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.

Michael Bowers from Groundworks really took his time and explained everything he saw during his walk through on my home. I had a warranty issue and along with taking care of that I had two others spots that needed attention and will be getting them fixed in the Spring. I highly recommend Groundworks for any and all concrete issues around your home!

Jake came over to do the inspection and was very thorough and professional. He explained what the problems were and gave us three levels of corrective measures. There was absolute no pressure on which to chose. We were very confident his choices.Hunter and Paul came to do the work. He told us what the project would entail and kept us up to date each step of the way. He and Paul were very professional and patient as we asked questions. We had one question Regarding mold and discussed it with Hunter and Jake. Jake said he would be in Grand Forks for an inspection and would come over and take a look. He and Hunter agreed on what they could do.Hunter and Paul worked so hard. When they were done he walked us though everything they had done and why. They were great.

Drain Tile and Sump Pump installation. From start to finish the service was excellent. David inspected our house, discussed what was needed, walked us through the estimate. David was consistently available for questions prior to the installation. Austin F., Dakota M. And Billy B. Were the installers. They were on time and communicated everything they were doing. They were polite, approachable, and clearly knowledgeable about the process. The installation looks great and the site was completely clean when they were done. I would highly recommend Groundwork’s and these staff for any work you need.

We had our garage floor leveled and cracks filled and a basement wall waterproofed (gutter system with pump and wall seal) in Minneapolis in 2024. Both projects were done by people who take pride in their work and strive for the best outcome. Our garage floor was in sad shape, and Andrew spent extra time to get it as level as could be and filled the many cracks thoroughly. One side of the garage went up 4 inches to make it level again. As for our basement, Jeremiah T, Dion R, and Jaden R did a great job installing the gutter system under the floor with the pump, drainage, and wall seal membrane that went with it.
