Mud Jacking

Mud jacking, also referred to as slab-jacking or concrete leveling, is used to correct settlement issues in interior and exterior concrete slabs, such as driveways, sidewalks, and porches. If your concrete is sinking there is a very good possibility that the concrete slab was installed on poorly compacted fill dirt. Often Sub-surface erosion and shrinking soils are the culprits.

The mud jacking process includes drilling a 1 ¾” hole through the concrete, and injecting an engineer designed grout mixture under the slab, consolidating the problem soil, filling all voids and then raising the slab.

Mud jacking has been a common repair throughout the upper Midwest for many years. The concept is simple, but should only be attempted by professionals. Mud jacking requires experience and specialized equipment to do the work properly.

There are numerous benefits to mud-jacking:

  • Mud-jacking is a GREEN repair as it reduces concrete that has to go to landfills
  • It can be done in virtually any weather. The material injected beneath the slab provides a strong base.
  • Little or no disruption to landscaping.
  • Nothing needs to be moved off the slab, as the pump can lift the weight of the slab and anything you have placed on it.

 

Pictorial overview of Slab Jacking

1 3/4″ holes are drilled through the sunken slab.
A engineered grout mixture is pumped under the slab with our specialized equipment. Once any void is filled, the grout becomes pressurized, hydraulically raising the slab to the desired height. The holes are patched using a concrete mixture.
