Concrete leveling in Downers Grove is done using a technique called polyjacking to raise and level sinking concrete slabs, patios, pathways, and driveways. Expanding polyurethane foam is used in this method. In contrast to other alternatives like mudjacking, it is a non-toxic concrete leveling method that operates more quickly and efficiently.
Why Does Concrete Settle?
Various factors, including inadequate compaction, poor drainage, unfavorable site conditions, and tree roots, can lead to concrete settling. It is most frequently caused by rainwater and gutter water washing debris out from under your driveway or sidewalk. This leads to the formation of voids or pockets beneath it, causing the concrete to settle.
Another reason can be the clay-rich soil, which expands and shrinks as per its moisture level. When the soil is saturated with water, it expands, and similarly when the soil is dried, it contracts. Therefore, the soil remains unstable and causes the concrete to move and sink.
Concrete Leveling Using Polyjacking
Concrete should be supported by soil as stable and strong as the concrete itself. Otherwise, it might become difficult for it to support the weight. If the issue is weak soil, the slab cannot be replaced.
Benefits of Polyjacking
Quick Action
Just 15 minutes after injecting the foam, you can easily walk over the concrete slab. The slab is strong and stable enough to accommodate vehicles as well.
Minimally-Invasive
The technique is minimally invasive for homeowners as it does not involve any major construction or digging.
Lightweight
The foam is composed of lightweight polyurethane in comparison to heavy-weight materials used in other procedures such as mudjacking.
Environmentally Friendly
The foam used for polyjacking does not allow any dangerous substances to seep into the ground and fills the voids in the soil.
Pocket-friendly
Owners can save up to 50% of the traditional concrete slab replacement expenses if they opt for concrete leveling by polyjacking.
Waterproof
Polyurethane foam is completely waterproof and not easily weakened by any exposure to water.
