Mortar Trap™

Mortar Trap™ is manufactured from high-density polyethylene (HDPE) strands woven into a 90% open mesh. Its unique shape breaks up mortar droppings and prohibits mortar from creating a moisture retaining barrier, allowing water to flow freely to the weep holes.


10″ high x 4′ long
THICKNESS: .4″, 1″, 1 ½” OR 2″

NOTE: When Mortar Trap™ is used with the Quadro-Vent™ Weep Hole additional insect screening is not required.

  • 90% open mesh construction allows unobstructed passage of air & water through the material itself so walls breathe, drain & dry quicker
  • Will not react with common building products (PVC, polystyrene, copper, rubberized-asphalt, lead, stainless steel or galvanized metal)
  • Will not: absorb or trap moisture, support mold or fungus, and is inedible to insects
  • Will not degrade as a result of temperature variations and is designed to last for the life of the building
  • Keeps weep holes open – catches and permanently suspends mortardroppings so blockage can’t occur
  • Fast, easy installation by masons – does not require fasteners or adhesives, no special skills or tools
  • Slightly compressible to allow for cavity variations in the field
