Groundwater & Basement Water Intrusion in Dover, NH
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 river behaves differently on either side of the falls.
It genuinely does, and it is the most useful distinction to draw here. Above the drop it is a freshwater river responding only to rainfall in its catchment. Below it the level is set largely by the tide, so a property there can see high water on a dry day and the two halves of the city need thinking about separately.
The oldest housing is right against the river.
That is where the mills were, and the housing followed the work. It means the stock with the least drainage protection sits on the ground with the least margin, which is the usual arrangement in a mill city. It reflects nineteenth-century priorities rather than any failure of construction.
Why is autumn the worst season rather than spring?
Autumn brings coastal systems that deliver moderate rain for a day or more while the ground is still relatively warm and the leaves are blocking inlets. Spring has snowmelt, which is a real mechanism, but it is more gradual. The October pattern combines duration, saturated ground and blocked drainage in a way no other season does.
