Groundwater & Basement Water Intrusion in Nampa, ID
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
There is a large irrigation reservoir beside the city.
There is, and it is filled from the river in spring and drawn down through the summer to supply the canals, so its level is an operating decision rather than a season. Ground water nearby follows it. A property close to that shore can be wet in June and dry in October for reasons entirely unrelated to the weather.
The creek through downtown runs underneath the street.
For part of its length it does, put into a culvert as the city built over it, and the limitation with any buried channel is that nobody can see inside. It has exactly the capacity it was given, less whatever has collected since. The city's records are worth asking for, along with where the surplus goes when it is full.
The basement was dry for ten years and now it is not.
When the land around changes use, water that used to be spread across fields gets concentrated instead, and the level in the ground nearby can settle at a new height. Nothing about the house changed. That distinction matters because a one-off event calls for a repair while a permanently higher level calls for a drain and a pump.
