Concrete Lifting and Leveling Before & After Photos

Sunken and uneven patio slabs began to create both safety concerns and aesthetic issues for a homeowner in Staten Island, NY. The underlying issue was ongoing concrete settlement, likely caused by shifting soil or water erosion beneath the slab. As the problem worsened, the homeowner turned to Quality 1st in search of a permanent solution. Our team conducted a full inspection of the affected area to determine the extent of the damage and identified the ideal remedy: our patented PolyLevel Foam Injection system.

Using this advanced method, our crew carefully drilled small holes into the sunken slabs and injected high-density polyurethane foam underneath. The foam expanded to fill voids in the soil, gently lifting the concrete back to a safe and even position. The process was quick, non-invasive, and far more efficient than traditional methods like mudjacking or full replacement.

Once the repair was complete, the patio surface was level and stable, giving the homeowner a restored outdoor space and peace of mind that the problem was resolved for the long term!

This homeowner from Staten Island, NY noticed settling concrete in their walkway. They called Quality 1st Basements for a free quote. One of our System Design Specialists recommended Polylevel to lift and level the sunken concrete. The Polylevel foam is injected under the slab and expands until the slab is level with the rest of the walkway. The homeowner can now have peace of mind that their walkway is free of trip hazards. 

Settling concrete slabs around a backyard pool deck in Staten Island, NY prompted safety concerns for the homeowner as shifting soil and water intrusion caused the surface to sink, creating hazardous walking conditions. Focused on restoring both safety and functionality to their outdoor space, the homeowner reached out to Quality 1st for a professional assessment.

Our team conducted a detailed evaluation to identify the root causes and severity of the settlement, enabling us to develop a customized repair plan tailored specifically to their needs.

To correct the issue, we utilized our patented PolyLevel Foam Injection System, injecting a lightweight polyurethane foam beneath the affected slabs. The foam expanded to fill voids and gently raised the concrete back to a level, stable position with minimal disturbance to the surrounding area. This precise lifting and stabilization process effectively eliminated tripping hazards and enhanced the deck’s overall appearance.

The project resulted in a smooth, safe, and durable pool deck, restored to provide lasting value and enjoyment for the homeowner!
