Why Does Concrete Settle?
Concrete settles for numerous reasons, including poor drainage, bad site conditions, low-quality compaction, and unwanted tree roots. The most common reason we see is when the rainwater or water from gutters washes away dirt from under your sideways and driveways. It creates voids or pockets beneath the concrete surface, which causes it to settle.
Another factor that may allow the concrete to settle is clay-rich soil. The soil expands when it’s saturated with water. Then when the soil dries out, it shrinks. Due to such changes in moisture content, the soil becomes unstable. This instability in the soil makes the concrete move and sink.
Concrete Leveling Using Polyjacking
Benefits of Polyjacking
Fast Acting
15 minutes after injection, the concrete slabs become ready to use. You can walk over the concrete slab or run vehicular traffic.
Minimally-Invasive
The polyjacking process doesn’t require any excavation.
Lightweight
The lightweight polyurethane foam doesn’t contribute to further soil settlement, whereas other processes like mudjacking include heavy materials that make the soil settle.
Environmentally Friendly
The foam used in the polyjacking process doesn’t react with soil or moisture. And it doesn’t add any harmful chemicals to the ground.
Cost-Effective
Once you opt for the polyjacking process, you can save up to 50% of the total cost of traditional concrete slab replacement.
Waterproof
Once the process is done, the polyurethane foam won’t wash away or get affected by water.
