Groundwater & Basement Water Intrusion in Duluth, 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 flow overshoots every inlet on the way down.
Water on gradients like these is moving quickly well before it reaches a grate, and the greater part of it simply passes over. That is a design limit rather than an obstruction, although leaves across a grate convert the limit into a flood. Below a steep run the effective work is at the boundary, lifting flow out of the entrance.
The ground is solid rock. Should it not be dry?
Frost here reaches well below anything buried at ordinary depth, which is why a discharge line laid to normal cover is solid ice in March, exactly when the melt is asking the most of a pump. Extending it, giving it fall, or lifting it clear for the season is what stops the water coming back inside.
The stream at the back is cutting toward the house.
Streams here work backward at their heads, wherever runoff has been gathered into one stream, and the culprit is generally a downspout, the edge of a drive or a pump outlet discharging over the rim. Moving that discharge back from the edge and letting it spread is what arrests it. Work on the face itself will not hold while the flow continues.
