Signs you may need exterior waterproofing & excavation
- Leaks through a wall from the outside
- Want to stop water before it reaches the wall
- Foundation wall needs repair from outside
Exterior work means excavating next to the foundation, so access, landscaping, decks and utilities all matter. Wisconsin law requires contacting Diggers Hotline (dial 811) at least three working days before digging, so utility lines can be marked.

Local conditions
Most basement water comes from the lot itself: soil that stays saturated after heavy rain or snowmelt, downspouts that empty next to the wall, a yard that slopes toward the house, or a sump discharge that cycles back. Saturated soil pushes on foundation walls (hydrostatic pressure), and water finds the joint between the wall and floor, cracks and pipe openings. A good inspection should show you which of these is happening in your home.
