"Everything went as explained, diagramed, and promised by our System Design Specialist, Mr. Nicolas Hruska. We initially contacted just the top two Foundation Repair Experts listed on Angie's List because we can't afford to have our home repaired by anyone who lacks the proper credentials, staff, tools, training, techniques, supplies, 25 year transferrable warranty, and the hands on experience to deliver all services as promised. We are extremely pleased with the final results to take back our homes basement from poor workmanship done by the original builder and owner of our home back in 1979 We purchased the home in 2001 and unknown to us the foundation had been placed on top of clay based sub-soil which was an acceptable building practice back in 1979. Today's building codes prohibit this careless and costly practice of home site preparation for the homeowner. A word to the wise, do your home work first and then protect the biggest asset that most Americans have, their home. Respectfully, Kenny L. Hutcheson, CMSgt, USAF/USN, Ret. Indianola, Iowa"

MidAmerica Basement Systems is your premier locally owned and operated company that specializes in foundation repair, basement waterproofing, crawl space repair, concrete leveling, and radon mitigation.

"Salesman that we were to replace dry wall. Later learned we were to have it removed. Attempts to reach supervisors and owners resulted in zero until time to do installation. Gave $1300+ down. Note: this went to the salesman, not to MABS. Then salesman stated $12,000 more if MABS removed the dry wall. Paid salesman and his friend to remove it but didn't do all of it! Sent certified letters to Cedar Rapids address after we got no verbal responses to phone calls. Later learned they receive no mail there, only in Davenport. Were to have GFI outlet placed at far end of basement. 3 electricians said not possible. Also discharge was to be underground to rear of yard which we thought meant to back! House sits on clay. Was to discharge under ground out 10 feet from house. Canceled installation and have found that other basement waterproofing companies do not require 2.5 feet of dry wall removed: only baseboard. Cost was same as MABS. Now we must pay to have drywall installed after the waterproofing is completed."

Basement Waterproofing questions, answered by experts

Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.

Depending on the severity, a slab leak can go undetected for months or even years, especially if you don’t carry out routine foundation inspections to find foundation leaks early. However, minor leaks are likely to turn into more severe leaks over time, so you might notice increases in water bills and issues with yard drainage, even if the problem is minor.

While it’s possible to seal a foundation yourself, it’s not recommended, as it’s a tricky and labor-intensive job. Foundation sealing is best left to the pros to save yourself time, remove the risk of doing it wrong, and keeping yourself safe. Call a foundation repair professional near you to see what the job will cost.

There are a few downsides to a wet room, the most important of which is the risk of mold growth from the moisture and humidity. Standard bathrooms can have the same issue, but wet rooms are more likely to experience problems because water is less carefully contained. You also have less privacy since the entire bathroom is open, and the room must include waterproofing, which makes wet rooms more expensive to install than regular bathrooms.

Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it’s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques—like soil gradation and gutter and leader installation—to resolve the underlying problem.
