About Saint Louis Polyjack
STL Polyjack is a concrete lifting and structural repair company serving homeowners, businesses, and property managers throughout the St. Louis area. With over a decade of experience, our team has completed more than 1,200 residential and commercial jobs across the region. We specialize in polyurethane concrete leveling, foundation repair, and waterproofing solutions that restore stability without the cost and disruption of replacing concrete.
Uneven concrete is a common problem across St. Louis. Soil movement, water erosion, and natural settling can cause slabs to sink over time—leading to trip hazards, drainage issues, and structural concerns around homes and buildings. We use advanced polyurethane foam injection to lift and stabilize concrete safely and efficiently.
Instead of tearing out and replacing slabs, our process raises the existing concrete from underneath. This allows us to fix sinking driveways, sidewalks, patios, garage floors, pool decks, and commercial slabs—saving property owners time, money, and unnecessary disruption.
Our Approach
At STL Polyjack, our goal is simple: fix the problem correctly and make the repair last.
We focus on identifying what caused the concrete to sink in the first place. Voids under the slab, weak soil, or water infiltration often contribute to settlement. By addressing these underlying issues while lifting the concrete, we create a stronger and more stable surface.
Our polyurethane foam expands beneath the slab to fill empty spaces, strengthen weak soil, and gently lift the concrete back to the proper level. The material is lightweight but extremely strong, helping prevent future settlement.
Most projects can be completed in just a few hours, and the surface is typically ready to use right away.
