Old neighborhoods, old walks
About 27.5% of homes in St. Joseph were built in 1939 or earlier, and the median home here dates to 1962. Many of the front walks are as old as the house. Decades of tree roots, freeze-thaw heave, and loess settlement leave a run of panels that steps up and down like a staircase.
Because the panels are thin and the voids under them are wide, sidewalks are usually a clean foam job. The lift is precise, the ports are small, and the walk is usable the same day.
