Groundwater & Basement Water Intrusion in Norwich, 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
Three rivers and the tide all meet here.
They do, and that is the defining condition. Fresh water arrives from three catchments of different sizes and timings, and the tide sets how easily any of it can leave. The worst combination is heavy upstream flow meeting a high tide, when the water coming down has nowhere to discharge to.
Why is March the wettest month?
The rainfall is fairly even across the year, but March adds snowmelt and takes away the ground's ability to absorb any of it. Soil is still frozen at depth, so meltwater and rain both run off almost entirely. The combination rather than the rainfall alone puts March at the top.
The ground is rock a short way down.
On the slopes above the rivers that is common, and it removes most of the storage. Thin soil over rock fills within minutes, and then water travels along the rock surface toward the valley, arriving at cellar walls from the side rather than from below. It reaches a shallow cellar as readily as a deep one.
