In addition to the requirements of Section 5 of SCPI 1969, the following requirements shall apply to the placing of grout in engineered brick masonry:
(a) All joints or spaces designed to receive grout shall be solidly filled. The grouted longitudinal joints shall be not less than three-fourths inch wide. Mortar “fins” protruding from joints shall be removed before placing grout.
(b) When the least clear dimension of the longitudinal vertical joint or core is less than two inches, the maximum height of grout pour shall be limited to 12 inches. When the least clear dimension of the longitudinal vertical joint or core is two inches or more, the maximum height of grout pour shall not exceed 48 times the least clear dimension of the longitudinal joint or core for coarse grout nor 64 times for fine grout, but shall not exceed a height of 12 feet. Grout shall be agitated or puddled during placing to insure complete filling of the grout space.
(c) When grouting is stopped for one hour or longer the grout pour shall be stopped one and one-half inches below the top of a masonry unit. Masonry bonders (headers) shall not be used, but metal wall ties may be used to prevent spreading of the wythes and to maintain vertical alignment of the wall.
