Groundwater & Basement Water Intrusion in Laconia, 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 lakes are large. Do their levels vary?
Less than a river would, because they are big and their outlets are managed, and that stability is genuine. What matters more here is the short channels connecting them: they have limited capacity, so when a large lake is discharging into a smaller one the level in between can rise noticeably. The narrow bits move more than the wide ones.
Much of the city sits between two bodies of water.
It does, and that means a great deal of the built ground is close to lake level with water on more than one side. Elevation relative to the lakes is the useful number for any address, and it varies over short distances. Distance from a shoreline says much less here than height above it.
It is always October when something goes wrong.
Autumn brings systems carrying a great deal of moisture that stall against the high ground around, and the ground by then has less capacity than in summer. Add leaves blocking inlets and the outcome exceeds what the rainfall figure suggests. The events people here remember are mostly from that season.
