This customer in Schenectady, New York reached out to us to level a significant crack in his concrete walkway that needed to be safely wheelchair accessible. Choosing our PolyLevel concrete repair system was a no brainer. The PolyLevel lifted and leveled the concrete back to it's original standards and was completed for use within 15 minutes! Pea sized holes were drilled into the slab and then the polymer foam was injected to lift it. PolyLevel is environmentally friendly, waterproof, and can also be used to lift and stabilize roads, bridges, and even railroads.
