What is Mudjacking?

Our concrete raising process also known as slabjacking or mudjacking is a cost effective alternative to replacing settled or sunken concrete. 

Sunken concrete can be caused by a few different factors such as poorly compacted soil during construction, soil shrinkage due to water evaporation during drought conditions and water erosion due to poor drainage from improper routing of gutter down spouts and surface cracks. 

The Problem 
The Solution

Slabjacking or Mudjacking is the process of raising and re-stabilizing concrete slabs that have settled or sunk due to poor soil conditions or soil erosion. It is sometimes referred to as “pressure grouting” as well. 


 Concrete is lifted by drilling small 1 3/8″ holes through the slab, and pumping, under hydraulic pressure, a flowable soil cement slurry. As the slurry flows beneath the surface, voids and depressions are filled and the slab is raised to achieve the desired height.
