Annual precipitation: 30–50 inches; concentrated in spring and summer storms.

Why Waterproofing Matters in Center Line

Midwest waterproofing has to handle two distinct events: spring flash floods that drop 2–4 inches in an hour and clay soils that expand seasonally, holding water against foundations like a slow-release sponge. Tornado and severe-storm damage adds an emergency dimension β€” interior drainage that survives without power is critical. Pair with radon mitigation if levels are elevated (most of the Midwest is in EPA Zone 1).

What a Center Line Waterproofing System Should Include

  • βœ“Interior perimeter drain (1.5–2 inch radius)
  • βœ“Sump pump with battery backup (severe-storm power loss)
  • βœ“Discharge line with check valve
  • βœ“Vapor barrier and radon-rated barrier seams if Zone 1
  • βœ“Exterior French drain only if soil permits (heavy clay limits effectiveness)
  • βœ“Reinforced barrier in tornado-prone counties

Interior vs Exterior Drainage in Michigan

Recommendation

Interior is mandatory in clay soils. Exterior French drains can clog or crush in expansive clay within 5–10 years. Budget for interior-first systems and treat exterior grading as a complement, not a primary defense.

Sump Pump Sizing

A 1/3 to 1/2 HP pump with battery backup is standard. Severe weather brings 6–24 hour power outages multiple times per year β€” battery backup is non-negotiable. Consider a water-powered backup pump in flood-prone areas.

What to Watch For in Michigan

  • !Test radon BEFORE waterproofing β€” bundle systems if levels are elevated
  • !Demand battery backup on sump pump given severe-storm power loss patterns
  • !In tornado country, route discharge lines underground rather than on exterior walls
