In Highland Park, Illinois, concrete slabs, patios, driveways, or sidewalks are lifted and leveled using a technique called polyjacking. Polyjacking is done by using expanding and lightweight polyurethane foam. It is a quicker and more reliable, non-toxic alternative to mudjacking for leveling concrete.

Why Does Concrete Settle?

Several components such as inadequate compaction, poor drainage, inappropriate site conditions, and tree roots, can cause concrete to settle. Rain and gutter water eroding debris from your driveway or sidewalk is the most common cause of the concrete sinking. Because of cavities or pockets that form beneath it, your concrete can shift over time.

Another element is the existence of clay-rich soil, which changes in size in response to moisture levels. This soil expands when it is wet and shrinks when it is dry. The change in moisture content renders the ground unstable, which causes the concrete to move and sink.

Why Does Concrete Settle

Concrete Leveling Using Polyjacking

The soil must be strong and durable for slab replacement. If that does not happen, it might be unable to carry the weight of the concrete. The slab can only be replaced if the soil is stable.

Benefits of Polyjacking​

Fast Acting

A short 15 minutes after the foam injection, you can easily walk on the concrete slab. The slab is strong enough to accommodate vehicular traffic as well.

Minimally-Invasive

The process causes minimal invasion for homeowners as it does not involve any major construction or digging.

Lightweight

Polyurethane foam is made of very lightweight material compared to other methods of leveling, such as mudjacking, that use heavy materials and cause soil settlement.

Environmentally Friendly

Polyurethane foam shows no reaction to moisture. It does not let any harmful chemical substances seep into the ground.

Cost-Effective

Owners can easily save almost 50% of the traditional concrete slab replacement expenses if they go for concrete leveling by polyjacking.

Waterproof

Polyurethane foam is not affected by water once it's been settled. It is waterproof and durable.
