Exterior Foundation Waterproofing

Stopping water before it ever reaches the footing.

How much does exterior foundation waterproofing cost in the Triangle?

Exterior foundation waterproofing in the Raleigh area costs $4,000 to $15,000. Crews excavate to the footing, apply a membrane coating, install French drains and footing drain tile, and regrade the lot so runoff moves away from the crawl space.

What the scope includes

  • Excavation to footing depth with membrane or elastomeric coating
  • Footing drain tile bedded in washed stone with filter fabric
  • Downspout extensions and yard drains routed to daylight
  • Positive grading of six inches over the first ten feet

Signs you need this

  • Water entering through the block wall, not the floor
  • Downspouts dumping beside the foundation
  • Negative grade sloping toward the house
