Cavity Weep Highlights

Cavity WeepTM is superior to other weep hole/weep vent products because it creates multiple tunnels allowing water to exit the cavity by running on the top surface of the flashing.  It puts the weep holes at the lowest point of the wall, beneath the bed joint of mortar!


  • It forms the bottom side of the bed joint of mortar creating 4 weep holes every 9.5”
  • Doesn’t impede the flow of water or create artificial dams that impede drainage
  • Installs quickly saving time and money
  • Translucent in color to blend with mortar

Cavity Weep Installation

  • Place bed joint of mortar on Cavity WeepTM and lay masonry units
  • Tool joints and lightly score legs at face of wall; crack off by pushing downward while mortar is still plastic
