Polyurethane and mudjacking material will both raise concrete yet are VERY different! Did you know poly raising foams are engineered and manufactured using strict specifications? This special process provides the best repair possible.
Mudjacking muds are not consistent and vary from contractor to contractor. In fact, there are nearly as many different slurries as there are mudjacking contractors. You don’t really know what’s going under your concrete with mudjacking.
When selecting a service provider, it’s important to understand the differences between polyurethane concrete raising and mudjacking. Some contractors marketing tactics contain misleading or incorrect information. Know the FACTS before selecting a contractor.
In our 5-part video series “Polyurethane Concrete Raising VS Mudjacking” we review important facts comparing these two methods:
1. EROSION RESISTANCE
Erosion is a primary reason concrete sinks. Watch this side-by-side testing of Poly vs Mud.
2. MATERIAL STRENGTH
Concrete raising materials should support heavy loads. Polyurethane is used to raise tollways & interstates!
3. INJECTION HOLE SIZE
Raised concrete should look discreet. Watch here for examples on how polyurethane & mudjacking are different!
This video contains myth busting facts on how polyurethane relates to personal health, safety & the environment.
5 – COST COMPARISON
Polyurethane is often CHEAPER than mudjacking. The poly material costs more than mud, but its delivery is far more efficient!
|CHARACTERISTIC||POLYURETHANE FOAM INJECTION||MUDJACKING|
|Material Consistency||Acme's polyurethane concrete lifting utilizes a two-part polymer, precisely blended with sophisticated equipment. The result is the formation of lifting foam consistent with every project.||Mudjacking slurries vary from Mudjacker to Mudjacker. Although there may be exceptions, most contractors do not rely on precise measurements when mixing their slurries.|
|Injection Hole Size||Polyurethane uses a very small injection hole size, ⅝” in diameter - about the size of a dime. After patching it is barely noticeable.||Mudjacking requires much larger holes, typically 1 - 2 inches in diameter. Large holes can weaken the structure and the patches are more noticeable.|
|Injection Hole Quantity||Polyurethane is injected as a thin liquid and travels easily between the slab and subsurface, therefore requiring fewer holes to obtain the required coverage.||Most mudjacking operations utilize a very viscous or thick mixture that is unable to travel as easily as liquid polyurethane.|
|Lifting Material Weight||Polyurethane is very strong yet weighs only about 2 pounds per cubic foot. Slabs are lifted without adding significant weight to the subbase.||Mudjacking slurries weigh about 100 pounds per cubic foot. (Remember, weight contributed to the concrete settling in the first place.) The more weight that is added, the greater chance additional settling can occur.|
|Repair Time||Acme's polyurethane is ready to inject on-demand. Also, with fewer injection points, repairs are completed quickly. This process creates no mess, so clean-up time is virtually non-existent.|
Our polyurethane is cured after about 15 minutes. All lifted structures are ready for use once our work is complete.
|Mudjacking “mud” is made on location by combining water with a dry mixture to form a slurry that is transferred to an injection site. After project completion, the repaired slab and mudjacking equipment often require clean-up, most times on site.|
Mudjacking mud (slurry) typically requires 1-2 days to dry well enough to withstand any considerable weight.
|Water Resistance||Polyurethane foam is an inert substance that is resistant to water and will not wash out.||Depending on material types and mixtures, some mudjacking slurries are more susceptible to erosion than others. In general, mudjacking slurries are more vulnerable to washout than polyurethane.|
|Warranty||Polyurethane provides a long lasting, high-quality repair. We provide a no nonsense warranty without tricky loopholes. Feel free to contact us to learn more.||Many competitor warranties contain fine print that eliminates any real worth to consumers.|
