Groundwater & Basement Water Intrusion in Poughkeepsie, 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 creek is small and it rose several feet.
A narrow ravine with a wide catchment does exactly that. The channel drains a large built-up area and has very little room to spread, so the level rises sharply rather than the water spreading out. It also drops quickly once the rain stops. The practical consequence is that the event is short and there is no time to move anything, so protection has to be permanent rather than something you do when the rain starts.
Water pushes in at the uphill wall of the basement.
On a slope that is the expected pattern. The uphill side has saturated ground against it and the water arrives under pressure rather than running across the surface, which is why sealing the inside face does not hold. Interception above the house, with a drain that discharges to somewhere lower, addresses it at the source. On a hillside there is usually somewhere lower available, which makes a gravity drain possible and a pump unnecessary.
How much does a September storm differ from ordinary heavy rain?
Enough that the drainage which handles the rest of the year is beside the point. Tropical remnants deliver in a day what the area would normally receive in a month, and the local creeks and storm system have no capacity for that. Design and preparation should be judged against the once-a-year event rather than the average one, because that is the storm that produces essentially all of the damage.
