Shell Busey shows you how to repair your basement vapour barrier.

Apply a bead of acoustical caulking on a chalk line snapped on the concrete wall 6 inches above grade level outside. Apply 6 mil poly onto the acoustical caulking rolling it down the wall and up in front of insulation to the top of the wall out onto the ceiling 12 inches and tape to ceiling vapour barrier.

Don’t forget the insulation between the joists on top of the wall up against the rim joist sealed with 6 mil poly and acoustical caulking.
