Groundwater & Basement Water Intrusion in Briarcliff Manor, 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 damp wall is the one holding back the hill.
It would be, because that side is retaining ground that stays wet for most of the year while the opposite face of the house is open to the air and dries. The imbalance is permanent rather than seasonal. On a lot with a fall to it the usual answer is a drain at the uphill footing taken out to daylight, which avoids depending on a pump at all.
The driveway acts like a stream during heavy rain.
A cut drive is the deepest channel on a steep property, so everything coming off the slope above finds it and follows it down to whatever is at the bottom, which is generally a garage or the low corner of the house. That is a consequence of the layout rather than a defect. A cross channel near the top, with somewhere for its catch to go, intercepts the flow before it gathers speed.
The gutters were cleared in October and they are full again.
On a wooded lot one clearing is rarely enough, because oaks hold their leaves into December and drop them well after everything else. A downspout that closes in November concentrates a large roof onto one patch of foundation soil for the whole of the wet spring. The second clearing, late, is the one that matters and it is the one most often skipped.
