What Is Polylifting?
In the past few years, polylifting has become the preferred method of lifting concrete slabs, sidewalks, driveways, and stoops. But what is polylifting exactly, and how does it differ from mudjacking, the more conventional service that performs the same function?
Like mudjacking, polylifting also injects a substance underground to lift concrete, but whereas mudjacking uses a cementitious grout, polylifting uses a polyurethane foam. The two substances ultimately accomplish the same goal, but the grout used in mudjacking takes a full day to cure, and is prone to water erosion and over time can wash away, causing the concrete to sink again. On the other hand, the polyurethane foam cures within 15 minutes, and once cured, the foam is impervious to water erosion. Polyurethane is also strong enough to resist rodent and insect infestation so, not only is polylifting a more efficient ground remediation process, but it’s also more effective in the long run.
Polylifting Uses a Scientifically Formulated Polymer
Well-compacted soil provides a solid foundation that is fundamental to the lifespan of concrete slabs. However, erosion, soil decomposition, and groundwater migration break down this foundation over time, causing 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 ground to provide the support that concrete needs. In fact, 1 square foot of cure polyurethane foam can support a load of more than 10,000 pounds.
