Polyjacking is the smarter way to raise sunken concrete. It’s quick, clean, and permanent—without the demolition mess of traditional methods. Our Charlotte-based team delivers proven results for driveways, sidewalks, patios, and more.
Also known as polyjacking, this concrete leveling method involves injecting expanding foam beneath sunken concrete. As the foam expands, it fills voids and lifts the slab back to its original level.
Compared to mud jacking, polyurethane foam is lightweight, quick-setting, and highly durable—making it the smart choice for residential and commercial concrete repair.
Uneven concrete is often caused by soil erosion, moisture loss, or poor compaction. These conditions create gaps beneath the slab, leading to settling and cracking. Foam injection offers a fast, non-invasive solution. While polyjacking addresses the voids beneath your slabs, our team also integrates specialized foundation crack repair if we find that sinking concrete has pulled away from your home’s perimeter, ensuring your entire structure remains stable.
Our 4-step foam lifting process is efficient, clean, and provides long-lasting results—without demolition.
Step-by-Step Process:
Technicians begin by drilling small, strategically placed holes (typically 5/8" in diameter) into the sunken concrete slab. These holes serve as entry points for the polyurethane foam.

A specialized polyurethane foam is injected through the drilled holes. As it expands, the foam fills voids beneath the slab, providing lift and stabilization

Technicians closely monitor the lifting process, making real-time adjustments to ensure the slab is raised evenly and to the desired level.

Once the slab is properly leveled, the injection holes are filled with a durable patching material, restoring the surface's appearance. Leveling your exterior slabs is a critical first step in moisture management; by sloping concrete away from the home, we assist in waterproofing basement cracks by preventing surface water from pooling and seeping into the foundation's interior.
