Mudjacking or Polyjacking in Kansas City?
Sinking and settling foundations lead to some serious structural damage in both the exterior and interior of your home. That is why it is vital that you have a sinking foundation repaired immediately. One of the ways to do this is known as concrete leveling. There are a few different ways that concrete leveling is done, with the two main methods being mudjacking and polyjacking. Pro Foundation Technology of the Kansas City area offers concrete leveling services to keep the foundation under your home level and repair any damage caused by a settling foundation.
In order to determine how to best fix the settling foundation in your home, you must determine which is the better option - mudjacking, or polyjacking? To do this, the differences between the two methods need to be examined. How do mudjacking and polyjacking work, what are the differences, and what are the advantages and disadvantages?
Mudjacking:
Mudjacking is a process that involves pumping a concrete grout material underneath the foundation to lift and stabilize the concrete, filling voids in the soil. First, holes are drilled in the slab. The holes are drilled in strategic locations throughout the concrete to maximize lift. Then, the grout is injected through the holes to fill spaces in the soil beneath the slab. Once the spaces are filled, more grout is pumped into the concrete to slowly lift the foundation in place. Once the slab is lifted, the holes are filled and the equipment is removed. Though mudjacking is less expensive than polyjacking, and offers a substantial amount of compressive strength to the soil, it is a less permanent solution and does not fix the root cause.
Polyjacking:
Polyjacking is performed much the same as mudjacking - holes are drilled in the slab, the material is injected, and the holes are filled when the slab is raised. However, the material being injected beneath the foundation is much different. In polyjacking, an expansive polyurethane foam is used instead of a heavy grout. This material is much lighter than the grout in mudjacking, and expands to 20 times its liquid volume. This allows the grout to not only fill all of the gaps and voids in the concrete and lift the foundation but to also compress the soil around the foundation, which helps to create a more solid overall base.
Benefits of Polyjacking for Concrete Leveling
Traditional mudjacking may be a solution for some less severe foundation settlement issues, but polyjacking offers several clear advantages over mudjacking:
Better accuracy and coverage (within 1/32")- Waterproof solution
- Will not shrink
- Water repellant
- Smaller injection holes (5/8")
- Lightweight material (125-250 lbs per yard, while mudjacking grout is around 2,500 lbs per yard)
- Eco-friendly
- Does not stress foundation
- Fast-curing time
- Expands to fill voids
These are just a few of the benefits of choosing polyjacking over mudjacking for your Kansas City home's sinking foundation.
