The type of slab The Mudjackers raises is referred to as “floating concrete” meaning the concrete moves with the ground. The ground can move as a result of frost and thawing or the amount of moisture present in the soil at different times of the year. Therefore, it is necessary to use material that is able to take on or release moisture at the same rate as the surrounding soil as to float the concrete properly.

When new concrete is installed, a base of compacted sand and/or gravel is used. Logic assumes it would be best to raise the sunken slab with more of the same, but it is not possible to pump pure sand. A pumping aid is needed. Our engineered material is mixed at each job site to adjust for each condition encountered.

Our formulation has enough flexibility to fill voids and pockets. This will result in using more material providing a more thorough complete solution that has a stronger P.S.I. rating greater than a normal base for concrete. Some competitors mixtures are cement based that can set up too quickly. This creates a “pillaring effect” with material established as pillars and leaving voids throughout the affected area.

What are the Benefits of Mudjacking?

Save Money

Our process takes hours, not days, and reduces the amount of down time because you don’t have to wait almost a month for it to cure/dry. You can walk on it almost immediately, preventing any loss of use.

Save Time

Is your patio, driveway, or garage floor cracking and sinking? We can raise and level floating concrete wherever the ground below has experienced shifting due to moisture or frost by injecting material to create a strong new base.

No Waste

Surrounding areas are not dug up which keeps your landscaping intact and because there is no concrete waste ending up in landfills this solution is far better for the environment.

The Mudjacking Process


Small holes are drilled into the concrete slabs.


Material is pumped under pressure thru these holes.


Material displaced voids leveling slab leaving a firm permanent subgrade. Holes are filled.

Common Problems Caused By Sinking Concrete

  • Settled driveways
  • Sidewalk trip hazards
  • Steep slippery slopes on porches and stoops
  • Back pitched concrete next to houses
  • Tilting garage floors
  • Settled pool decks
