Can you do Mudjacking yourself?

Lifting a sunken slab may be necessary to level the surface. Hiring a professional service to lift, or jack up, the slab can be costly. You can avoid this expense if you do it yourself with the help of a jacking pump, which can raise the concrete slab to the needed level.

How is Mudjacking done?

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.

Can Mudjacking be done in the winter?

Presenting excess water in a cold or freezing environment can be extremely hazardous. Most mudjacking is limited to outside work due to the level of intrusion and the possibility of “blow out”, and therefore little if any mudjacking is done in the winter time.

How do you lift a concrete slab?

Mud jacking can lift a settled concrete slab by pumping a grout through the concrete and pushing it up from below. The process is sometimes called “slab jacking” or “pressure grouting”. 1 to 1 5/8th inch diameter holes are drilled through the sunken concrete block/slab at strategic locations to maximize lift.

Why is my concrete driveway lifting?

Why Concrete Rises
There are a few different causes of rising concrete, and one of them is roots. Snaking and bulging roots can work their way under your concrete and push it up over time. Roots can cause cracks, misplaced slabs, and other headaches. Another common reason for rising concrete is poor soil conditions.

How long does a foundation repair last?

You'll probably have to do it all over again in 3-10 years and foundation repair is more expensive the second time. We repair at least one home a week that has previously been repaired using concrete piers and we don't want that to happen to you.

Do it yourself raise concrete?

Drill 2-inch holes into the sunken concrete and pour a mixture of fly ash, sand, water, and cement into the holes with a pump that produces 50 to 100 pounds of pressure. The mixture, which is like thick mortar, easily raises the sunken slab.
