Basement Waterproofing in Oshkosh, WI

Soil and water in Oshkosh

Glacial Lake Oshkosh inundated most of Winnebago County and coated much of it with fine-grained clay and silt, and many low-lying areas are wetlands because of that relatively impermeable soil and very low relief.

Oshkosh is on the west shore of Lake Winnebago where the Fox River enters it, and it's the Winnebago County seat.

Common basement waterproofing calls

• Water on the floor after heavy rain or snowmelt
• Damp walls or white mineral deposits (efflorescence)
• Musty smell in the basement
• Planning to finish the basement and want it dry first

There are two broad approaches: managing water that gets in (interior drain tile and a sump pump) or stopping it at the wall from outside (excavation and exterior membrane). A local pro can inspect and explain which fits your home.
