St. Joseph conditions
Why foundations move in St. Joseph
What is under the ground here
Sampled inside the St. Joseph city limits, the USDA survey reads Marshall across about 80 percent of the survey. The texture split is 69 percent clay and 23 percent silt. Linear extensibility, the measure of how much a soil swells when it takes on water and shrinks when it dries, is weighted at 4.88 percent here, which USDA reads as moderate shrink swell potential. The sample inside the city runs 80 percent clay against 69 percent across Buchanan County, so the ground here is heavier than the county average.
Frost, water and the calendar
Based on NOAA 1991 to 2020 climate normals for St. Joseph Rosecrans Airport, about 6 miles away, the low reaches 32 degrees or colder on about 126 days in a normal year. Precipitation there averages 34.8 inches a year.
The housing stock
The years before 1940 put up more homes than any other decade, 9,251 of them, and the median year built is 1961. Pre 1980 construction accounts for 24,774 homes here, and that is the group where original drainage is usually the story. 16 percent of the housing here, 4,567 units, sits in buildings of five or more, so a fair share of local work is on shared structures rather than single family homes. Mortgages sit on 57 percent of the owner occupied homes in St. Joseph.

"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."
