"Groundworksâ listened to our input and throughly evaluated the requirements to support the basement walls and prevent water from coming in. They were on time and communicated clearly and timely. The Foreman did an evaluation and recommended a couple changes to the plan that I agreed with and weâ re beneficial. The 3 workers knew what they were doing and worked hard. I appreciate the manner they communicated and they were very friendly. Overall, they did a great job!"

"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."

"As a project manager in the construction industry I can tend to be a little overbearing when it comes to hiring contractors to work on my own home. During the discovery/bid process Cody was extremely knowledgeable and helpful with explaining the issue and the options we had to remedy my problem. Their bid came in at a fair value and below what I was as expecting so we signed the contract to move forward with the work. Olshan installed 8 cable lock st piers to lift and stabilize our foundation. Alejandro was in charge of the actual work on our home and he is an absolute rock star. He was extremely knowledgeable and went above and beyond to ensure that the job was performed correctly. His crew was respectful of our home and got in and out as quickly and cleanly as they could. Alejandro answered all texts and phone calls in a reasonable amount of time and always kept me in the loop. Overall, foundation work is tough but Olshan made it look easy. Cody and Alejandro were exceptional throughout the process and I trust if I ever need anything in the future they will be there for me."

Basement Waterproofing FAQs, answered by experts

Topical sealers adhere to the surface of concrete to create a protective layer. In many cases, this is all you need for concrete that sees light to moderate traffic, such as your basement. Penetrating sealers, on the other hand, bond with the free lime in the top layer of concrete to form calcium silicate, which prevents liquid from passing through. This type of sealer protects the surface from water, oil, and gasoline spills.

The purpose of crawl space encapsulation is to prevent mold by blocking moisture and reducing humidity. If the vapor barrier is properly installed, it significantly reduces the chance of mold developing within the crawl space. However, mold can sometimes grow behind the encapsulation material, but it will be sealed away from the main area. Additionally, moisture can still condense inside the encapsulated space, so if you notice excess humidity, installing a dehumidifier is recommended to prevent mold and mildew growth.

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that—like installing air fresheners and a dehumidifier—can help keep musty odors from returning.

While water in your basement is unlikely to make you sick unless it’s coming from a sewage backup, mold is likely to start to grow in wet areas within 24 hours, and mold can make you sick. According to the Centers for Disease Control and Prevention (CDC), inhaling mold spores can cause allergy symptoms, including runny nose, itchy eyes, difficulty breathing, wheezing, and itchy skin. Individuals with pre-existing respiratory issues like asthma and immunocompromised individuals are at an elevated risk of symptoms when inhaling mold spores.
