Before & After Photos

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.

Frank of Affton, Missouri had uneven concrete slabs on his front sidewalk which can be a tripping hazard, so he called Woods Basement Systems for a solution. Systems design specialist, Peter N. recommended PolyLevel for the job.

Foreman, Andrew T. installed the PolyLevel. PolyLevel is a high density polyurethane formula which is used to permanently lift and stabilize sinking concrete slabs. Small, dime-sized holes are drilled into the concrete and then the polymer is injected into the void. The holes are covered with cement and within 15 minutes to concrete can be used again so there is no long wait for it to settle. 

Now Frank M. can safely use his sidewalk. 

A sidewalk in St. Louis, MO was settling, causing a large crack to form. Woods repaired this concrete by first injecting PolyLevel into the slabs, bringing them back up to their original position. NexusPro was also added to seal up the crack, so it doesn't grow. This concrete will stay stable and even for years to come!
