Groundwater & Basement Water Intrusion in Pontiac, MI
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 house next door came down and this one started taking water.
Look at how the cleared lot behaves rather than at the paperwork. Ground that was properly filled and compacted sheds water evenly; ground that was pushed back into a hole settles into a shallow dish, and the outline of standing water after rain traces the old foundation exactly. Photographing that outline is what makes the case to the city concrete.
There is an old sewer connection under the empty lot.
Very possibly, and the city can usually say. Tap records list where each property was connected to the main and when, and an abandoned connection that was never sealed at the main keeps taking ground water in and passing it along. Getting that record for the neighboring parcel costs nothing and is the fastest way to rule it in or out.
The lake has been higher for several years.
Levels in these lakes reflect accumulation across seasons rather than any single storm, so a run of wetter years lifts them past anything in recent memory and they then stay up. That changes what the ground around them does for a long stretch rather than for a weekend, and it is worth treating as a multi-year condition rather than an event.
