Adirondack Basement Systems Before & After
  • Sinking Sidewalk Repair in Schenectady, NY
    Sinking Sidewalk Repair in Schenectady, NY

    Sinking Sidewalk Repair in Schenectady, NY

    The sidewalks in front of a local company's building were sinking, causing potential tripping hazards for their customers.  They needed to be lifted and repaired efficiently so that they wouldn't continue to sink in the future. After seeing our advertisements for PolyLevel they contacted us for a free estimate on the repair.

    PolyLevel is a lightweight polyurethane polymer that is injected into concrete slabs to expand and lift them back to their original position. Soil composition affects the likelihood of a slab sinking. When the soil compacts or is washed out it creates a gap beneath the slab that can cause sinking or cracking due to lack of support. PolyLevel has proven time again to be an ideal solution for concrete slab repair!

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.
