Concrete leveling in Sioux City
Concrete help across Iowa's fourth-largest city, from bluff-top streets to the river flats.
Sioux City is the seat of Woodbury County and reaches into Plymouth County, with 85,797 residents at the 2020 census. It grew up where the Big Sioux River meets the Missouri, and its neighborhoods, including Morningside, the Northside, the Heights, Rose Hill, Riverside, the West Side and Southern Hills, spread across bluffs and valleys at the north end of the Loess Hills.
Hills, loess and runoff
The Iowa Geological Survey describes Loess Hills soils as cohesive when dry but prone to collapse when wet, with high erosion rates. On Sioux City's hillside streets, that shows up as washed-out edges under driveways and walks, steps that drop as soil erodes beside them, and slabs that sink where downspouts empty.
The sidewalk zones
The city inspects one of ten zones each year. If your panels have white paint, you can hire a licensed, bonded and city-registered contractor with a permit, or let the city's contractor handle it. See sidewalk repair.
