Why Does Concrete Settle?
Concrete may settle due to poor drainage, low-quality compaction, damaged site conditions, tree roots, and many other reasons. The most common reason is when water from gutters or rainwater washes away dirt from under concrete sidewalks or driveways. It creates voids or pockets underneath the concrete, which causes it to settle.
Your concrete may also settle if there is clay-rich soil. The soil expands when it’s saturated with water. Then, when the soil dries, it contracts. Thus, the soil remains unstable with changing moisture levels, which causes 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 it. It will also be able to support vehicular traffic.
Minimally-Invasive
The polyjacking process doesn’t need any excavation. Therefore, it ensures no mess around your concrete.
Lightweight
The lightweight foam used in the process doesn’t contribute to future soil settlement, unlike the heavy ingredients used in solutions like mudjacking.
Environmentally Friendly
Polyurethane foam is inert and won't react with soil or moisture; it won't leach harmful chemicals into the ground.
Cost-Effective
The polyjacking process saves up to 50% of the total cost of any traditional concrete slab replacement method.
Waterproof
Once the process is done, the polyurethane foam doesn’t wash away.
