Why Does Concrete Settle?
There are multiple reasons why concrete settles. Some of them are poor drainage, low-quality compaction, bad site conditions, and tree roots. The most common reason is when water from gutters or rain washes away dirt from under concrete sidewalks or driveways. This creates voids or pockets underneath the concrete, which causes it to settle.
Another reason why concrete may settle is clay-rich soil. The soil expands when it’s saturated with water. Then, when the soil dries, it shrinks. This instability in the soil causes your concrete to move and sink.
Concrete Leveling Using Polyjacking
Benefits of Polyjacking
Fast Action
15 minutes after injection, your concrete slab will be ready to use. You can walk on it and it will also be able to support vehicular traffic.
Minimally-Invasive
The polyjacking process doesn’t involve any excavation. You won’t have to deal with any mess around your concrete.
Lightweight
The lightweight polyurethane foam doesn’t contribute to future soil settlement, unlike the heavy ingredients used in solutions like mudjacking.
Environmentally Friendly
The polyurethane foam neither reacts with soil or moisture nor adds harmful chemicals to 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.
