Mudjacking for Concrete Leveling in Kansas City
When soils shift and settle, your property’s concrete slabs can be compromised, causing cracks and uneven surfaces. Unlevel concrete can be both hazardous and unsightly, which is why most home and business owners choose to make repairs sooner rather than later. Instead of pouring new concrete, which can be a time-consuming and expensive endeavor, we recommend concrete leveling. Our preferred method of concrete leveling is mudjacking, a process used to level, raise, and fill voids under the concrete.
Why does concrete sinking occur?
The most common cause of concrete sinking is the movement of soil beneath the slab. Over time, soil will naturally settle, though several factors can accelerate this process. Poorly compacted fill soil, washout due to heavy rain or plumbing leaks, and unusually dry weather can all cause soil to shift suddenly and create voids underneath concrete slabs. The strength of your concrete slab depends on the stability of the soil beneath, so when voids begin to form, your concrete will weaken and eventually crack and collapse into the void. Though heavy rainfall and natural settlement are uncontrollable, here are some of the common and often preventable causes of sinking concrete:
- poor soil compaction during construction
- poor excavation for drainage
- poorly installed or maintained downspouts
- burrowing animals
- tree roots
What is mudjacking?
Mudjacking involves drilling holes in the damaged concrete and filling them with “mud,” a mixture often composed of cement and sand. This mixture fills the voids between the concrete and soil, which in turn lifts the concrete surface. Once the slab is raised to the desired height, the holes are plugged with a shrink-proof mixture. You might have heard mudjacking called other popular terms, such as concrete lifting, slabjacking, and concrete raising, but all have the same goal of concrete leveling.
Why is Mudjacking the Preferred Method for Concrete Leveling?
Mudjacking is our preference for concrete leveling because it’s a cost-effective alternative to tearing out and replacing sunken concrete slabs and other concrete repair methods. It is completed in just a few hours, requiring less equipment and manpower than newly poured concrete slabs. Not only that, it’s minimally disturbing to the surrounding areas, meaning less mess and potential damage. Once the mixture is cured and the process is complete, you’ll be able to use your concrete immediately with trip hazards gone and the peace of mind knowing that your concrete repair will last for years to come.
Mudjacking v. Concrete Replacement
When it comes to concrete leveling, mudjacking is a preferable and cost-effective choice over total concrete replacement when the current concrete can be still salvaged. (Tear out and replace is a more expensive option, but ultimately provides you with a brand new concrete slab.) Mudjacking allows you to address only the areas of the concrete that require maintenance, whereas concrete replacement requires you to tear out and repour the entire slab. Concrete contractors can take up to multiple days to complete your new slab given the extensive process, which can include removal, framing, pouring, cutting, and curing. Not to mention, a full tear out and replacement can cost 6 to 8 times more than the cost of concrete leveling.
Mudjacking v. PolyFoam Injections
Mudjacking has been a proven concrete leveling solution for decades and has been around far longer than poly-leveling. In addition, mudjacking is a far more cost-effective solution—foam leveling can sometimes cost almost as much as total or partial concrete replacement. Finally, given concrete’s PSI, it has the ability to lift tougher loads than polyfoam.
