ADA, OK – PowerLift Foundation Repair’s method of polyurethane foam injection lifting of sinking concrete slab surfaces is growing in popularity as a cost-effective and environmentally-friendly alternative to the traditional method of demolition and replacement, as well as other injection methods. This method has multiple applications in residential, municipal and commercial markets, including, concrete slab lifting of sinking driveways, sidewalks, in residential applications and in municipal and commercial surfaces, like parking lots, roadways, and airport runways, etc. That makes, it a smarter, faster, stronger method of raising concrete slabs with many attributes:
- Faster: Polyurethane concrete raising is 80% quicker than other injection repair methods. The material hardens in minutes, allowing repairs to be completed in hours instead of days and weeks of traditional methods. This rapid curing time of high-density polyurethane foam can allow public use immediately after the completion of the injection process. Foam injection requires smaller injection holes of 3/8”, compared to 1”, or greater for alternative concrete lifting methods.
- Smarter: Foam raising provides unsurpassed precision with an accuracy rate of 1/100th of an inch. Other repair methods must take shrinkage into consideration, but polyurethane foam expands and is more controllable with its quick drying characteristics. PowerLift’s material is specifically formulated to resist wet conditions, as it’s hydrophobic qualities repel water without compromising integrity.
- Stronger: PowerLift’s polyurethane foam has a huge advantage over other material, as it provides a solid dense void platform that permantly supports the slab, of which its tensile strength and elongation allows it to be tough and pliable under heavy workloads. The foam has the unique ability to expand 20 times its liquid volume, which allows it to move laterally beneath pavement filling all voids and support the concrete slab with 100% coverage. Foam seeps into the sub-base of the concrete binding soil particles together, which strengthens the material base and creating an additional compounding effect during the lifting process and adds durability.
- Smarter Weight: Other injection methods, such as mudjacking grout, can weigh down the sub-base up to 100 lbs. per cubic foot, as compare to polyurethane foam, which only contributes about 3 to 5 pounds per cubic foot.
Whether the application is raising a sinking driveway, or sidewalk in a neighborhood; a highway section on the interstate; or a runway at the airport, high-density polyurethane foam is a faster, smarter, and more cost effective and environmentally friendly way to get the job done.
