Inside the wall

Interior Waterproofing That Captures Water and Sends It Away

Interior work accepts that some water will reach the wall, then gives it a controlled route to a sump or drain instead of the basement floor.

Common warning signs

  • Seepage along the seam where floor meets wall
  • Damp patches that widen during spring melt
  • Efflorescence behind stored boxes or shelving

Common causes

  • Hydrostatic pressure lifting water through the floor joint
  • Blocked or undersized original drainage
  • Hairline shrinkage cracks in poured walls
  • Sump systems that cannot keep up with volume

How it works

How Interior Waterproofing Is Carried Out

  1. 01

    Open a channel along the interior perimeter where seepage is documented.

  2. 02

    Set drainage pipe in stone and tie it to a sump or existing drain.

  3. 03

    Apply membrane or a drainage board against the wall face.

  4. 04

    Restore the concrete and test the flow path.

Possible waterproofing methods

  • Interior drainage channels
  • Dimpled wall membranes
  • Crack sealing and injection
  • Sump pump connections
  • Floor drainage improvements
  • Humidity and moisture management

Benefits of addressing it

  • Work stays inside, so landscaping is untouched
  • Often the quicker route to a usable basement
  • Handles water arriving from more than one direction
  • Pairs well with later exterior work if needed
