Your St Louis Polyjacking & Concrete Leveling Experts
Polyjacking, also known as polyurethane foam injection or poly leveling, is a modern, high-performance solution for lifting and stabilizing sunken or uneven concrete surfaces. This advanced process involves injecting an expanding, structural polyurethane foam beneath a settled slab through small, dime-sized ports. As the foam expands, it fills the voids below the concrete, raises the slab back to its original position, and locks it in place — often in a matter of minutes.
Lifting the Standard: Discover the Advantages of Polyjacking
One of the significant advantages of polyjacking is its lightweight, high-strength polyurethane foam, which lifts and supports your concrete without adding significant weight to the very soil that settled in the first place. This makes it an ideal choice for unstable or moisture-prone ground. The foam is also waterproof, so it won't wash out or erode over time, delivering long-lasting, durable results. The process itself is fast, clean, and minimally invasive, using injection holes far smaller than traditional methods and curing quickly, so you can typically walk or drive on the surface within hours rather than days. Whether your concrete has settled due to soil erosion, poor compaction, washout, or shifting St. Louis clay soils, polyjacking restores both functionality and aesthetic appeal to your outdoor and indoor spaces, making it a smart choice for homeowners and property managers looking to address uneven concrete surfaces.
Issues that can be resolved by polyjacking include:
- Uneven concrete slabs
- Settling driveways
- Settling sidewalks
- Sinking garage slabs
- Settling front porch
- Sunken patios and pool decks
By choosing polyjacking over traditional concrete replacement, you can save time, money, and minimize disruption to your daily life. With its lightweight, waterproof, and fast-curing properties, polyjacking is a smart, forward-thinking choice for homeowners and property managers looking to maintain and enhance the beauty and functionality of their concrete surfaces.
