Groundwater & Basement Water Intrusion in Lebanon, 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
Sinkholes open in the fields around here.
They do, because this is a limestone valley and the rock is dissolving along joints and bedding planes. It is a genuine local condition rather than a general caution, and it affects drainage as much as ground stability. Water can leave a property through the rock and arrive somewhere with no surface connection to it.
A wet patch appeared in the yard with no source.
On this ground that is worth taking seriously. Limestone carries water along channels that surface contours do not predict, so a seep can emerge from a route running well beneath neighboring properties. It also means a change in where water appears can indicate the rock below has changed rather than anything above it.
The cellar floor is uneven rock in places.
That is common where these houses were founded directly on irregular limestone. It means there is no continuous slab or membrane to work against, and water entering through the rock arrives inside the space rather than beneath a floor. Treating it as a conventional basement generally leads to the wrong remedy.
