Why Chicagoland basements flood
Will, Cook, and DuPage clay does not drain. Combine that with snowmelt, a two-day rain, and a sump that cannot keep up, and water finds the basement. Ice dams send melt under shingles. Foundation cracks from freeze-thaw open a path. We see the same pattern from Homer Glen to Joliet, Naperville, Plainfield, and Bolingbrook.
