Groundwater & Basement Water Intrusion in Hudson, NY
Basement seepage, failed sumps, and hydrostatic pressure against the foundation are extracted and dried, and the path from the ground is identified so the loss does not repeat. Groundwater and basement seepage are extracted and dried only after the path from the soil is identified — a wall, a slab, a drain, or a failed sump. Drying the interior without stopping that path returns the same water to the same floor.
Frequently asked questions
The cellar is wetter on some days than others with no rain.
The tide is the likely explanation, and it surprises people this far from the ocean. The Hudson is tidal well above here, so the river rises and falls twice a day and the groundwater in the fill beside it follows. A cellar cut close to that range will be damper at high water. Noting the times against a tide table usually reveals the pattern within a week, and it changes the remedy from chasing a leak to managing groundwater.
Can a nineteenth-century stone cellar be made dry?
Manageably damp is the honest target. There is no continuous surface to seal on a rubble wall, and interior coatings tend to move water into the floor joint or the mortar higher up. Keeping roof and surface water away from the outside, then handling what still arrives with an interior drain and a sump, is what works. Planning a finished room down there is what leads to expensive disappointment.
Why do the lowest blocks flood when it rains hard?
Because the streets step steeply up from the waterfront, so runoff from the whole slope concentrates on the bottom of the hill. It arrives quickly and it arrives together. That is a surface mechanism rather than a river one, and it can happen at low tide on a day the river is unremarkable. The two mechanisms are separate, and properties on the lowest blocks are exposed to both.
