Polyurethane and “mudjacking” both provide alternatives to concrete replacement which helps keep concrete out of landfills. Acme Concrete Raising & Repair uses sophisticated, concrete lifting equipment & materials. Polyurethane Foam Injection is a clean, efficient, cost-effective and timely way to raise concrete. Made from recycled materials, this state-of-the-art process also results in zero waste, just a few of the many benefits Mudjacking cannot provide. Mudjacking might still be offered by some contractors, but it cannot compare to Acme’s modern polyurethane process.
We understand the importance of making informed decisions. At Acme Concrete Raising & Repair, we want you to be confident with your decision. If you have any questions, please do not hesitate to contact us and one of our professional staff members will be happy to answer them for you. There are many differences between raising settled concrete with Acme’s Polyurethane Foam Injection versus old mudjacking ways. Below we have summarized facts for you in the table below:
|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 days to “set-up” 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 type and amount, some mudjacking slurries may be more susceptible to water intrusion and erosion than others. Frost heave and cracking are also concerns.|
|Warranty||Polyurethane provides a long lasting, high-quality repair. We provide warranties for up to 2 years. Feel free to contact us to learn more.||Many mudjackers only warranty their work for 1 year.|
