You know how unsafe and unsightly uneven or sunken concrete can be. Water erosion, poor soil stability, tree roots, and earthquakes are some of the causes of sinking or uneven concrete. When concrete settles or sinks, it can also negatively affect the curb appeal of your home. It is possible to quickly and easily repair it using a process called mud jacking. Mud jacking is effective for raising concrete on porches, decks, patios, walkways, basement and garage floors, and driveways.
Mud jacking, also known as slab jacking, concrete lifting, and slab leveling, is an easy and inexpensive technique that is perfect for fixing certain settlement issues with your concrete. It is the process of lifting concrete slabs that have settled by drilling holes through them. Then a mixture of water, soil, sand, and cement called mud or slurry is pumped beneath the settling slab to lift it. The mixture cures to create a solid, stable fill that stabilizes the slab back to its original location.
When used to repair a settling home foundation, mud jacking is a professional job that requires using special equipment. All work should be done by a trained contractor, like the experienced staff you’ll meet at Perma-Pier, who has expert knowledge of local soil conditions and their requirements.
Mud jacking has two primary applications for repairing a foundation:
- Fill Voids: Foundation problems are usually caused by the perimeter of the foundation settling. A foundation contractor will level settled sections of a foundation with push piers. When the piers are installed under the perimeter grade beam and the foundation is raised, it creates a void under the slab. Mud jacking fills the empty space beneath the footing created by this lifting. The foundation contractor uses mud jacking to fill this void by drilling 2″ holes through the perimeter grade beam and pumping a mixture of soil/cement mud into the void.
- Raising Interior Floors: Sometimes the interior portion of the slab foundation settles. Mud jacking is one method used to return the interior floors to their original position. Mud jacking to raise interior floors is done using the same process: drilling 2″ holes through the slab in the areas that have settled and pumping a mixture of slurry underneath the concrete, lifting the slab back to position.
There are several benefits to using the mud jacking process:
- Mud jacking work can be accomplished in any kind of weather.
- Mud jacking is a quick process when compared to the more traditional rip-and-replace approach where the contractor breaks up the concrete, then removes and replaces it. Depending on the size of the job, mud jacking can be completed in as little as a few hours. Larger jobs can take as much as a day. In fact, most the time the work is finished in one day.
- Mud jacking permits almost immediate use. For example, after mud jacking, the slurry takes between 24 and 48 hours to cure before bearing any load. It takes replaced concrete at least 28 days, almost a month, to cure before it available for use.
- While every situation is different, on average, mud jacking is more cost-effective than replaced concrete.
- Using the mud jacking process protects your home’s curb appeal because its installation usually causes no damage to the lawn. In addition, keeping the old slabs of concrete in place ensures the color is consistent.
- Mud jacking is also easier on the environment since there is no cement to dispose of.
