Why Waterproofing Matters in Lyndon

In the Southeast, waterproofing is rarely just about keeping rain out β€” it is about managing groundwater that rises seasonally and storm bursts that overwhelm yard drainage in minutes. A sealed crawl space without drainage will flood from below during heavy storms because hydrostatic pressure pushes groundwater up through the substrate. Interior perimeter drains and a sump pump are the standard fix.

What a Lyndon Waterproofing System Should Include

  • βœ“Interior perimeter drain channel along footings (1.5–2 inch radius)
  • βœ“Sump pit and pump (1/3 to 1/2 HP, with battery backup)
  • βœ“Discharge line routed at least 10 feet from foundation
  • βœ“Vapor barrier (12–20 mil) over the drain system
  • βœ“Exterior French drain if the lot grades toward the home
  • βœ“Hurricane-rated check valve on discharge line

Interior vs Exterior Drainage in Kentucky

Recommendation

Interior perimeter drains are the primary line of defense in the Southeast. Exterior French drains help but are not sufficient alone β€” Southeast soil saturation defeats them during heavy storms.

Sump Pump Sizing

A 1/2 HP sump pump with battery backup is standard in this region. Power outages are common during the storms that create the most water β€” a battery backup is non-negotiable. Expect to replace pumps every 7–10 years.

What to Watch For in Kentucky

  • !Reject any waterproofing quote that does not include a sump pump in the Southeast
  • !Confirm the discharge line cannot back-flow during a flooded yard scenario (check valve required)
  • !Pair with encapsulation β€” sealed crawl space + drainage is the long-term Southeast standard
