What puts water in a Harrisonburg basement
The ground under Harrisonburg holds water close to the surface: in a typical year the seasonal-high water table modeled from USDA soil survey rises to within about 2.5 ft of grade, shallower than the roughly 7 ft depth of a full basement floor. Where groundwater stands above the floor it presses on the slab and the wall-floor joint, the hydrostatic pressure that drives water through basement concrete.
Roughly 86 freeze-thaw cycles a year (ERA5) add frost pressure against the wall on top of that.
