Groundwater & Basement Water Intrusion in Columbus, IN
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 levee held and the basement filled anyway.
Because the two are different things. A levee is built to keep the channel out; the water reaching your floor came up from beneath it. Prolonged high stages raise the water table across the whole bottomland, and it enters through the slab and the floor joint. Nothing overtopped and nothing failed. It is why a sump and an interior drain remain worth having on protected ground, and why owners are so often surprised by it.
Is the timing of the two rivers something we can follow?
Yes, and it is more informative than a single downstream number. Each drains a different basin, so a storm centered over one can raise it while the other stays low, and the worst case is when both peak together. Following both gauge forecasts gives a clearer picture of what is coming, and the difference between coincident and staggered peaks often decides whether the bottomland floods at all.
What should we do about the pump when the river is up?
Make sure it can keep running, because that is the period when it matters most and when power is least reliable. A backup on independent power is the main thing. It is also worth knowing that a sump discharging into ground that is already saturated will achieve less than usual, so managing expectations about how dry the basement can be kept during a prolonged high stage is part of planning for it.
