The unique top tear strip is removed (during trowelling of fresh concrete) to quickly create an exact top joint shape for sealants. Bond Breaker Tape In addition, walls with adequate horizontal reinforcement may not require control joints, as the reinforcement effectively reduces the width of shrinkage cracks. However, depending on the type of facing, considerations should be given to crack control in the facing material as well. Threaded Inserts Care should be taken when constructing this type of control joint to ensure that excessive mortar is not placed in the head joint of the two control joint units, whichcan potentially lead to bonding of the two panels.

For positive bond breaking, it is essential the casting slab be 100% sealed with TILT-CRETE. Visually and physically inspect the slab to witness the entire surface has a definite sheen. Any dull spots must be recoated. Questionable areas can also be tested by dropping water on the surface. If the water beads-up or forms a bubble and does not penetrate the concrete surface, it is sealed. Any areas accepting penetration of the water must be recoated until a positive seal is achieved.
