Interior Waterproofing

$120 – $300 per linear foot

Interior waterproofing manages water after it enters the wall assembly and removes it before it can damage your basement. It is the ideal solution when exterior excavation isn’t possible — attached garages, tight lot lines, decks or finished landscaping.

We cut a channel along the interior footing, install perforated drainage pipe in a gravel bed, add a dimpled membrane up the wall, and route everything to a sealed sump pit. The floor is then re-concreted flush for a clean finish.

What’s included

  • Interior drainage channel and weeping tile
  • Wall membrane directing moisture to the drain
  • Sump pit and high-capacity sump pump
  • Floor restoration with new concrete
