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.

LJ, Anthony, Kevin and Mike were amazing,! We didn't realize how poorly the basement had been left behind the plywood walls until this crew came to get it sorted. They weren't phased by anything, that level of confidence in a crew was so reassuring for us during this project. The work was done quickly and so thoroughly!

Nathan Brand was our basement inspector, and we were extremely satisfied with his level of expertise, his thorough inspection and analysis of our basement, and the amount of time that he spent with us educating us on the process. He told us straight up that he wasn’t going to leave for the day until we had all of our questions answered and we were completely satisfied that we had the information we needed in order to make a decision. Nathan was very relatable and personable, and it was obvious that he truly cares about helping people through this process.

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!
