Roadway Asphalt Leveling
Statewide’s roadway asphalt leveling solution is a no-excavation application that can lift and level roadways, highways, and bridge approaches.
Roadway Asphalt Leveling with Polyurethane
Poor base soils can wreak havoc on roadways, causing issues such as settlement, and breakage. Statewide offers a fast, effective, and minimally disruptive solution for lifting settled roadways.
Polyurethane injection is highly effective for repairing issues that cause roadway settlement. In one application, the polyurethane simultaneously fills voids, densifies soils beneath pavement, and lifts the roadway back to the grade. Polyurethane roadway lifting an excellent solution for restoring soil load-bearing capacity, lifting and leveling bridge approaches, filling voids around manholes and stormdrains, and helping prevent future soil loss.
Benefits of Roadway Asphalt Leveling with Polyurethane:
How Roadway Asphalt Leveling Works
Once injected, the polyurethane aggressively seeks out voids, like how water seeks the path of least resistance. After a few short minutes, the polymer reacts and begins to expand throughout the voids and the weak points in the soil. The polyurethane then begins to use expansive pressure to lift pavement back to the correct position.
Polyurethane is injected through the asphalt
Injections are made through 5/8′ holes that are drilled through the pavement.
Polyurethane begins to expand, packing the voids and weak soils
Once injected, the polyurethane travels throughout the voids and expands up to 25 times its original volume through the soil.
Once the void is filled, polyurethane packs soils and raises the roadway.
After filling voids, the polyurethane continues to expand, compacting and densifying soils to create a solid base. As it continues to expand, the pressure lifts the pavement back to grade.
Why Our Polyurethane Solutions Work
Our polyjacking process is ideal for roadway leveling. Lifting roadways with polyurethane foam is cheaper than replacement and minimizes downtime. Polyjacking is a reliable process used for years by many roadway leveling contractors.
Our polymer injection application is a no excavation rocking slab stabilization solution, allowing for minimal impact to your structure. Our project footprint is minimal, requiring a small trailer, a hose running from the trailer, and small 5/8″ holes that are drilled through the structure to give us access to drive our rods to target locations and inject our high-density polyurethane.
We use polyurethanes that are light-weight, reducing added weight to the area. This is a major advantage because often times treatment is required because a structure’s weight is too much for the geology of the area.
Our polymers set up to 95% capacity within 15 minutes, unlike other solutions which require 24-48 hours and ideal soil conditions. After 15 minutes, the material can be driven on and take on heavy loads
Our polymers are environmentally inert and have no impact to the environment or groundwater.
Not only is our process the fastest and most effective foundation and slab lifting application, but it is the most cost-effective too.
