Groundwater & Basement Water Intrusion in Long Grove, 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 septic field will not accept anything after a wet week.
A field works by letting effluent soak into the ground, and when that ground is already saturated there is nowhere for it to go. On this till that condition can last for days after a storm rather than hours. Trouble confined to the wettest weeks of spring is close to normal here; trouble after ordinary rain means the field has reached the limit of what the site will support.
Should the well be tested after flooding on the lot?
Yes, and promptly, because surface water reaching a well head enters the supply without the filtering the ground would otherwise provide. Use bottled water until a result comes back. The permanent fix is building the ground up around the casing so that nothing stands there, and making sure the cap seals, both of which are small jobs relative to the consequence.
There is no storm sewer. Where is water supposed to go?
Into the low ground and wetland between the lots, which is deliberate and which works as long as those areas stay open. The failure mode here is not a blocked pipe but a filled swale, a new drive across a low point, or a berm built for privacy that also happens to dam the route water was taking. Walking the lot lines during heavy rain shows the whole arrangement.
