Mortar Break® DT logo

Mortar Break® DT is our multi-level mortar deflection system for cavity wall construction that breaks up mortar on four different levels. Our design gives specifiers and contractors more options from one manufacturing source.

For use at all cavity wall flashing locations. The molded polymer core geomatrix design allows moisture to seep down through any mortar droppings and weep out of the wall through mortar free weep vents. Mortar Break® DT used with properly installed flashing and weep vents, along with good mortar applying techniques, will ensure the performance of a well-designed masonry wall.
