Groundwater & Basement Water Intrusion in Jamestown, ND
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 rose and there had been no weather.
Below two structures the level answers to release decisions and to conditions across the catchments upstream rather than to anything happening overhead. Those decisions are published and explained in advance. For anyone near the water they are considerably more informative than the local forecast, and they give notice measured in days rather than hours.
Two reservoirs and two rivers. Which one matters?
Whichever is upstream of the property, and below the meeting point both. The two catchments differ in size and shape, so a wet spring can fill one substantially while the other stays ordinary, and the highest levels come from the occasions when they arrive together. Flood mapping for a specific address answers this far better than following a single number.
The reservoirs above are drawn down before the melt arrives.
That is deliberate: emptying storage through the late winter creates room for what is about to come off the fields, and the schedule is set by an agency rather than by the weather. For a city below them it means the level in the river reflects decisions taken weeks earlier, and those decisions are published if anyone wants to follow them.
