Groundwater & Basement Water Intrusion in Butte, MT
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
Water appears in the cellar with nothing wet uphill.
In mining country that is common. Old workings and the fractured ground around them carry water along routes that have nothing to do with the surface slope, so a discharge can emerge well away from where any rain or melt occurred, and on a schedule of its own. Surface grading often makes little difference. Interception at the wall, with a drain and a sump sized for continuous running, is usually the practical answer.
The water leaves a stain and corrodes things.
Water that has moved through old workings carries dissolved metals and is frequently acidic, which is why it stains what it touches and eats at anything metal sitting in it. Fasteners, ducting, and the bases of appliances all suffer. Porous material that has been submerged in it is generally removed rather than cleaned, and metal that stays needs inspecting rather than assuming. Drying alone leaves the corrosion going.
What is the biggest winter risk in a house here?
A frozen supply line. At this elevation the freezing season is long enough that any plumbing in an unheated or under-heated space will eventually freeze and split, and the release comes on the thaw at full pressure. Draining the system for any extended absence prevents it entirely. Where a house is heated remotely, a low-temperature alarm is cheap against what a burst line costs.
