Mud jacking, commonly referred to as concrete leveling or slab-jacking, is used to deal with the effects of settlement in concrete slabs used for driveways, porches, and sidewalks. If your concrete is sinking, the slab may have been placed on under-compacted dirt or there may be a factor such as sub-surface erosion or shrinking soils at work.
Mud jacking involves drilling a hole through the concrete and injecting a specially designed grout mixture under the slab. This mixture consolidates the soil, fills any potential voids, and raises the slab. Despite being a common repair in the upper Midwest for many years, mud jacking should only be attempted by professionals. In order for mud jacking to work properly, the technician performing the work must be experienced and have the proper equipment.
