Our Services

Foundation Repair
Do you know how well your home is standing up to the test of time? Is it strong and sturdy or does it feel like it’s on shaky ground? Whether you interpret this figuratively or literally, it’s so important for your home to have a strong foundation.

Crawl Space Repair & Encapsulation
Normally these areas are empty, but you never know what creepy conditions you’ll find there – mold, pest infestation, wet insulation, and much more.

Basement Waterproofing
Water is essential, but other than coming out of faucets for specific needs, you do not want water in your house. This powerful element and force of nature can wreak havoc on your home.

Structural Wall Repair
Repair your failing and crumbling structural walls with our proven products.

Ricky came today and was amazing! Joked with us and made me feel comfortable with him being there. My Grandchildren were laughing, as myself was, at every joke he made. Couldn't have asked for a more better tech man! Was absolutely very thorough, and explained everything in detail, when I had a question. Highly recommend.

This review goes out to our Inspector – Kevin from Groundwork’s in the Twin Cities. My wife and I have a garage floor that is cracked and had sunk a bit, so we reached out to Groundwork’s and a couple of other local firms to assess and quote the needed repairs. Kevin appeared right on time and talked us through the Groundwork’s assessment process. For the next 30 minutes or so, Kevin setup their equipment and analyzed the root cause of the crack and suggestions for repair. We then gathered again to discuss what he found, why the crack occurred, solutions for both the short term and long term, and pricing for each option. This wasn’t a high pressured sales call, this was a team that came prepared to diagnose the problem and present solutions! While it’s too cold to make the repairs in the middle of a MN Winter, we’ll be calling on Kevin come Spring! Well done Groundworks!

Our technician Michael did a great job explaining our options on fixing our front sidewalk. He was informative and thorough and was not pushy. We have worked with groundwork’s in the past and look forward to working with them again. Thanks Michael.

On the day of our estimation appointment, Nathan Brand contacted us to confirm the appointment and arrived promptly at the scheduled time. He was very professional, friendly, and knowledgeable. He first explained the estimation process and then invested a considerable amount of time investigating and determining a solution for our foundation issues. He then patiently and thoroughly explained the repair estimation. We ultimately decided not to proceed with the foundation repair at this time but are grateful for the time Nathan invested for our estimation.

We called Innovative Basement Authority to come and give us a quote for repairing some concerns we were having with our foundation. Jan Kottke came to our home and conducted a very thorough inspection of our foundation. He explained to us that the areas that we had concerns over were not a significant threat to the integrity of our home and that we did not need any repairs at this time. Jan then took the time to educate me as to what I should watch for to maintain our foundation and know when to call them back should the need arise. I highly recommend this company to anyone who has issues with their home or even concerned about possible issues they may have. They will address your issues and give you honest answers.
