BASF’s ZERO-C Concrete Repair Technology, a line of cementitious repair mortars that exhibit no cracking when tested in accordance with ASTM C1581. It’s the first concrete repair material formulated and proven to eliminate material cracking. In addition to crack resistance, ZERO-C’s patent pending mix-and-match material design brings simplicity to the job site. A single base mortar can be modified by using different liquids to change the material consistency as project demands change, reducing the number of materials that have to be stored on the job site.
