Groundwater & Basement Water Intrusion in Bloomington, IL
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 basement stays wet for days after the storm has gone.
Prairie soil parts with water slowly, so the seasonal table rises during a storm and takes days rather than hours to fall. The wall and the floor joint stay under pressure long after the weather cleared. A sump running steadily through that period is doing its job; what is not normal is one that never rests even in dry weather, which usually points at a discharge line ending too close to the house.
There is no tile under our house. Is retrofitting worthwhile?
On this soil it is usually the single most effective change available. Houses of this era were built without tile, so the wall is doing all the work and it weeps whenever the table rises. An interior perimeter drain to a sump gives the water somewhere to go other than the finished part of the basement. It is disruptive because it means opening the slab edge, so it pairs well with other planned work.
It arrives at the floor rather than down the wall.
That is pressure from beneath rather than runoff from outside. When the table rises above the slab, water finds the joint where floor meets wall and sometimes cracks in the floor itself. Gutters and grading do not reach it because the water is not arriving from above. Drainage capacity below the slab is what changes that specific symptom, which means tile and a pump.
