PolyLevel™ Concrete Leveling & Lifting

The sunken and cracked concrete around your Mercer home is both an eyesore and a safety hazard. It is also likely to get worse, but we can fix it for you.

Our experts use PolyLevel, a superior polyurethane foam. Small holes are drilled in the concrete, the foam is injected and the expanding foam lifts the concrete. The majority of contractors you will call use mudjacking instead of foam. Mudjacking is heavier, require larger holes in the concrete and does not last as long as PolyLevel. Call us today to learn more.

SuperSump Safeguards Basement in Aledo, IL

Mark B. is the homeowner of this basement in Aledo was concerned about water coming into his basement whenever it would rain. Mark was especially worried because the basement was somewhat finished so he wasn't sure what area to expose to find the source of the seepage so he called the experts at MidAmerica Basement Systems.

The team installed the SuperSump system which is a patented system that can be fitted with the cast iron zoeller pump the space would need. The SuperSump comes with an airtight lid and airtight drain which allow water to drain but does not allow water vapor to rise back into the space. The lid also prevents debris from falling into the sump jeopardizing the function of the sump. WaterWatch also comes with the SuperSump to alert Mark of issues that may arise.

The team constructed a discharge line and connected it to the LawnScape to expel water out of the space. The team also installed the IceGuard which will repel water away from the foundation walls in the case of a pipe freezing. Now Mark has fewer worries when he sees a cloud in the sky!

Stabilizing and Waterproofing Basement in Alexis, IL

Bill was noticing a slight shift in his block foundation that was allowing water to seep in through the walls. He contacted MidAmerica Basement Systems to have his issue resolved. The shifting that had appeared was due to a bowing wall issue, which was then leading to the seeping water. It was suggested that a PowerBrace system be installed to address the bowing wall. PowerBraces are an I-Beam system that allows for the beams to be tightened, permanently stabilizing the wall and potentially straightening it. To address the leaking wall, CleanSpace Liner was placed along the wall, and WaterGuard was installed around the perimeter of the basement. Both systems work together to keep water from surfacing, and redirecting it to the TripleSafe sump. There, water will properly be discharged from the home, leaving Bill’s basement stable and dry once again.
