Groundwater & Basement Water Intrusion in Derby, CT
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 side of the levee line does this address sit on?
It is the first thing worth settling and it is not obvious standing in the street. Protection covers a defined area and stops, so two houses a short distance apart can have completely different exposures and completely different insurance positions. The city and the flood mapping both show the line, and looking is considerably better than assuming.
The smaller river flooded and it was not carrying much.
When the larger river is high it holds the smaller one back, so the smaller cannot discharge and floods upstream of where they meet without any unusual flow of its own. That is why a property well up the tributary can be caught by an event that is entirely about the other river, and why watching both gauges rather than one is the habit worth having.
The barrier did its job and the cellar filled regardless.
With the outfalls shut, rain landing inside the protected ground has no gravity route out and must be lifted over by pump, while the high river simultaneously raises the water beneath the whole area. It arrives through floors and floor drains rather than over any bank. The levee deals with the river; the water underneath it is a separate matter.
