Before & After Photos

The slabs of a concrete sidewalk were sinking in Saint Louis, MO, causing them to become uneven. To solve this issue, the PolyLevel System was first 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 concrete and restore peace of mind for years to come!

To correct uneven concrete, such as the entrance area shown in these images, our team uses a polyurethane foam injection process. This method involves injecting high-density foam beneath the affected concrete slabs, where it expands and fills voids in the underlying soil, lifting and leveling the concrete with precision. Once the concrete is properly aligned, a specialized joint sealant is applied to help prevent water intrusion, soil erosion, and cracking. This efficient repair process allows the concrete to be ready for use within 15 to 30 minutes after installation, providing a durable, long-lasting, and safe solution for concrete leveling and stabilization. 

To address cracked and uneven concrete, like the garage slab shown in these images, our team utilizes an advanced polyurethane foam lifting system. This process involves strategically injecting a high-strength foam beneath the concrete, where it expands to stabilize the soil, fill voids, and raise the slab back to a smooth, level position. After leveling is complete, a professional-grade joint sealant is applied to protect against moisture intrusion, soil washout, and future cracking. The result is a fast, effective repair that allows the concrete to be ready for use within 15 to 30 minutes, delivering a safe, long-lasting solution for concrete stabilization and repair.

A concrete driveway was sinking in Richmond Heights, MO, causing it to separate from the house. 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 slabs 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!

Marsha B. of Affton, Missouri noticed that her garage and patio were sinking and cracking due to concrete settlement. She did not want this problem to become a tripping hazard, so she called Woods Basement Systems for a solution.

Design specialist Chris T. assessed the situation and decided that PolyLevel would fix the problem. Foreman William T. then traveled to the home to get the project started. PolyLevel is inserted below the concrete through a penny-sized hole. The foam material expands and pushes the concrete back to its original position. 

Marsha B. no longer has to worry about her concrete patio or garage sinking and cracking. She now has a level patio and garage.
