Polyjacking VS. Mudjacking for Concrete Leveling

When it comes to concrete leveling there are many benefits regardless of the method used to achieve the result. Concrete leveling can eliminate tripping hazards, stabilize settled concrete, prevent the need for concrete replacement, and provides minimal evidence of the repair on the top of the slab. However, this is about where the two main methods for concrete leveling end.

Mudjacking is a concrete leveling technique that uses sand, cement, and other materials to raise and level a concrete slab. These materials are mixed into a slurry and pumped underneath the slab through holes drilled in the areas where settlement has occurred. Mudjacking works best for concrete that is in good condition but is no longer level. However, there are some projects where Mudjacking is not the best choice. It won’t work for slabs that are heavy, too large, or load bearing. It can also cause more problems for severely damaged concrete because mudjacking can’t fill every void that may cause settlement.

Polyjacking is a similar method of concrete leveling that involves injecting high-density expanding foam to raise and stabilize concrete slabs. The material and equipment needed is similar to what is used in spray foam insulation; however, the foam used for lifting concrete has higher strength and will withstand harsher weather conditions. Polyjacking is great for small and large repairs and can be used on load bearing concrete slabs because of its superior expansion properties. When injected underneath a slab the expanding foam can reach voids that are hidden or hard to reach without the need to excessive drilling on your slab.

So, why use poly jacking instead of mudjacking to level concrete? The slurry used in mud jacking is not waterproof and can erode over time if water drains along the sides and underneath the slab. Polyjacking will not break down over time. The foam is waterproof, quickly expands and hardens, won’t degrade due to temperature extremes, and has no chemical leaching, so it is environmentally friendly. Polyjacking can withstand more weight and use than mudjacking. Ultimately, poly jacking results in a more polished final product. Fewer resources and heavy equipment are required, so the job site is neater, the surrounding landscape isn’t damaged, and the disruption to your home or business is minimal.

Signs You Need Concrete Leveling

Sinking concrete only gets worse when left untreated. Because the problem develops slowly, issues with your concrete slabs are easy to ignore. Our team at Deska Services knows how important it is to address uneven concrete quickly. Often when a home improvement or commercial project requires backfill, the replaced soil is not properly compacted. Concrete is often poured over the recently backfilled soil which can cause settlement and uneven concrete.

It is important to regularly check areas around your home where concrete has been poured. These areas are the most prone to settlement due to soil erosion, soil compaction, and seasonal soil shrinkage. All of these problems cause invisible voids underneath your slabs which over time can cause both settlement and cracking. Be sure to keep an eye our for small cracks, uneven concrete pads, and settlement around your home or business.
