Groundwater & Basement Water Intrusion in Hanover 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
Everyone on our block had water the same weekend.
That is what uniform construction on former wetland produces. The houses were built in a few years to one specification, they sit at similar elevations on ground that holds water, and the seasonal table comes up under all of them at once. It is not a coincidence and it does not mean your house is worse than the neighbors'. It does mean contractors are committed within hours, so calling early matters more than usual.
Our sump is original. Should we replace it before it fails?
If it is from the original construction, it has long outlived a normal service life and it will fail during a storm rather than on a dry Tuesday. Replacing a pump proactively costs a fraction of a finished basement. While it is being done, check where the discharge terminates, because a line that ends near the foundation recirculates the same water and keeps a healthy pump running continuously.
Does it help to know the land was wetland?
It sets expectations correctly, which saves money. Ground that was wetland drains poorly by nature and holds a high seasonal table; that is not a defect to be fixed but a condition to be managed. Owners who expect a dry basement in April and keep spending on sealants tend to do worse than those who accept the water table and install a drain and sump that handles it reliably.
