Where each walk sits in the schedule

Below-grade waterproofing rough-in inspection checklistrough-in
After the wall is stripped and cured and details are patched, before the membrane goes on and while every detail is still reachable. Run by: The waterproofing foreman checking the wall ahead of the membrane crew, or the GC's superintendent releasing the foundation for waterproofing.
Below-grade waterproofing final inspection checklistfinal
After the membrane is complete and any adhesion or flood test is done, immediately before protection board and backfill go on. Run by: The GC's superintendent with the waterproofing foreman, releasing the wall for backfill.
Below-grade waterproofing punch checklistpunch
During closeout or after a leak shows up, while there's still access to the affected area of wall. Run by: The waterproofing foreman on a callback, or the GC's superintendent closing envelope punch below grade.

What most often sends below-grade waterproofing work back

  • Membrane applied to green concrete or a damp wall, so it never bonds and blisters off below grade.
  • Tie holes and honeycomb patched with a quick smear instead of the detailed treatment, leaving a path straight through the wall.
  • No cant or fillet at the footing-to-wall corner, so the membrane bridges a sharp inside angle and cracks there.
  • Backfill dumped against the membrane before protection board is on, gouging the coating with rock and debris.
  • Sheet laps run short or shingled the wrong way, so water tracks into the overlap instead of over it.
  • Termination at the top of wall left unsealed or unbattened, so water gets behind the membrane from above.
  • A leak chased at the interior wet spot while the actual breach in the membrane is somewhere else along the wall.
  • Footing drain choked with fines or disconnected at the tie-in, so water stacks against the wall no matter how good the membrane is.
