Concrete Slab Lifting

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.

Benefits of Mud Jacking

Utilizing compaction grouting can help correct the following issues:

  • It’s a green repair since it reduces the amount of concrete sent to landfills.
  • It can be done in nearly any weather conditions.
  • There is close to zero damage to landscaping.
  • Nothing needs to be moved since the pump can lift the slab and other loads on top of it.

Example of Combining Compaction Grouting and Mud Jacking

If a front porch has sagged over time due to loose backfill behind the basement walls, Straight Line Construction can mitigate the settlement issue by performing this process:

  • Drill holes through the slab and drive grout pipes through the holes into the loose soil. Pressure pump grout to displace and compact the surrounding soil until it is stabilized.
  • Lift the sagging slab by pumping low mobility grout just below the surface until the slab returns to as close to its original elevation as possible.
  • Fill any remaining void spaces with a higher mobility grout to prevent future cracking or settlement. Patch holes and clean work area, leaving little evidence of the work performed.

Poly Foam Injection

Sometimes an alternative method to mud jacking is necessary to raise a foundation, backfill, or fill a void under a building. Perhaps an ultra clean method is required, there is heavy foot traffic that cannot be re-routed, or the material being drilled is decorative with a need for minimal disruption.

Polyurethane foam injection in CO, NM and AZ is an effective concrete lifting alternative to mud jacking.

Straight Line’s precision lift foam is designed as a simple, clean placement of expandable foam injected in very small drilled openings to lift a foundation to its original location. The foam is non-hazardous, hydro-sensitive, produces little to no mess to clean up, does not require large installation equipment, has no special disposal requirements, and is a perfect solution for large slabs or locations where there is a need to maintain cosmetic integrity.

About Ram Jack

Ram Jack is a family-owned business that began operations in 1968, in Ada, OK, where we currently source our piers and brackets. Back then, concrete piering was the original repair method used simply because it was the only technology available at the time. Over time, it became evident that concrete piers did not provide long-term stabilization of foundations and only provided a short-term warranty period. To guarantee the highest grade of customer satisfaction, a greater solution needed to be found.

The Ram Jack owners embarked on a research program to develop a foundation repair system to stand the test of time. The U.S. Patent and Trademark Office first issued a patent to Ram Jack for its foundation repair system in 1985. Over the next few years, additional refinements and patents have followed, resulting in the strongest patented system in the industry. Ram Jack driven pilings are ICC-ES recognized (International Construction Code—Evaluation Services). Ram Jack is one of only two ICC-ES recognized foundation repair companies in the industry. Ram Jack’s products meet or exceed code requirements set down by ICC-ES for both commercial and residential properties.
