Groundwater & Basement Water Intrusion in New Rochelle, 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
Which kind of flooding does this address get?
It is the first question worth answering, because the remedies do not transfer. On the shoreline the water arrives with the tide behind a coastal storm and the work is about elevation and barriers. Inland it arrives as runoff within minutes of a cell and the work is about drainage capacity and what enters the sewer. Advice for one is close to useless for the other.
The system is holding water and the sky has been clear for hours.
That is the tide rather than an obstruction. While the water at an outfall stands above the pipe, nothing can leave through it, so the whole line sits full until the level drops away again. It is worth knowing because the danger is the overlap: rain landing during those hours has no route out at all, and that coincidence is what puts water in the low streets.
Where is all the additional water in the sewer originating?
Chiefly on private ground rather than in the roadway. Downspouts piped into house drains, footing drains joined to the same line and old laterals with joints open enough to admit groundwater all feed it, and in stock of this age a great many were arranged identically. Taking one downspout off that line is among the few unilateral acts that also helps downstream.
