Basement Waterproofing in Sioux City
Sioux City lies inside Woodbury County in Iowa. Census figures put the town at about 85,469 residents and 32,449 households. 65 percent of occupied homes are owner occupied, and 24,435 of them are detached single family houses.
Work here is served from the Norfolk office, about 80 minutes away at 62 miles. Across Woodbury County as a whole there are 31,632 detached single family homes, and 68 percent of occupied housing is owner occupied. Those households are roughly 75 percent of the Woodbury County total. Woodbury County holds about 105,760 people and 43,121 housing units in total. Half the housing predates 1955, and the years before 1940 were the busiest building years at 10,913 homes. A median home value of $149,800 and a median household income of $64,250 is what the American Community Survey records. 21,227 of those homes are lived in by their owners and 11,222 are rented. Roughly 86 percent of the housing here, 27,823 homes, went up before 1980, when footing drains and grade separations were not what they are now.

What we fix
The USDA survey under Sioux City reads silt and rates its shrink swell potential moderate. Soil that changes volume against a wall through the year is the driver behind most of what we are called out to look at.
What this looks likeFrost reaches 36 to 42 inches here and the ground cycles through freeze and thaw 60 to 80 times in a normal year, which is what lifts and drops a slab under the 24,435 detached houses in Sioux City.
What this looks likeOf the housing here, 27,823 homes predate 1980, with the biggest block of it going up before 1940. Original drainage is usually the story on those.
What this looks likeSioux City conditions
Soil mapping within Sioux City returns Ida at about 40 percent of the survey, with Onawa and Hamburg alongside it. By texture that survey runs 30 percent clay and 40 percent silt. The weighted linear extensibility figure, which is how much the soil changes volume between wet and dry, sits at 4.06 percent, a moderate shrink swell rating. The sample inside the city runs 20 percent clay against 30 percent across Woodbury County, so the ground here is lighter than the county average.
Ground here freezes to 36 to 42 inches and cycles through freeze and thaw 60 to 80 times a year. With 35 to 40 inches a year of rain and snow, the ground beside a footing is wet in spring and dry by August.
The years before 1940 put up more homes than any other decade, 10,913 of them, and the median year built is 1955. 27,823 of those homes predate 1980, which is where we most often find footing drains that were never installed and backfill that was never compacted. 16 percent of the housing here, 5,285 units, sits in buildings of five or more, so a fair share of local work is on shared structures rather than single family homes. 62 percent of owner occupied homes here carry a mortgage, which is usually why a lender or an appraiser is the first to ask about a crack.

"A vapor barrier without drainage on a wet wall is the most expensive mold lab you'll ever pay for. I've cut into walls fifteen months after bare poly went up on weeping block, and what you find behind that poly is a science experiment. We don't do it. If the wall needs drainage first, we install drainage first."
