Groundwater & Basement Water Intrusion in New London, 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
The Sound is sheltered compared with the open ocean.
It is sheltered from the waves and not from the level. A storm pushing water from the south drives it into a body with a restricted outlet, so the level rises against the shoreline regardless of the shelter. The wave protection is real and it does nothing about surge.
The low streets flood and the hill above them does not.
That is the shape of the city working as expected. Ground rising steeply from the harbor concentrates everything falling on it into the few blocks at the bottom, which are also the blocks closest to tidewater. Those streets get both the runoff from above and the drowned outfall below at the same time.
Does the tide matter if the storm is only rain?
It matters whenever the outfalls are tidal, which here they are. At high water the drains cannot discharge, so rain that arrives in that window backs up in the system regardless of how ordinary the storm is. The same rainfall six hours later often passes through with no trouble at all.
