Groundwater & Basement Water Intrusion in Bemidji, MN
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 great river starts here rather than passing through.
Which makes it a small stream at this point rather than the river people picture, so it responds to local rain within hours and carries very little. The hazard here is almost never the river itself. It is the lakes, the wetland and the melt, and confusing the name with the risk misdirects a good deal of worry.
Frost goes deeper here than almost anywhere.
Several feet in an ordinary winter, which is why anything buried has to sit below that depth or be built to tolerate freezing. The consequence people meet is at the outlet: a pump discharging into a line laid at ordinary depth finds it solid ice in March, exactly when the melt is asking the most of it.
The ground here is peat over much of the area.
Peat holds an enormous amount of water and gives it up slowly, and once it is drained and exposed it oxidizes and the surface goes down. A lot that sat comfortably above its ditch when a house was built can be level with it decades later, with nothing having failed. It is a slow change rather than an event.
