what Is Mudjacking?
Mud jacking, also known as slab jacking, concrete lifting, concrete raising, grout pumping, or slab leveling, is a older method used to lift and level settled concrete surfaces.
Mudjacking involves pumping a heavy slurry (usually cement, soil, and water) beneath sunken concrete to lift it. While it can be effective short-term, it’s messy, invasive, and often doesn’t last.
Why PolyLevel® Foam Injection Is Better?
Smaller, Less Noticeable Holes
Smaller, Less Noticeable Holes
When you compare repair sites, you notice PolyLevel® uses much smaller holes than traditional mudjacking. These tiny entry points blend into your concrete and look cleaner once patched. That matters because large holes can weaken the slab and leave more visible repair marks over time. Smaller holes also mean less disruption to landscaping around the slab. The overall finish looks more like the original surface.
Fast Return to Use
Fast Return to Use
With PolyLevel®, the foam cures quickly, often in minutes rather than hours. After work is done, you can walk or drive on the surface much sooner. This matters especially for busy driveways, patios, and walkways. Long cure times delay use and can inconvenience your schedule. A quicker turnaround means less disruption to daily routines.
Stable Soil Support Under Concrete
Stable Soil Support Under Concrete
PolyLevel® foam expands and fills voids beneath the slab, compressing soil and stabilizing the base. That shows on the surface as fewer dips or new settling after repair. In contrast, traditional mudjacking relies on heavy slurry that can wash out or compress further. When soil is stabilized, the slab stays level longer and you avoid repeat repairs. This also reduces the risk of future cracks and uneven spots.
Lightweight Yet Strong Material
Lightweight Yet Strong Material
After installation, homeowners often notice that slabs feel solid without extra weight pushing down. PolyLevel® foam is lightweight but strong enough to support heavy loads. That matters because heavy repair materials can add stress to weak soil, causing more settling later. With a lighter material, the slab stays supported without adding unnecessary downward pressure. That results in a longer lasting fix.
Better Resistance to Water and Erosion
Better Resistance to Water and Erosion
PolyLevel® foam does not absorb water and resists erosion over time. On rainy days or near sprinklers, slabs repaired with foam are less likely to settle again. With traditional mudjacking, water can wash away the repair material, leading to new dips. When water doesn’t undermine the base, your concrete stays level longer and reduces the need for future maintenance.

The Best Solution For The Problem
Cantey Foundation Specialists offers a fast, effective, and less invasive approach to concrete leveling with PolyLevel®. The PolyLevel® system involves injecting an expanding polymer foam under the concrete for a durable, long lasting solution.
PolyLevel® Foam Injection
- Strong but light: PolyLevel® weighs only about 4lbs. per cubic ft., compared to 120lbs. per cubic ft. for standard fill material. PolyLevel®’s light weight makes it useful where denser fill material might impose an undesirable load on weak soils. Despite its light weight, PolyLevel® can support substantial loads; it typically provides greater lifting power than mudjacking.
- Waterproof: Once cured, PolyLevel® will not wash away. PolyLevel®’s waterproofing properties can be beneficial in certain applications.
Stable and inert: PolyLevel® does not react with soil or moisture; it will not leach harmful chemicals into the soil. - Quick curing: Downtime is minimized with PolyLevel® concrete repair. Full loading of the foundation, roadway, or other structural element can usually happen about 15 minutes after the material is injected.
- Adjustable: Adjusting the density and expansive force of the 2-part foam affords a wide range of geotechnical uses. Lifting force can be adjusted by fine-tuning the chemical reaction that causes the foam to expand. An experienced applicator can factor not only the weight of the structural element but also soil characteristics and temperature and weather conditions. Special formulations are possible for applications where water must be displaced.
- Noninvasive: PolyLevel® injection equipment isn’t bulky, enabling applicators to access confined areas. When properly injected, PolyLevel® is not as messy or disruptive as other slab and foundation-lifting techniques.

What is mudjacking?
Mudjacking is a traditional method used to lift sunken concrete by pumping a heavy slurry mixture beneath the slab. The mixture typically includes water, soil, sand, and cement. As it fills empty spaces below the concrete, pressure builds and raises the surface. Once it hardens, it creates a solid fill under the slab. While it can lift concrete, it does not address underlying soil movement long term.
Why doesn’t mudjacking always last?
Mudjacking uses a heavy material that can contribute to continued soil compression beneath the slab. If the soil continues to shift or wash out, the concrete may settle again. The slurry itself can also erode over time with water exposure. Because it does not permanently stabilize the soil, repeat repairs are sometimes needed. This makes it more of a temporary fix in many cases.
How is PolyLevel® different from mudjacking?
PolyLevel® uses a lightweight, expanding polyurethane foam instead of a cement-based slurry. The foam is injected beneath the slab through small holes and expands to lift the concrete with precision. It cures in about 15 minutes and is waterproof once set. Because it is lightweight, it does not add extra stress to unstable soil. This provides a longer lasting and less disruptive repair.
When is mudjacking not appropriate?
Mudjacking is not recommended as a standalone solution for lifting heavy foundation footings or floor slabs inside the home. In many cases, it cannot reliably lift both the slab and the walls resting on it. If the underlying soil continues to settle, the problem will return. More advanced solutions, such as slab piers, may be required in these situations. A professional inspection can determine the right approach.
Why should I choose Cantey for concrete leveling?
Cantey uses proven PolyLevel® technology installed by trained professionals with experience in local soil conditions. The system is designed to provide fast, precise lifting with minimal disruption. Smaller drill holes, quick cure time, and waterproof material all contribute to long term performance. Repairs are backed by written warranties for added peace of mind. Homeowners receive a clear plan tailored to their specific concrete issues.
