"We’ve had a lot of crews in our home for various projects over the years, and I have to say this was one of the most courteous. They worked hard, navigating through our kitchen to access the basement and I really appreciated their efforts. Thank you MTU, we now have safe walls in our cellar and fresh beams to keep the house standing ;)"

"The workers were hard working. Did a great job. The only concern we had was the lack of attention to the workers: no porta potty and no machinery to help carry the heavy concrete. Still waiting for the $250 gift card reward, lol!"

"I had purchased $200 worth of services for $119 on Angie's list because we had a leaking drain in our shower. The plumber came out and went under the house twice, without being sure what the problem was. We (the plumber and me) determined that when you stand in the shower it leaked. He said the problem was the mortar under the shower and it would cost approximately $650 to fix. Two weeks later I started looking on Angie's again and reading reviews. After much reading, I called Jerry. I explained the situation to him on the phone and he asked if I had a tile floor in the shower. I don't, I have a one-piece fiberglass shower. He then told me I wouldn't have mortar under the shower and he could fix it for $100. This conversation happened on Monday. I scheduled him for Friday. Well this is Friday and Jerry was here approximately 30 minutes and charged me $100. The drain had broken off from the pipe, all he had to do was move it and he could tell. What a great guy!!!! Honest and efficient. It is great, what a relief. I have a plumber that I trust for life. Yippeeee!!

"Immediate call back when requested quote, and great service. Crew workers are hard working and respectful. The work performed went way beyond the basics... from cutting down 3 ft weeds, removing debris, spraying for weed control, trimming under bushes, cleaning up edges of flower bed, and then spreading bark. I would hire them again, and recommend this company ?."

Basement Waterproofing FAQs, answered by experts

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

To ensure your basement walls are waterproof, it's crucial to address any existing moisture issues before finishing. Inspect for signs of water seepage, such as dampness or discoloration, and repair any leaks or cracks. Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.

Proper drainage systems, such as interior or exterior waterproofing, can also be beneficial.

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.

Crawl spaces are the more desirable option overall because they provide additional space for storage and utilities, but they are more expensive to install and maintain. Slab foundations are considered a better option in warmer climates where the depth of the frost line isn’t an issue because they’re more affordable, but crawl spaces are better in areas where the frost line is deep or where flooding can be an issue.

The most expensive foundation repair method is to install helical piers. Helical piers are a type of steel pier used to support sinking foundations in areas with poor soil conditions or deep bedrock. This foundation repair method can cost up to $3,000 per pier, including labor, because of its material and labor-intensive installation process. Total foundation repair costs can easily reach over $20,000 using this method.
