What affects the cost in Hartford
Climate: ERA5 reanalysis via Open-Meteo
USDA soil maps put Rock outcrop soils across much of Hartford, with 6 of the 14 rated sample points in slow-shedding hydrologic groups. Drainage is genuinely mixed across the city, and roughly 87 freeze-thaw cycles a year work at any crack that lets it in. Soil varies sharply across Hartford, so treat this as the pattern across 17 sampled points rather than a description of your lot.

What puts water in a Hartford basement
The ground under Hartford holds water close to the surface: in a typical year the seasonal-high water table modeled from USDA soil survey rises to within about 1.7 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 87 freeze-thaw cycles a year (ERA5) add frost pressure against the wall on top of that.

Roughly 87 freeze-thaw cycles a year add frost pressure on top of that.
