What are the effects of the thickness of mortar bed joints (10MM &15MM) have the overall brickwork strength?
mortar bed joint thickness – in my experience – varies over the length of the course in order to offset variances in the thickness of the brick as well as to correct screw-ups from the layer. Since mortar is less solid and less stable than the brick, the thickness of the mortar bed will directly affect the stability of the wall. The thicker the joint, the less stable the structure.
