How to raise cracked concrete? Mud Jacking is a common term for lifting sunken or settled concrete. 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”.
Can I raise concrete myself? 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 do you lift sagging concrete? You have three options: coat the sunken section with a sand-and-cement mixture to make the surface higher, raise the sunken section using a process called mudjacking, or raise the sunken section using expanding polyurethane foam. Patching fixes the safety issue without costing much, but the patch is sure to show.
