PolyLevel Lifts Concrete Patio in Chesterfield

Sinking concrete slabs can cause potential tripping hazards. Walt and Virginia M. were worried about the patio at their rental property becoming unsafe for their tenants so they called Woods Basement Systems. Woods recommended injecting PolyLevel under the concrete slabs of the patio.


PolyLevel is an expanding polymer foam that was injected under the patio. It lifts and levels the concrete and then hardens so the concrete is usable within 15 minutes. It's also waterproof so it won't wash away.

Sinking and Uneven Driveway Repaired in Saint Louis, MO

A concrete driveway was settling in Saint Louis, MO, causing the slabs to sink and become uneven. To solve this issue, the PolyLevel System was installed. This will stabilize, lift, and level the concrete slabs with high-strength polyurethane foam. Pea-sized holes were drilled into the concrete and the foam was injected to fill the void underneath. This installation technique allows the foam to expand as it cures, precisely lifting the slab back up. Additionally, NexusPro Joint Sealant was installed. This will seal the joints and cracks in the concrete. It will provide long-lasting flexibility and stand up to harsh weather conditions. These systems will improve the safety of the driveway and restore peace of mind for years to come!

Leveling A Driveway In Saint Louis, MO

As it sets, the foam lifts the concrete back up to its original position. With this system installed, this driveway will remain level for years to come.
