Concrete leveling helps to raise and level concrete slabs, sidewalks, patios, and driveways. This process involves polyjacking, a method in which polyurethane foam is used. It is a non-toxic, quick, and long-lasting process when compared to other concrete leveling solutions.

Why Does Concrete Settle?

Concrete can settle due to plenty of reasons such as lack of proper drainage, poor compaction, tree roots, as well as bad site conditions. The primary cause for concrete settlement is rainwater or gutter water washing out debris from underneath driveways and sidewalks. The voids or pockets created consequently can lead concrete to settle.

Another major cause of concrete settlement is the contraction and expansion of clay-rich soil due to changing moisture content. Consequently, the ground becomes unstable, causing the concrete to shift and sink even more.

Why Does Concrete Settle

Concrete Leveling Using Polyjacking

The soil beneath the concrete surfaces should be strong enough to hold its weight. Otherwise, it will be unable to support the weight of the concrete, making it impossible to replace the slab.

Benefits of Polyjacking​

Fast Acting

Just 15 minutes after the foam is injected, you will easily be able to walk over the concrete. It will even be enough to accommodate vehicular traffic.


Polyjacking causes minimum invasion as it does not involve any major excavation or digging.


The foam consists of lightweight polyurethane which is easy to use. Contrary to other leveling techniques like mudjacking that use heavy materials.

Environmentally Friendly

The foam used for polyjacking is not easily affected by moisture and does not leak which prevents dangerous substances from seeping into the ground.


Owners can easily save up to half of the regular concrete slab replacement costs if they go for concrete leveling by polyjacking.


Polyurethane foam is not damaged by water once it is settled. It is waterproof and long-lasting.
