Groundwater & Basement Water Intrusion in Duluth, GA

Somewhere to go. A drain laid around a foundation only helps if it discharges to a point lower than itself that is still accepting water, and on a graded lot that point is not always obvious. Where the ground falls away it can run to daylight, which is ideal because nothing has to be powered. Where it does not, it has to reach a pit and be pumped. Establishing the discharge before the trench is dug avoids an expensive ring of pipe with nowhere to empty.

Then it is worth checking whether that strip was doing a job for several lots rather than only yours. Subdivision grading frequently routes water along the boundary, and posts, footings, and a run of fill can interrupt it enough to matter without looking like anything. The recorded plat will show whether an easement sits there. Restoring the profile is usually simple once the question has been asked.

Longer than the visible evidence suggests, because clay releases against the wall for days. A floor that looks dry on the second morning can still be taking moisture through the slab, and finishes put back too early trap it. Take readings on the concrete rather than looking at it, and compare against a part of the basement that never got wet. That comparison is what tells you whether you are finished.
