Why Does Concrete Settle?
Concrete may settle for multiple reasons like poor drainage, low-quality compaction, bad site conditions, unwanted tree roots, and more. The most common reason is when rainwater and water from the gutter wash away dirt from under your concrete surfaces like sidewalks or driveways. It creates voids or pockets underneath the concrete, causing it to settle.
Concrete may also settle if there’s clay-rich soil under the slab. The soil expands and shrinks according to its moisture level. It expands when saturated with water and contracts when it dries out. This frequent instability in the soil 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 can also support vehicular traffic.
Minimally-Invasive
The process doesn’t require any excavation. It ensures 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 inert foam neither reacts with soil or moisture nor seeps any harmful chemicals into the ground.
Cost-Effective
The polyjacking process saves up to 50% of the total cost of any traditional concrete slab replacement process.
Waterproof
Once the process is done, the polyurethane foam won’t wash away.
