MortarNet™ with Insect Barrier™ | The Original Mortar Dropping Collection Device

In masonry cavity walls, mortar collection above the flashing and weep hole levels is vital for proper masonry cavity wall performance and to prevent water damage. MortarNet suspends mortar droppings above the flashing and weeps so they stay clear and unobstructed. Its 90% open mesh allows moisture to flow to the weeps and air to move within the cavity to promote drying. By using MortarNet for mortar suspension and collection, cavity walls perform the way they're designed and walls stay dry and trouble-free.


  • Dual levels
  • Trapezoidal shape
  • 90% open weave mesh
  • Patented Insect Barrier
  • 0.4″ and 1.0″ made from 0% pre-consumer recycled nylon
  • 2.0″ made from 20%-36% post-industrial and 12%-24% post-consumer

MortarNet with Insect Barrier available in 0.4, 1.0 and 2.0


  • Compressible to allow for variations in cavity width
  • Breaks up and suspends mortar droppings above the flashing on two levels so weeps stay open
  • Open weave mesh construction provides hundreds of pathways for moisture to exit the cavity
  • Insect Barrier helps prevent wall damage and health hazards from insect infestations
  • Is very permeable to air, water and water vapor due to the low fiber density of the non-woven structure
  • Helps prevent efflorescence and damage from freeze-thaw cycles
  • Easy to transport, handle and cut, even on scaffolding
  • Installs easily on brick ties in multi-story cavity walls
  • Will not degrade, oxidize or react with common building materials
  • Recycled content helps with LEED certification
