Polylifting vs. Mudjacking: Which Concrete Leveling Method Works Best?
Polylifting and mudjacking are two common techniques for lifting the concrete slabs of sidewalks, driveways, and stoops. Like mudjacking, polylifting injects a substance underground to lift concrete, but whereas mudjacking uses a cementitious grout, polylifting uses a polyurethane foam. This foam is impervious to water erosion, making it not only a better long-term solution, but a better concrete leveling method in general. Let’s take a closer look.
Polylifting Uses a Scientifically Formulated Polymer
Well-compacted soil serves as a stable platform for concrete slabs. However, soil erosion and groundwater migration weaken the soil, which then causes concrete slabs to sink or settle. Polylifting solves the problem by eliminating the cause. Injected into loose soil, voids, and water pathways, polyurethane resins strengthen the soil, leveling the concrete slab in the process.
Polylifting Is an Efficient Ground Remediation Process
Polylifting achieves the same results as traditional mudjacking, but polyurethane foam requires smaller and fewer injection holes. About 15 minutes after being injected, the foam cures, then expands before hardening completely, effectively stabilizing the concrete slab.
Simply put, polylifting can be performed faster than mudjacking, and with less mess.
Polylifting Provides Strong Support for Concrete Slabs
The polyurethane foam used in polylifting is remarkably strong. For instance, 1 square foot of cured foam can support a load of more than 10,000 pounds. Moreover, in addition to erosion, the foam resists chemical decomposition, as well as insect and rodent infestation.
