Mudjacking uses a grout-based material, fused with cement. The process requires a 1" diameter hole, which is drilled through the slab, which the grout is then hydraulically pumped under the slab, resulting in the voids filling in, causing the slab to be lifted. The material for this process weighs approximately 100 lbs per cubic foot

   Mudjacking Involves:

  • Drilling a series of 1" diameter holes

  • Hydraulically pumping a grout-based material underneath the slab

  • May require more holes than polyjacking would require, to properly fill in voids. The injected grout takes approximately 24 hours to cure

  • Drilled holes are sealed with a non-shrink grout

  • Material weighs approximately 100 lbs per cu. ft.

Whether its mudjacking, or polyurethane foam injection (polyjacking), both are designed to accomplish the same results, which is to fill in voids and raise sunken concrete. 


Slabjacking is very common in the residential market. We have become the experts in raising sunken concrete, by offering both mudjacking and polyjacking (polyurethane foam injection). We take pride in our services, and always do the job the right way. Mudjacking requires drilling a 1" hole through the surface of the concrete, then pumping a slurry underneath the slab, which results in lifting and leveling the concrete. Why choose mudjacking? Mudjacking is a great solution to raising concrete. The material is cost effective, properly fills in the voided area underneath the concrete, raising it to its proper height. The overall cost to do mudjacking is much less than remove and replacing, and generally less than our polyjacking service.

Mudjacking vs/  Polyjacking

Polyjacking: The polyurethane foam, once injected into the soil, quickly integrates with the soil, and expands into a lightweight, stable, durable material, which will increase the soil load bearing capacities.


Mudjacking: The slurry used for mudjacking, once pumped underneath the slab, will fill in the voids, resulting in raising the concrete to its corrected height.


The polyurethane has an impressive lifespan, for it is not affected by water, does not change its shape or form, and will not break down over time as other materials often do. This technology is now the preferred concrete repair solution for municipalities, DOT's, contractors, and residential. From projects on interstate highways to a single concrete slab at a residence, our process is so cost-effective, that no job is too big or too small


Mudjacking is usually less expensive than polyjacking, due to the cost of the foam materials. Over the years, mudjacking has gained a negative outlook, mostly due to the concrete re-sinking after it's been raised. This most likely is a result of other companies taking shortcuts, by not drilling the proper amount of holes, and pumping in the proper amount of material. Concrete Lift & Stabilization will never shortcut any mudjacking job, for we understand the importance of each of our clients in protecting their investment. Our process will be sure that the proper amount of holes are drilled, and the material completely fills in the voids, making sure the service will last.
