The Real Seal offers concrete leveling services in and around Joliet, Illinois. Sinking concrete slabs, patios, paths, and roadways are raised and leveled using a method known as polyjacking. This technique involves the use of expanding polyurethane foam. It is a non-toxic concrete leveling technique that works more efficiently and quicker than other alternatives like mudjacking.

Why Does Concrete Settle?

A number of factors, including inadequate compaction, a bad drainage system, unfavorable site conditions, and tree roots, can cause future concrete settlement. This is most frequently caused by rainwater and gutter water washing soil out from under your driveway or sidewalk. This can cause the formation of voids or pockets beneath it, causing the concrete to settle eventually.

Another reason for settling concrete is the clay-rich soil, which expands and contracts according to the moisture content in the soil. When the soil is saturated with water, it begins to expand, and when the soil is dried, it contracts. This is why the soil remains unstable and causes the concrete to move and sink.

Concrete Leveling Using Polyjacking

Soil that is as robust and sturdy as the concrete itself is needed to support the concrete surface. Otherwise, it can be challenging for it to support the weight. The slab can be replaced but it won’t fix the problem with the soil.

Poly Jacking Process

The polyjacking process includes:

Sidewalk lifting foam process

Step 1: Dime-sized holes are drilled in the sunken concrete surface.
Step 2: Polyurethane foam is injected underneath the surface through the hole.
Step 3: The foam beneath the concrete expands, lifting the slab.

The polyurethane foam used in polyjacking is inorganic which is why it does not decompose or dissolve as time passes. The polyjacking technique provides a dependable and useful repair solution for sinking concrete.

The Benefits of Polyjacking​

Quick Action

15 minutes after injecting the foam, you can walk over the concrete slab without a problem. The slab is solid and stable enough to accommodate vehicular traffic as well.

Minimally invasive

The process is minimally invasive for property owners as it does not involve any major construction or digging.

Lightweight

The foam is made up of lightweight polyurethane. In comparison to materials used in other procedures such as mudjacking, polyurethane foam is a better solution.

Eco-friendly

Polyurethane foam does not let any dangerous substances seep into the ground and successfully fills in the voids in the soil.

Pocket-friendly

Owners can save up to 50% of the traditional concrete slab replacement expenses if they choose concrete leveling using polyjacking.

Waterproof

Polyurethane foam is waterproof and not easily weakened by exposure to water.
