Groundwater & Basement Water Intrusion in Dayton, OH
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 does a dry dam differ from an ordinary one?
It holds no permanent pool. The structure sits empty and the river runs through an opening at its base, so it does nothing at all until flow exceeds what that opening can pass, at which point water backs up behind it and is released slowly. The system here was the first of its kind built in the country and it was a direct response to what happened in 1913.
The water table seems very close to the surface.
It is, because the valley sits over a buried sand and gravel deposit that holds a great deal of water and is used for supply. That makes the water table shallow and responsive, so it rises quickly after wet periods. Basements in this valley are often closer to it than their owners realize.
Sewage comes up in the basement during storms.
That points at the combined system serving the older streets, where storm and sanitary flow share one pipe. Rainfall is by far the larger volume, so when the pipe fills the surplus surcharges and finds the lowest connection on the street. The trigger is rainfall and the fault is in the street, not in the fixtures.
