Groundwater & Basement Water Intrusion in Hornell, 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
We are behind the levee. Why is the cellar wet?
Because a levee holds back the channel, not the groundwater. When the river rises, the water table in the valley fill rises with it, and it reaches cellar floors through the slab and the wall joint from below. Nothing has overtopped and nothing has failed. It is one of the most commonly misunderstood situations in a leveed town, and it is why interior drainage and a sump still matter behind a levee.
How fast does the river come up after rain?
Quickly, because the watershed is steep and narrow. Rain becomes river flow in hours rather than over a day, so the interval between a heavy storm and a peak is short. That argues for acting on the rainfall forecast rather than the gauge, and for keeping anything that matters out of the cellar as a standing arrangement rather than a response.
Can an old stone cellar be made dry?
Manageably damp is the realistic target, and that is achievable. A rubble or early poured wall has no continuous surface to seal and coatings applied inside tend to move the water rather than stop it. What works is handling it: an interior perimeter drain to a sump that can run when it needs to, plus keeping roof and surface water away from the outside. Expecting a finished, dry room out of that space is what leads to disappointment.
