Before After
Concrete Porch Step Repaired in Knapp, WI Concrete Porch Step Repaired in Knapp, WI

David T. of Knapp, WI had a gap between his porch step and his house, and he wanted the concrete repaired rather than replaced. He came across our website online and browsed through our concrete repair products. He called our office line and set up a FREE Estimate with our Design Specialist, Pedro Guevara. Pedro went to his home, inspected the concrete, and came up with a solution of our PolyLevel polyurethane foam. David got all of his questions answered and was confident with the solution, so they went ahead with the project. 

Our Foreman, Sam Klennert, and his crew member injected 349 pounds of our PolyLevel beneath the concrete to fill the gaps caused by soil erosion and to raise and stabilize the surface. Our PolyLevel is noninvasive, it cures quick so it can be used within 15 minutes after the foam is injected, and it is waterproof. David was happy with the project and loves the new view of his porch!

Radon is an odorless, invisible gas that can lead to lung cancer and other negative health outcomes for you and your family. Unfortunately, because it is invisible, it is impossible to detect without the help of a professional. That’s where American Waterworks comes in. We offer efficient, highly accurate radon tests to help you determine whether you require a radon mitigation system. After that, if needed, our professionals can require a highly effective radon mitigation system to keep you and your family healthy.

Job Stories From Knapp, WI
Sump Pump Installed in Knapp, WI

Rupert and Doris S. of Knapp, WI had water leaking from their pre-existing sump pump causing him to worry about water moisture problems. They did some research online and came across our American Waterworks website. They called our main office line and scheduled a FREE Estimate with our Design Specialist, Chad Johnson. Chad went to his home to inspect the sump pump and help figure out a solution that fit their needs. Rupert and Doris were comfortable with Chad's proposal of our SuperSump sump pump, so they went ahead with the project. 

Our Foreman, Arturo Mares, and his production team started the project by cutting out the concrete around their pre-existing sump pump. Our crew replaced their sump pump with our SuperSump sump pump, which is made to keep basements clean and dry for long periods of time. To complete the project, Arturo and his team replaced the concrete and made sure Rupert and Doris were satisfied with the project!
