Groundwater & Basement Water Intrusion in Oak Park, 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
Sewage came up in the basement and the street outside was dry.
Then it is the main under the road rather than the ground around the house, and the money belongs somewhere different. A pipe that has filled relieves through whichever connected opening is lowest, and in this stock that is the basement drain. Grading and downspouts change nothing about it; a valve or an overhead conversion does.
The damp wall is the one facing the house next door.
That elevation is receiving two roofs into a strip only a few feet across, and there is usually nowhere for any of it to go. The gap tends to be level, often paved over, and both properties frequently discharge downspouts into it. Because the ground and the water are shared, nothing gets resolved without the neighbor, which is why these run on for decades.
These are large roofs on modest lots.
They are, and that is the arithmetic worth doing. A roof of this size sheds a great deal into a small amount of receiving ground, and none of it soaks away quickly on this soil. Working out the roof area and where each downspout puts its water explains most of what a pit is dealing with, and it usually points to a cheap change.
