Could possibly be caused by bad mix, Aerating additive added to lime based mortar mixes ,etc

Stages

A. Air bubbles in mortar weakening strength and durability

B. Air voids enlarge 

C. Chunks of mortar errode and fall out

D. Eventually wall becomes unstable

 Repointing should be carried out at C well before D

Check out  Cockburn Cement @Bunnings

Always read Product Information first

Need expert advice on Masonry Walls, Chimneys & Structures, eg,  reinforcemnt, cracking, dampness,etc?
