Groundwater & Basement Water Intrusion in Rensselaer, 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 damp on some days and not others, with no rain.
Near the waterfront that usually points at the tide. The Hudson is tidal well above here, so the river rises and falls twice a day and groundwater in the fill beside it follows. A cellar cut close to that range is damper at high water regardless of the weather. Comparing when it is wet against a tide table generally reveals the pattern within a week and changes the remedy from hunting a leak to managing groundwater.
Our property was industrial ground. Does that matter?
It can, in two ways worth knowing. Made ground drains unpredictably because it is fill rather than natural soil, so water can move in ways the surface does not suggest. And what is in that fill varies, which is worth establishing before excavating for drainage work. Neither is a reason for alarm, and both are reasons to find out what is there before committing to a below-grade solution.
Why do the lowest blocks flood in a hard rain?
The streets step up steeply from the waterfront, so runoff from the whole slope concentrates at the bottom and arrives together. It is a surface mechanism entirely separate from the river, and it can happen at low tide on an unremarkable day. Properties on the lowest blocks are exposed to both mechanisms, which is why they can flood in circumstances that seem inconsistent.
