In some countries wax, petroleum-based substances or grease are used as bond breakers, but these chemicals will change characteristics of the surfaces on which they are applied. Because cracking occurs in the planes of greatest weakness, openings are particularly vulnerable. Provides effective bond breaker between casting slab and tilt-up or lift-slab panel.

TILT-CRETE has excellent stability and does not require continuous mixing throughout the application process; the material must be mixed only prior to application. An engineered method is presented in TEK 10-3 Control Joints for Concrete Masonry WallsAlternative EngineeredMethod, which is based on limiting crack width to 0.02 in. When required, control joints should be located where volume changes in the masonry due to drying shrinkage, carbonation, or temperature changes are likely to create tension in the masonry that will exceed its tensile capacity. Figure-1: This TEK focuses on non-structural cracking resulting from internal volume change of the concrete masonry.

It's purpose is to control the amount of caulking that goes into the joint, but more importantly, to "break" the 3 point "bonding" that occurs in the back of the joint and thus prevents the caulking from tearing open at this location. Price/Bag. Discover how this hybrid manufacturing process enables on-demand mold fabrication to quickly produce small batches of thermoplastic parts. 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.
