Groundwater & Basement Water Intrusion in Claremont, 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 drops a long way through the middle of this city.
It does, over a series of old structures built to drive the mills, and each one holds the level of the reach above it permanently rather than seasonally. That means the ground beside a pool never gets an interval with the pressure off, which is a different problem from a river that rises and falls with the weather.
There is old mill stonework in the river and no obvious owner.
Ownership of these structures is often genuinely unresolved, because the companies that built them are long gone and the records went with them. The state keeps a register of dams and that is where to start. Where nothing traceable turns up, the state is the only body with any power to act, and reporting a deteriorating structure is worth doing.
The mains under this city were sized for a bigger place.
That is the position and its consequences are worth stating. There is more buried infrastructure per household here than the population would suggest, all of it older than average, kept in repair by a tax base that has shrunk along with everything else. On the drainage side that appears as capacity which is real on a drawing and uncertain underground.
