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.
