Groundworks Provides Professional Sioux City Foundation Repair, Basement Waterproofing, and More

Situated near the northwestern part of Iowa, Sioux City is located in both Woodbury and Plymouth counties, with the majority of the city being in Woodbury County. “Siouxland” refers to Sioux City and the surrounding areas of northwestern Iowa, northeastern Nebraska, and southeastern South Dakota and is a term of endearment amongst local residents.

Situated at the furthest upstream point of the Missouri River, Sioux City is both a travel destination as well as a peaceful area to live. With an average annual rainfall of nearly 26 inches, it is slightly below the national average. However, it’s the fact that more than 60 percent of that rain falls during the summer months when humidity levels often reach 90 percent, that’s the problem. Add in the annual 30 plus inches of snow, and it’s no wonder Sioux City homeowners deal with wet basements and crawl spaces nearly year-round.

The area’s soil differs depending on where you live in Woodbury or Plymouth County. Most soil is silt loam-based with varying levels of clay. The soil across the region also has different degrees of drainage, ranging from well-drained to poorly-drained. To sum it up, homeowners in Sioux City can experience several different types of foundation problems because the soil conditions differ considerably from area to area.

From the initial phone call to the estimate to the crew doing the work everyone was very professional and helpful. We had a drainage system put in our basement and it looks great! It only took 2 days. CJ, Sal, and John were all great to work with. Very good company.

Eric Wulf was not only helpful, he was also patient, caring and all around professional with lots of respect and tons of knowledge. He took his time explaining all there is to know about what our family needed. I would recommend Eric Wulf millions of times to people who not only wants a job well done, but with respect, patience and knowledge on all there is to know about what you need.

I needed the foundation of my house repaired due to settling from years of drought conditions. The process involved the excavation of dirt next to the basement walls, installation of 10 piers to lift and secure the foundation, replacement of a portion of the basement floor and backfilling while compacting the soil to ensure proper support for the basement walls. The crew bosses Juan and Jose were very professional and led the crew members to efficiently and effectively complete the work in 3 days. The crew members were hard workers and kept going longer than I ever could have. Any questions)concerns that I might have were always addressed in a professional manner. I would recommend Groundworks for your foundation and/or basement wall repairs.

I recently met Zak Kephart, a field inspector, while c,ompleting my consultation. My inspection was professional and assuring. Zak was very knowledgeable and explained things to my satisfaction. I have decided to use Groundworks services and will post another review once the project is completed. I can only hope that the work is as good as Zak is as an inspector.

The three employees, Emmanuel V., Luis V., and Eh T. who did the work, were friendly, polite, professional, and super diligent workers. Emmanuel even texted me pics of the work progress in the crawl space as they went along. I'm so happy with their work and with the finished product. Warren, the representative who came to my home for the estimate, was very knowledgeable and thoroughly explained what would be done, how, and why. I would definitely recommend Groundworks.

They leveled it and filled all the cracks to make it super water tight. They also checked the cracks in the drivewaythat had previous work done. They filled a sidewalk crack.We would recommend to anyone that needs this kind of work done. Josh and Jose were polite, pleasant and completely professional. Thank you Groundworks, Josh and Jose..
