Groundwater & Basement Water Intrusion in Hamilton, 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
The flood control system has held for a century. Why is the basement wet?
Because it holds back the channel rather than the groundwater. During prolonged high flows the water table across the valley fill rises with the river and reaches basement floors from below, through the slab and the floor joint. Nothing has overtopped and nothing has failed. It is the most commonly misunderstood situation in a protected valley, and it is why an interior drain and a sump still earn their place.
Does local rainfall behave differently when the river is up?
It does, and that catches people out. Storm drainage discharging toward a high river has no head to push against, so it backs up and streets hold water from ordinary rainfall while the works are performing exactly as designed. The two conditions are linked, and the drainage only starts working again once the river drops rather than when the rain stops.
Our basement has never had tile. What is realistic?
An interior perimeter drain and a sump, which gives arriving water somewhere to go other than the finished part of the basement. Houses of this era were built without tile, so the wall is doing all the work and it weeps whenever the table rises. It is disruptive to install, and on this ground it is the change that most reliably alters the outcome.
