Mudjacking is the typical service we offer to repair settlement issues. Literally, we use “mud”—a slurry of water and non-shrink grout—to “jack” up the sunken concrete slab. First, we drill a set pattern of holes into the sunken concrete slab. Then, we use a Mudjacker to pump the non-shrink grout through the holes. The grout fills voids, raises the concrete slab and stabilizes it. Mudjacking is the most effective way to save concrete slabs by raising them back to the proper level and grade.
There are many different varieties of non-shrink grout, and not all grouts are appropriate for all situations. Based on training and experience, Concrete Pressure Lifting, Inc. selects the best-suited grout for each specific assignment. Our preferred all-purpose grout is agricultural lime, because it maintains flexibility over time and it is environmentally friendly. Agricultural lime is superior to “cheaper” alternatives, such as calcium carbonate and swamp silt. Pure calcium carbonate and swamp silt have a tendency to dry out and break down over time, which may cause a reoccurrence of the original problem.
Mudjacking can repair:
- Garage Floors
- Pool Decks
- Stoops & Steps
- Basement Floors
- Warehouse & Factory Floors
- Bridge Approaches
- Curbs & Gutters
When is mudjacking necessary?
Over time, the weight of the concrete pushes down on the soil underneath, causing the ground to “compact,” or become more dense. As an illustration, this process is similar to what happens to your pillows over time: when you buy them, they are thick and fluffy. Hwever, over time they compact, which makes them thinner and harder. As the soil compacts, the concrete resting on top of it will sink. Because of varying soil conditions and drainage patterns, the areas under the concrete slabs will compact to different densities, which creates uneven concrete. Going back to our pillow analogy, it is common for pillows to be very thin in the middle (where your head rests at night), and be thicker at the edges. The same variability in pressure and drainage in the ground leads to uneven concrete.
In this “before” image, there is a significant gap between the building and the concrete sidewalk. Over time, this gap will lead to increased erosion, as well as potential water damage to the foundation of the house. The sidewalk beside the building is also uneven, which creates a tripping hazard.
After mudjacking, the sidewalk is even and flush with the building. As part of the process, we applied sealant to help prevent future erosion and water damage. The entire process was completed in a matter of hours, with minimal mess and disruption. Best of all, the newly-repaired surface can be used immediately!
As mentioned above, compaction refers to making the soil more dense. While compaction can lead to settlement issues, there are also times when compaction is good. Using the same process described above, we can pump grout in stages directly into the soil. Compaction Grouting is a method to increase soil density by injecting grout in stages into the ground. The grout displaces the surrounding soil. Since the soil is more dense, it is less-likely to further compact under weight, which is important for building stability. This process is appropriate for:
- Foundation Settlement
- Sinkhole Repair
- Pre-Construction Soil Stabilization
Caulking & Joint Repair
It is important to fill cracks and holes in concrete and masonry. For one thing, cracks and holes can lead to problems such as:
- Water Seepage and Leaking
- Leaky Basements
- Ice Heaves
Cracks and holes are also unsightly and as a result, may lower property value. Concrete Pressure Lifting uses our expertise to choose the best caulk for all your masonry repair.
In addition to traditional mudjucking techniques, our company also specializes in tuck pointing. Also known as “repointing,” this method repairs cracks in mortar. In order to prevent erosion and water damage, choose tuck pointing to repair:
- Garage Walls
- Brick Walls
- Retaining Walls
