Choosing the right mortar mix for masonry (Nat)

Mortar has three primary functions:

• to provide an even bed, so that the loads on the masonry element will be distributed evenly over the whole bearing area of the bricks or blocks;
• to bond the bricks or blocks together so that they will resist the loads applied to the wall; and 
• to seal the joints and give weather-tight walls.

The mortar must be durable, sufficiently resilient to accommodate minor movements and self-healing so small cracks do not become permanent leakage paths.
