How Concrete Leveling Works

The A-1 Concrete Leveling Johnson City 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 it's simplest form, we fill any void under your slab with a 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

  1. Small holes (1 inch diameter) are drilled through the sunken concrete block at strategic locations.
  2. 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.
  3. During the last step, the holes are filled with non-shrinking grout leaving the slab looking nearly new.
