Groundwater & Basement Water Intrusion in Bloomington, 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 melt does more harm than any summer storm.
It almost always does. A winter's snow comes away across roughly two weeks onto ground sealed by frost to a depth of several feet, so none of it can soak in and all of it travels at the surface. A thaw-time rain compounds rather than replaces. Late March is the date to work back from, with a functioning pump and an outlet clear of ice.
Several feet of frost. What does that do to a foundation?
Two things, and the second is the one people miss. It removes the ground as somewhere for meltwater to go, so a fortnight of thaw travels entirely at the surface. It also freezes the moisture in the soil beside a wall, and that expansion presses inward on masonry that does not fully recover when it lets go again.
Four days since the rain and the pit has not stopped.
Ground of this kind lets go of water grudgingly, so the drain around the footing keeps supplying the pit long after the surface and the lawn have dried out completely. The better part of a week is nothing unusual. What justifies looking into is a pit that never rests even across a fortnight without rain, which generally means the outlet is too close.
