"The crew was absolutely amazing! Very impressed with how professional, polite, and personable they all were. The management and crews are top notch! Management answered all the questions I had, walked me through what steps they were going to take to get things done. Dustin was extremely thorough, knowledgable, and took time to explain the recommended systems. I will 100% be utilizing them in the future strictly based on the level of trust and quality he presented! His communication was fantastic, they always arrived on time. They were careful with the property, always cleaned up when they were done. I will absolutely hire them again to complete any future foundation/basement work and I will absolutely recommend this company without reservation or hesitation. They stand behind their work."

"We did a lot of research prior to hiring Thrasher and we were not disappointed. Frankly I had been in denial (and fear) about the work I knew we needed done on our Midtown Omaha home because I was so concerned about the cost and impact on our brick Tudor. We had a crack in the brick near our garage and our basement had been leaking for a number of years with hard rains. From the start of the process, Thrasher was outstanding in terms of communication and education about what they do. Before we met with our Systems Design Specialist, Anthony, we had received e-mails and calls to confirm the date, along with a packet of educational materials about home foundations and waterproofing. When Anthony came to our home, he was very professional and performed a full inspection about our concerns. He prepared an estimate and we selected what was best for us following a thorough review of options he presented. The foundation work was completed first in ONE day. The basement waterproofing was completed the next week over a two-day time frame. The workers were very professional and arrived at the time they arranged with us. In regard to the basement waterproofing, we discovered one small issue. They came out immediately to correct this and all has been worked wonderfully since. We are very pleased with their work and commitment to customer service. Highly recommend Thrasher to anyone considering foundation or waterproofing work."

"Excellent service. Courteous and did a good job covering everything with plastic and cleaning up. They answered all of my questions and were always on time. They worked every day and did it in the time they said they would (one week). They came back after the ground dried to bury and sump pump line outside. The true test was all the rain we had this spring and my basement stayed dry!

Basement Waterproofing FAQs, answered by experts

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

No, everything doesn’t get wet if the bathroom is well-designed and the fixtures are properly installed. It’s important that the floor of a wet room drains correctly, and proper waterproofing and slip-resistant flooring are used to avoid creating slipping hazards. Since the shower isn’t housed in an enclosed space, you’ll need to make sure the towel rack and toilet paper holder are placed in areas where they won’t get wet.

If you set up a dehumidifier, it will usually dry out your wet crawl space within 12 to 24 hours. Once the space is dry, it’s a good idea to take preventative measures to keep it dry. These include installing a French drain or other exterior foundation drainage system, installing a sump pump in the crawl space, and installing a vapor barrier in addition to leaving the dehumidifier running.
