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.


  • 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.


  • 10" high x 4' long
  • THICKNESS: .4", 1", 1 ˝" OR 2"
