Aaron was excited that he had just purchased his first home, but quickly became aware of all the issues that arise being a homeowner. He found out that his main entertainment room had a bad water issue and ruined half the room. Aaron made the call to MidAmerica Basement Systems to deal with the water issue. What he surprisingly found out, is that we also do basement remodels as well. Aaron was set up with WaterGurad, SuperSump, and UltraSump systems, and also got his basement looking like new again with EverLast Wall Panels.

Steve and JoAnn were having issues with entering their home. The concrete step had sunken, leaving a larger step into their house. The dropped concrete step had caused a 3-inch difference between the doorway and top step. Design specialist, Cole had offered the solution of PolyLevel to lift and stabilize the step, preventing the homeowners from having to replace the entire area. The PolyLevel was injected into the stairs, filled the voids, and lifted them to their original position. The once 3-inch difference has now been fixed, making the entrance to their home smoother.

Basement Finishing & Remodeling in DeWitt, IA

Waterproofing your basement prevents outside water from coming in but what if a pipe bursts or the water heater leaks inside the home. A newly finished basement done by your average contractor will mold and rot if there is an internal leak. You'll have to tear out your new basement! We fix this issue.

Our Products Include :
  • Waterproof, washable, insulated walls           
  • Mold-Resistant, No-Sag suspended ceiling
  • Modular carpet, tile & faux wood flooring

  • Energy-efficient, double-paned basement windows
  • Attractive Sunhouse basement window wells
  • French, bifold, louvre & six-paneled steel doors
Unlike the average DeWitt contractor we use completely inorganic, waterproof materials. Even if the basement floods your walls and floors will not be damaged by the water. These waterproof products are patented and are built to create an attractive finished basement that lasts a lifetime.

PolyLevel™ Concrete Leveling & Lifting

The sunken and cracked concrete around your DeWitt 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.

We Fix
  • Cracked Driveways
  • Uneven Patios
  • Sinking Sidewalks      

  • Uneven Concrete
  • Sunken Pool Decks
  • Highway & Commercial Issues

Homeowners Michael and Bobbi have lived in their 1970’s home for the last 15 years. They recently had work done to their home to fix a bowing wall. MidAmerica Basement System thinks it is very important to have annual maintenance done on the system that we install to ensure their lifespan and quality.

Cracked and Sunken Concrete is Injected with PolyLevel in De Witt, IA

Over time, the soil underneath concrete becomes compressed, creating voids. When voids become present, the concrete begins to sink, and can crack underneath excess stress. This produces the area to become unsafe and hazardous to access. Injecting PolyLevel from MidAmerica Basement Systems allows for the concrete to become stable and level again. PolyLevel offers a permanent solution to filling voids, leveling concrete, and reducing hazardous areas. The lightweight material also offers less stress on the compressed soil, preventing future compression.

I have a leaky basement. The previous owners had already finished it. It does have a sump pump. The leaks look as if it's just cracks in the walls. We don't get a lot of water but just enough to be annoying and to not allow us to put any type of flooring down.i am just wondering what the most reasonable thing is to do? Thanks for your time
