Basement waterproofing & foundation repair in Council Bluffs
Council Bluffs sits where the Loess Hills meet the Missouri River bottoms. That geography shapes why basements here get wet and why foundations move. This guide explains the common causes and fixes in plain language. When you're ready, we can pass your request to a participating local contractor.
Why basements in Council Bluffs take on water
Two very different soils
Pottawattamie County's soil associations split into river-bottom alluvial soils in the west, which the county notes have flooding and wetness limitations, and deep, silty loess soils (such as Monona and Ida) on the bluffs and uplands.1,2 Low-lying homes deal more with groundwater. Hillside homes deal more with surface runoff and erosion.
A river-protected city
About 28 miles of levees surround Council Bluffs. The city says they protect about 11,700 homes and 35,000 residents, and that without them roughly 60% of the city would face greater flood risk.3 Levees hold back the river, but they don't stop rain, snowmelt, or groundwater from reaching your foundation.
Long high-water seasons
In 2011, Missouri River levels stayed above the 100-year flood elevation for about 90 days, according to the U.S. Army Corps of Engineers.4 The city lists major floods in 1952, 1967, 1984, 1993, 1997, 2011, 2019, and 2024.3

Check your own property first (free)
- Look up your address on the FEMA Flood Map Service Center. Many levee-protected areas are shown with reduced, not zero, flood risk.
- Look up your lot's soil type on the NRCS Web Soil Survey.
- Walk outside after a rain. Check whether downspouts empty within a few feet of the wall and whether the ground slopes toward the house.
