Groundwater & Basement Water Intrusion in Eagan, 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
What is a landlocked basin?
A low area with no stream leaving it. Water arrives from the surrounding ground and the only ways out are evaporation and soaking into the soil, both of which are slow. Through a wet year the level rises steadily and stays high, which is why some ponds here sit well above the level residents remember from a decade ago.
The pond behind the house is bigger than it used to be.
On a closed basin that is entirely possible and it is not necessarily temporary. A run of wetter years puts in more than evaporation takes out, so the level steps up and holds. Houses sited relative to the old shoreline can find the water considerably closer without anything having been built or changed nearby.
The worst of it is in early spring.
That is the frozen ground. A winter of snow melts over a few days onto soil that is still frozen and cannot absorb any of it, so effectively all of it runs off or ponds. In a landscape of closed basins that meltwater collects in the low spots and then has to wait there for the ground to thaw.
