Why Does Concrete Settle?
Some of the reasons why concrete settles 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 surfaces like sidewalks or driveways. This creates voids or pockets beneath the concrete causing it to settle.
Another reason is clay-rich soil. The soil expands and contracts according to its moisture level. It expands when it’s saturated with water. Then when the soil dries, it shrinks. This makes the soil unstable, causing your concrete to move and sink.
Concrete Leveling Using Polyjacking
Benefits of Polyjacking
Quick action
15 minutes after injection, your concrete slab will be ready to use. You can walk on it. It can also support vehicular traffic.
Minimal invasion
The polyjacking process doesn’t need any excavation. So you don’t have to deal with any mess around your concrete.
Lightweight
Polyurethane foam is lightweight and doesn’t contribute to future soil settlement, unlike the heavy ingredients used in solutions like mudjacking.
Eco-friendly
The polyurethane foam used in polyjacking, neither reacts with soil or moisture, nor adds harmful chemicals to the ground.
Cost-Effective
The polyjacking process costs around 50% less than the total cost of traditional concrete slab replacement methods.
Waterproof
Once the process is done, the polyurethane foam doesn’t wash away.
