Concrete leveling in Aurora involves lifting and leveling concrete slabs, patios, driveways, or sidewalks that sink. This process is called polyjacking, in which expanding polyurethane foam is used. It’s a non-toxic concrete leveling method that is faster and more robust than other solutions like mudjacking.
Why Does Concrete Settle?
Concrete settles for many reasons, like poor compaction, bad site conditions, poor drainage, and tree roots. The most common reason for this issue is when rainwater or water from gutters washes away dirt from under your sidewalk or driveway. That creates voids or pockets beneath the concrete, which causes it to settle.
Another reason is clay-rich soil, which expands and contracts as per its moisture level. When the soil is saturated with water, it expands. And when it dries out, it shrinks. Thus, the frequent change in moisture results in unstable soil, which causes the concrete to move and sink.
Concrete Leveling Using Polyjacking
Benefits of Polyjacking
Fast Acting
15 minutes after injection, you can walk over the concrete slab. Also, the slab can support vehicular traffic.
Minimally-Invasive
The process doesn’t involve any excavation or digging.
Lightweight
The polyurethane foam used here is lightweight. It doesn’t contribute to future soil settlement, unlike other methods like mudjacking which includes heavy materials.
Environmentally Friendly
The foam used here is inert and doesn’t react with soil or moisture. And it doesn’t leach any harmful chemicals into the ground.
Cost-Effective
You can save up to 50% of traditional concrete slab replacement costs if you opt for concrete leveling by polyjacking.
Waterproof
Once it’s done, the polyurethane foam doesn’t wash away.
