Bond breaker tape is black polypropylene tape that provides an option to break the bond of the sealant between the joints between the surfaces of the concrete. This type of bond breaker is opposite to that of the previous one. To prevent that for precast slabs, membrane-forming bond breakers are applied so that it can hold up the water, necessary for the chemical reaction. TILT-CRETE is used as a cure and bond-breaker in tilt-up, lift-slab, and precast concrete construction. It prevents cracks in the concrete slab due to variations in temperature and humidity. Bond breakers are usually designed for curing compounds to slab and precast members. Joint sealant should be designed and constructed to allow free extension and compression during the opening and closure of joints. These bond breakers have the property to hold the water in the casting slab. Infrastructure / Concrete Expansion Joints Video. Legal Notices / Imprint Concrete Primers, Releases and Bond Breakers.
