Adirondack Basement Systems Before & After
  • Lifting and Leveling a Walkway in Philmont, NY

    Lifting and Leveling a Walkway in Philmont, NY

    A homeowner in Philmont, NY had a concrete walkway with steps that were unlevel. This caused a safety hazard for tripping and they wanted to have it fixed to ensure nobody would get injured. They contacted Adirondack Basement Systems for a free estimate on our PolyLevel repair system. PolyLevel is an alternative to mud-jacking in that it is lightweight and won't cause future sinking of the slab. It is installed by injecting a polyurethane polymer beneath the slab that raises it. Waterproof and environmentally safe, you never have to worry about it washing out from beneath the concrete and affecting the environment.

    Lifting a Walkway in Albany, NY

    Homeowners in Albany, NY have a concrete walkway leading to their front porch that had sunken significantly. Our PolyLevel system was used to raise it back to its intended position. This was done by injecting a poly-urethane polymer underneath the slabs. This light-weight high-density polymer is a more ideal solution than mud-jacking. Mud-jacking creates more weight beneath the slab and will only make it sink again in the future. It is also waterproof and environmentally friendly so you don't have to worry about it ever washing out.

    Poly Level Repair in Albany, NY

    Mr. F contacted our company with concerns about his front porch creating a tripping hazard due to the concrete slab dropping and leaving a high step to get into his house. Our Design Specialist Tim met with Mr. F to discuss the best solution to this issue, suggesting our patented Poly Level System. Afterwards our foreman Michael came and inserted Poly Level into the concrete ultimately solving the issue and creating a safer porch for Mr. F and his family.

    Our Poly Level System is a state of the art approach to repairing sinking concrete. Rather than using a mixture of concrete and mud, this method utilizes high-density polymers to raise slabs back to a desired level.
