Groundwater & Basement Water Intrusion in Largo, FL
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
How much difference does the ridge make?
A great deal, and it explains most of the variation between one street and the next. The high ground along the peninsula is only a few feet above what lies either side of it, but a few feet is decisive on land this low. Properties on it drain in both directions and have never taken water; those just off it sit at the bottom of everything the ridge sheds.
Ten inches in a month. Is that really the figure?
It is, and averaging it away is the mistake. A month like that leaves the ground at capacity for weeks together rather than briefly, so an afternoon storm at the end of July behaves nothing like the identical storm in April. Systems that cope easily in the dry season are simply overwhelmed once the profile is full, and that is seasonal rather than defective.
The drain in the street is holding water and the rain has stopped.
Check what the tide is doing before assuming a blockage. An outfall discharging into tidal water cannot flow while the level at its mouth stands above the pipe, so the system holds whatever is in it until the tide drops. Nothing has failed. It matters because rain arriving inside that window has no route out at all.
