What action must be taken if mortar projects into the grout space?

If mortar projects into the grout space, removing it before inspection is necessary to ensure proper bonding and functionality of the grout. Mortar protruding into the grout space can interfere with the grout's ability to fill the joints properly, potentially leading to inadequate strength and durability. Allowing mortar to remain can create voids or weak points in the structure, as the grout needs a clear space to penetrate and form a solid bond with the masonry units. This practice promotes compliance with building standards and ensures quality workmanship, critical for the integrity of the overall construction. Proper cleaning and preparation of the grout space prior to grouting helps achieve a strong and effective joint between masonry elements.
