Groundwater & Basement Water Intrusion in Milwaukee, WI
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 crack in the basement wall has been there for years. Why does it leak only in June?
Freeze-thaw widens it all winter, and June is when the volume arrives. Water in the crack expands each freeze, then 4.84 inches finds a path that was still tight in November. Nothing changed suddenly; the joint reached the width where it stops holding water and starts letting it through. Keep the grade and downspouts off that wall; an interior bead of sealant does not close a path that starts in the yard.
We have an ice dam every winter. Is that putting water into the house or just onto the yard?
Into the house, once melt ponds behind the ice. Heat escaping the attic melts snow higher up; it refreezes at the cold eave and holds standing water under shingles built only to shed. That water runs the deck and shows as a ceiling stain. Extraction of the wet ceiling and a moisture map of the cavity come first; attic air sealing is what stops the next dam from forming.
This is a duplex. The stain is on their ceiling and our party wall. Where does extraction start?
On the wet material, not on the deed. Water follows the shared masonry and the roof valley, so the stain you see may have entered two rooms over. A local pro maps both sides of the party wall and the gutter line before anyone opens one parlor. Standing water in the wall keeps feeding both units until the cavity is extracted and dried, which is why waiting on ownership only widens the job.
