Groundwater & Basement Water Intrusion in Keene, 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
How does a valley position change the risk?
It concentrates everything. Rain falling anywhere on the surrounding hills is funneled toward the same valley floor, and there is nowhere for it to spread once it arrives. A storm total that would be unremarkable spread over flat country becomes significant when the whole catchment delivers to one confined area.
The worst events seem to come in autumn.
Autumn brings systems with a great deal of moisture that can stall against high ground, and the ground by then has less capacity than in summer. Add leaves blocking inlets and the combination is worse than the rainfall figure alone suggests. The events people here remember are mostly from that season.
The river runs right through the center of town.
It does, and the oldest and lowest parts of the city are built along it because that is where the settlement started. That puts the stock with the least protection on the ground with the least margin. The buildings are not deficient; they reflect where a town of that era chose to put itself.
