Before & After Photos

A homeowner in Cedar Rapids, Iowa, faced a tilted front sidewalk that was actively directing surface water runoff straight beneath their porch deck, putting both the porch structure and home foundation at risk of severe water damage. Left unchecked, the pooling water threatened to wash away the supporting subgrade soil and compromise the long-term structural integrity of the home.

To eliminate the hazard without invasive concrete demolition, System Design Specialist Tim Rollet evaluated the site and designed a targeted repair strategy using PolyLevel® Concrete Leveling through MidAmerica Basement Systems.

Foreman Justin Maddox and crew member Devin S. executed the restoration with precision. The team strategically drilled pea-sized injection ports through the tilted sidewalk slabs and injected high-strength PolyLevel polyurethane foam into the underlying subbase. As the geopolymer expanded, it filled subterranean voids, compacted loose supporting soil, and lifted the sunken concrete back to a stable, level plane, properly redirecting water flow away from the porch and foundation. The crew patched the injection holes, leaving behind a safe, fully stabilized sidewalk engineered to protect the property for years to come.

Polyfoam used to fix unsafe driveway. 

In Iowa City, IA, one of our recent projects involved repairing a driveway and sidewalk for easier access. Before our intervention, the uneven concrete made it challenging for one of the residents who relies on a wheelchair. We utilized PolyLevel to expertly lift and stabilize the concrete, ensuring a smooth surface. The after photo showcases how we restored safety and functionality to this area. We also applied NexusPro Joint Sealant to seal all cracks, providing lasting protection from water damage and preventing future sinking. At MidAmerica Basement Systems, your accessibility needs come first and we are happy to have successfully helped this Iowa City homeowner with their concrete repair needs. 

This whole sidewalk had cracks and settlement issues. Thanks to the PolyLevel system, the sidewalk looks almost brand new. The white spots on the concrete are drilled hole with ports in them where the foam will be injected. The foam is injected under the concrete to raise it back up to its original position.

Uneven concrete can pose safety hazards to pedestrians of all ages. With PolyLevel injections offered by MidAmerica Basement Systems, the hassle of concrete leveling is made simple. PolyLevel is a lightweight, quick-drying, solution for leveling sinking concrete. Poly ports, roughly 5/8-inch in size, allow for the polyurethane to be injected under the concrete slabs, filling the voids, and lifting and leveling them back to proper elevations. The lightweight foam offers less pressure on the ground, providing a more permanent solution over other techniques. The quick dry time of PolyLevel also allows for accessibility to the area the same day as injections.
