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
- 01
Open a channel along the interior perimeter where seepage is documented.
- 02
Set drainage pipe in stone and tie it to a sump or existing drain.
- 03
Apply membrane or a drainage board against the wall face.
- 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
