Why Does Concrete Settle?
Concrete settles for multiple reasons, including poor drainage, bad site conditions, low-quality compaction, tree roots, and more. The most common reason is when rainwater and water from your gutters washes away the dirt from under your sidewalk or driveway. This forms pockets or voids under the existing concrete, which causes it to settle.
Another reason is when you have clay-rich soil, which expands and shrinks as per its moisture level. When the soil is saturated with water, it expands. Then, when the soil dries, it contracts. Thus, the soil remains unstable and causes the concrete to move and sink.
Concrete Leveling Using Polyjacking
Benefits of Polyjacking
Fast Acting
15 minutes after injecting the foam, your concrete slab will be ready to walk on and support vehicular traffic.
Minimally-Invasive
The process doesn’t require any excavation. Therefore, you’ll find no mess around the concrete surface.
Lightweight
The polyurethane foam used in the process is lightweight and doesn’t contribute to future soil settlement.
Environmentally Friendly
The foam is inert. It never reacts with soil or moisture. It doesn’t seep any harmful chemicals into the ground.
Cost-Effective
The polyjacking process helps save up to 50% of the total cost of any traditional concrete slab replacement process.
Waterproof
Once the process is done, you can be sure that the polyurethane foam won’t wash away.
