Intent

Intent 1:

To limit the probability that extruded mortar will bridge the gap between the veneer and the sheathing membrane, which could lead to the accumulation of water on the sheathing membrane, which could lead to rain penetration by capillary action, which could lead to the deterioration of elements protected by the masonry veneer, which could lead to compromised structural integrity, which could lead to harm to persons.
