Basement Finishing & Remodeling in Knoxville, IL

Waterproofing your basement prevents outside water from coming in but what if a pipe bursts or the water heater leaks inside the home.

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 Knoxville 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.

Leaking Basement Installs Waterproofing System in Knoxville, IL

Emily was concerned about her basement. During heavy rains portions of the basement would leak, leaving the finished portion at risk of damage. She reached out to MidAmerica Basement Systems to have her basement waterproofed and to protect the finished area. WaterGuard drainage track was installed around the perimeter of the basement to collect any seeping water and redirect it to a TripleSafe. The TripleSafe includes a battery backup sump that ensure the basement will not flood during power outages. Now Emily has a dry basement that won’t damage her finished portion.

Emily had a finished basement but was concerned with the area. Every so often during heavy rains, small amounts of water would leak into her basement, posing threat to the finished area. She reached out to MidAmerica Basement Systems to have the problem fixed for good. She was offered a full perimeter waterproof system with WaterGuard and a TripleSafe systems. After portions of the finished walls were removed, WaterGuard was installed around the perimeter of the basement to collect seeping water, and redirect it to the TripleSafe. The TripleSafe then successfully discharges the water out of the basement to keep it dry and eliminate the moisture threat to Emily’s finished basement.

Seeping Water Stopped in Knoxville, IL

Dan Garner, a certified design specialist, met with Steve. Dan investigated the property thoroughly and gave Steve a written estimate after the investigation. Dan recommended a full perimeter WaterGuard System, a TripleSafe Sump Pump, along with a SuperSump Sump Pump with buried discharge lines, and the IceGuard attachment pieces.

Waterproofed Basement in Knoxville, IL

Homeowner Fred D. of Knoxville, IL had some issues with his basement. Water was coming in through his basement floors. He knew he had to get something done, so Fred contacted MidAmerica Basement Systems. After meeting with design specialist Dan Garner, Fred was ready to waterproof his basement.

In Fred's basement, many patented waterproofing projects have been installed. The patented sub-floor drainage system, WaterGuard, keeps water out by encompassing the perimeter. CleanSpace keeps the walls protected, and the SuperSump sump pump pumps any water out before it affects the interior. Additionally, a drainage line is installed to keep the water out of the space, and away from the foundation.

Water proof basement
Vicinity of E. Mill St. in Knoxville
I have a basement that continues to get water. It is cinder block walls and in certain areas there is a white powdery like substance on the walls. I had a sump pump installed but in heavy rains it can't handle the amount of water that comes in. I hope you can help.
Vicinity of S. Market St. in Knoxville
I have an old home, moved in last summer. The home did not have a single gutter on it when I moved in, but I have managed to put most of them up since moving in but I cannot get the upper levels. The foundation is old and in need of repair in several spots. With all of this rain, the water leaks in like a sieve. It's not a finished basement, but the water leakage is getting worse as the ground is getting more saturated. I would like an estimate to waterproof two main walls. Thanks
Vicinity of Broad Avenue in Knoxville
My husband and I would like a quote a two different projects. First we would like to totally waterproof our basement so we can finish it off and add a bedroom or two down there. We currently have a little channel that runs along the inside walls of the basement to channel the water to our sump pump which works wonderful but we want something that isn't visible. The channel does an awesome job except for on the west side of our basement where the sump pump is located. We have taken on water there. Secondly, we would like a quote on installing an egress window. We currently have small basement windows but with us wanting to put a bedroom down there, we want an egress window. We would like to start these projects sooner than later. Please give me or my husband a call. Thanks. Kendra Kenny

Leaking walls, flooding basement
Vicinity of W Sunnyview in Knoxville
We have water coming in from outside in the rear of the house due to a gap between the patio and the house (we think). It doesn't drain correctly because the drain is frequently clogged with tree roots and the water comes in on the opposite side of the house from the sump pump.
Vicinity of Stony Hollow Rd. in Knoxville
My house was built with a cinder blocked basement in 1995. The basement was finished off with drywall and carpet and has now began to drastically leak in the Northwest corner. I've removed the drywall to see the problem. During heavy rains, the water pours down the interior wall in this area.
Vicinity of E. Mill St. in Knoxville
Brick basement/foundation. Bowed in, possibly because of oak tree outside. Some leaking, mortar gone in some places. Need estimate and proof of insurance.
Vicinity of Northview Dr in Knoxville
We get water running in the basement when it rains more than a couple of inches. It leaks on the north wall and sometimes on the east wall. We live in a split-level house and the basement is only 4 feet in the ground. The house was built in the early 70's. The basement is about 35 feet by 25 feet.
