Mud jacking is an easy, inexpensive technique that is perfect for fixing some settlement issues with your concrete. However, it’s a process that’s often misapplied in the foundation repair industry. Learn about when it’s useful- and when it’s definitely NOT useful in this brief article.

What is Mud Jacking?

Mudjacking Benefits
  • About ½ Cost of Removal/Replacement
  • Long-Lasting
  • Fast, Easy Installation
  • Installs Without Damage to Yard
Mudjacking (also known as slab jackingconcrete liftingconcrete raising, and slab leveling) is a foundation and slab repair technique for lifting settling concrete slabs.
It is also used during larger foundation settlement, but not as a load-supporting part of the structural repair.
Mudjacking consists of pumping a mixture of “mud” or “slurry” underneath a settling slab to lift and stabilize it. This injected material is a mixture of water, soil, sand and cement that cures to create a solid, stable fill.
Uneven or sunken concrete is unsafe and unsightly, but it isn’t difficult to repair. Most often, it’s caused by soils that are compacted by the weight of the concrete (or through water erosion). This is quickly and easily repaired through a process called mudjacking.
During installation, small holes are carefully drilled in the sinking concrete slabs. The slurry is mixed and prepared, and a line is fed into the concrete opening. Once the concrete is raised to the desired level, the hole is patched over and tooled off.

Mudjacking has two main applications:

  1. Stabilizing Settling Foundation Footing or a Perimeter Wall: A foundation contractor will level settled sections of a foundation with push piers, using them to lift the masonry to a level position. When this is complete, mudjacking can be done to fill the empty space beneath the footing created by the lifting.
  2. Stabilizing Settling Concrete Slabs: This is used for non-looad bearing lightweight concrete structures.  The slurry is injected underneath the concrete, lifting the slab back to position.

Especially in the case of a settling home foundation, mudjacking requires special equipment and is a professional job. All work should be done through a trained contractor who has excellent knowledge of local soil conditions and their requirements.

Additionally, mudjacking is not always the right solution for your foundation issue. A foundation contractor or structural engineer can meet with you to asses the problem and help make sure you won’t have to do further work in the future.

Depending on the size of the job, mudjacking can be completed in as little as a couple hours.  Larger, more extensive jobs can take as much as a full day’s work. After mudjacking, the slurry should then be given about 24-48 undisturbed hours to cure before bearing any load.
