Similar to concrete masonry veneers, half high concrete masonry unit assemblies are installed with a larger percentage of mortar, which in turn has a larger potential for system shrinkage and therefore cracking potential. TILT-CRETE may be applied with a commercial hand sprayer, such as a Chapin 1949. Additionally, since foundation walls are subjected to relatively constant temperature and moisture conditions, shrinkage cracking in below grade walls tends to be less significant than in above grade walls. See TEK 19-6A, Joint Sealants for Concrete Masonry Walls (ref. Always verify the presence of a uniform bond-breaker coat as indicated by a dry, soap-like feel prior to placing panel concrete. Crack Control for Concrete Brick and Other Concrete Masonry Veneers. Shear transfer devices such as preformed gaskets or shear keys (such as those shown in Figures 3a, 3d, 3e, 3f, 3h and 3i) may not be necessary when using openings wrapped with reinforcement in wall segments designed to resist the lateral loads applied directly to them plus those transferred from the opening enclosure.
