Groundwater & Basement Water Intrusion in Williamsport, PA
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
Everyone here dates things from the 1972 flood.
That event is the local benchmark and it is worth knowing that the defenses predate it and were overtopped by it. Treating a single remembered flood as the ceiling is the common mistake, because it was a level that had not happened before either. The design figure and the record figure are different numbers and both are published.
The river gives a day of warning and the creek gives none.
They are separate hazards that happen to share a city. The West Branch reflects rain over a large area of ridges and is forecast well ahead, so there is time to act. A summer cell landing on a hillside street fills a cellar in twenty minutes with nothing issued beforehand. Preparing for one does very little about the other.
It has been dry here for a week and the river is climbing.
What fills this river falls over a very large area of forested ridges upstream, sometimes a hundred miles away, and it takes a day or more to arrive. Watching the sky over town tells you very little. The gauge forecast for this reach is the number worth following, and it gives useful notice rather than a few hours.
