What Core Cavity Weep does:

  • It forms the bottom side of the bed joint of mortar at the exterior and interior shell of a CMU or Jumbo Brick
  • It weeps both the core and cavity when CMU or Jumbo Brick is used as a veneer
  • It’s easy to install (12" wide — 25' long rolls)
  • It is translucent in color and blends with mortar.

How to install Core Cavity Weep*

  • Core/Cavity Weep should be positioned on flashings and waterstops with material centered on wall. Allow intermittent legs to extend into the wall cavity and to the exterior as illustrated.
  • Apply bed joint of mortar.
  • Install masonry units on bed of mortar, following normal installation procedures.
  • Lightly score legs at face of wall, crack off by pushing downward while mortar is still plastic.
  • Tool and finish mortar joints.
