Groundwater & Basement Water Intrusion in Caldwell, 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
The crawl space is wet in August and dry in February.
That is the irrigation season rather than anything wrong with the house. Canals running full from spring through autumn hold the level in the ground alongside them up for months, and it falls once they are shut off for the winter. It looks backwards to anyone used to a rainfall climate. Matching when the wet appears against when the district runs water settles it within one season.
There is a lateral along the boundary. Who looks after it?
An irrigation district or a canal company rather than the city, and they hold rights along it that predate most of the housing here. That cuts both ways: they can require access along the bank, and they are also the people to talk to about seepage or an overtopping. Establishing which entity holds the lateral, and what the easement covers, is worth doing before there is a reason to.
Twelve inches of rain. Where is the water coming from?
Almost entirely from the canal system rather than from the sky, which is why this ground behaves nothing like its rainfall figure suggests. Water has been delivered across this valley every summer for a century and the ground beneath is wetter for it. Reasoning about drainage here from the annual precipitation is the most common mistake made on these properties.
