Raising Sinking Asphalt Roads
When roads sinks due, it is attributed to soil erosion or other causes. Polyjacking can be used to lift it back into place. When asphalt sinks, it’s often because the underlying dirt was not properly compacted, or because the fill dirt contains debris (such as tree stumps) that are decomposing and collapsing underground. However, there can be some other causes:
- Soil erosion due to improper rainwater drainage.
- Underground collapse or erosion due to a broken buried pipe or underground stream.
- Unstable marshland
- Expansive soil
- Hillside erosion
At Don Kennedy and Sons, we use polyjacking, which is similar to mudjacking, but polyurethane foam is being injected instead of grout. The polyurethane foam mixture is more effective at raising asphalt and concrete slabs.
