Mortar

Mortar is spread on the bed and head joint surfaces of masonry units to bond the units together, and, as importantly, to keep them apart. Structurally, mortar distributes gravity loads uniformly from one unit to the next, and increases the shear strength of the assemblage. Mortar also decreases the moisture permeability of the assemblage.
