return uneven concrete to its original level position without the cost of pouring new concrete. At its simplest form, we fill any void under your slab with a limestone grout slurry mixture which in turn lifts the concrete in place. It is safe and effective for many applications and in most cases can be completed in a matter of hours instead of days for new concrete.
Our 3-Step Process
- Small holes (1 inch diameter) are drilled through the sunken concrete block at strategic locations.
- A finely crushed, highly dense limestone aggregate (sometimes combined with Portland cement), is combined with water in a “slurry” consistency then pumped into the holes. Once any voids, created by erosion or soil compaction, have been filled, the block will begin to rise. As the slurry begins to flow under the slab, it exerts an even pressure across the entire slab and can easily raise the concrete. Through strategic placement of the drilled holes, and control of the amount of material injected into each, the block will be carefully raised into final position.
- During the last step, the holes are filled with non-shrinking grout leaving the slab looking nearly new.
Common Concrete Leveling/Mudjacking applications include:
A-1 Concrete Leveling can save you up to 70% over the cost of tearing out and replacing your concrete.

Aaron is one of our Louisville concrete leveling experts. He understands intimately how concrete slabs move, and what it takes to get them back in the right place. If he is on your job, you know it’ll be done right.
I contracted with Andrew Gray of Keystone Foundation Repair to come lift our sunken front porch slab, and was told that it would be a relatively easy and routine job to lift the slab about 8 inches. It wound up being a nightmare situation, but not because of anything that the workmen did. In fact, the crews spent two full days valiantly trying to lift the slab using first foam and then composite, but to no avail. (They had easily and successfully lifted a sidewalk of ours without issue, but the porch slab would not budge.) Andrew apologized profusely and said he would not charge us a single dime for the two days of work, including the unrelated sidewalk repair, because he hadn't been able to accomplish what he promised, even though it was due to circumstances beyond his control. Furthermore, he personally came back to our house a number of times after that, at zero expense to us, to make us whole--scrubbing, cleaning, and power washing on his own time. He handled the whole situation extremely professionally and scrupulously, striving to make sure we were completely satisfied. I would definitely recommend Andrew and his company to anyone who needed foundation repair! This company is most certainly trust-worthy and notable!
