Why Does Concrete Settle?
Poor drainage, bad site conditions, and unwanted tree roots are some of the reasons why concrete may settle. The most common reason is when rainwater or water from your gutters washes away dirt from under the sidewalk or driveway. This creates a void under the concrete surface, which causes it to settle.
Another reason why concrete may settle is due to clay-rich soil. The soil expands and retracts as per the amount of moisture in it. When the soil is saturated with water, it expands. Then, when the soil dries, it shrinks. This instability in the soil causes the concrete to move and settle.
Concrete Leveling Using Polyjacking
Benefits of Polyjacking
Fast Acting
15 minutes after injection, you can walk over the concrete slab. It will also be able to support vehicular traffic.
Minimally-Invasive
The whole polyjacking process doesn’t require any excavation.
Lightweight
The lightweight foam doesn’t contribute to further soil settlement, unlike with other processes like mudjacking, which involve heavy materials.
Environmentally Friendly
Polyurethane foam doesn’t react with soil or moisture. Moreover, it doesn’t add any harmful chemicals to the ground.
Cost-Effective
With polyjacking, 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.
