A Superior Alternative to Mudjacking

A less disruptive, environmentally friendly method

Mudjacking, also known as slab jacking or concrete jacking, has been the traditional method for lifting sunken concrete slabs, but is it the best method? The process involves boring numerous, large-diameter injection holes, and injecting a slurry of cement and soil beneath the slab. Because the “mud” is hydraulically pumped under considerable pressure, it can lift the offending slab section back to its original position. But if the soil or fill upon which the slab was installed is weak or was poorly compacted, the mudjacked slab will likely go right back to sinking. The fact that the mud adds 100 to 150 pounds per cubic foot doesn’t help matters.

What does mudjacking do?

Mudjacking is a method of raising sunken concrete by hydraulically pumping a slurry of cement and soil, or "mud," underneath through large holes drilled into the concrete slabs.

Is mudjacking a permanent fix?

Not necessarily. In fact, mudjacking adds a lot of weight to the already unstable soil below the slabs - which was the reason they likely failed in the first place. This can cause them to sink further over time.

What are some other names for mudjacking?

While "mudjacking" is the most common term for hydraulic concrete lifting, it can also be known as "slabjacking," "concrete jacking" or "pressure grouting."

What is better, mudjacking or polyurethane?

While mudjacking can be successful, it has serious drawbacks. The process is extremely messy and disruptive and requires drilling large holes in the concrete that remain an eyesore even when patched. The weight of the "mud" can also cause the underlying soils to compress further, resulting in further concrete settlement. Polyurethane foam, on the other hand, is extremely lightweight and can be injected through tiny holes that are barely noticeable when the job is finished. As it expands and solidifies, foam also compresses the soil beneath the concrete, stabilizing it permanently.

What about a mudjacking warranty?

Most mudjacking companies do not offer warranties on their services because there's always a chance the underlying soil will further compress due to the weight of the slurry pumped under the slabs. However, companies that offer PolyLevel® polyurethane foam lifting typically offer a five-year warranty as a part of their Concrete Protection System, which includes sealing the joints with NexusPro® crack and joint sealant to prevent moisture from seeping beneath the slabs.

PolyLevel® Concrete Lifting & Leveling System

Polyurethane foam injection, or the PolyLevel® System, is a superior alternative to mudjacking. PolyLevel® takes the original concept of mudjacking and combines it with modern knowledge and technology. Some of the advantages include:

Light weight: The polyurethane foam weighs only 4lbs. per cubic yard, opposed to 120 lbs. of typical concrete or mud.
Greater lifting power: Although light weight, PolyLevel® can support substantial loads; it typically provides greater lifting power than mudjacking
Precise lifts: Metered, intermittent injections ensure more precise control of the lift. Lifting force can also be adjusted by fine-tuning the chemical reaction that causes the foam to expand.
Soil consolidation: Polyurethane foam can penetrate small voids throughout the underlying soil, strengthening its ability to support weight and reducing the erosion.
No waiting: A PolyLevel® job allows the surface to be put back into service almost immediately. Whereas, traditional mudjacking requires hours or days to cure.
Hole size: Mudjacking holes are often 2-in. in diameter or larger. This can give walkways an unattractive polka-dot appearance after they’ve been troweled over. PolyLevel®’s 5/8-in. dia. injection holes (penny-sized) are almost invisible once they’ve been filled.
