Why Does Concrete Settle?
Concrete may settle for multiple reasons like poor drainage, low-quality compaction, damaged site conditions, tree roots, and more. The most common reason is when water from gutters or rainwater removes dirt from concrete surfaces like sidewalks or driveways. It creates voids or pockets into the concrete, which causes it to settle.
Concrete may also settle if there is clay-rich soil. When the soil is saturated with water, it expands. Then, when the soil dries, it contracts. Thus, the soil remains unstable, which causes concrete to move and sink.
Concrete Leveling Using Polyjacking
Benefits of Polyjacking
Fast Acting
Within 15 minutes of injecting the foam, your concrete slab will be ready to use. You can walk on it. It will also be able to support vehicular traffic.
Minimally-Invasive
The polyjacking process doesn’t need any excavation. Hence, it ensures no mess around your concrete.
Lightweight
The foam used in the process is lightweight. It doesn’t contribute to future soil settlement, unlike the heavy ingredients used in solutions like mudjacking.
Environmentally Friendly
The inert polyurethane foam neither reacts with soil or moisture nor seeps harmful chemicals into the ground.
Cost-Effective
The polyjacking process saves up to 50% of the total cost of traditional concrete slab replacement methods.
Waterproof
Once the process is done, the polyurethane foam doesn’t wash away.
