Crack-A-Joint® by Danley™ – Crack inducers

InfraBuild Construction Solutions (formerly LIBERTY OneSteel Reinforcing) supplies Crack-A-Joint® by Danley™, which initiates a contraction joint in the slab when placed in wet concrete. Roll formed from a pre-galvanized strip, Crack-A-Joint® by Danley™ eliminates the need for fill as the steel edge acts as a support for the edge of the concrete, and allows easy removal of concrete slurry from the top of the joint.

Rip-A-Strip capping is available in two colours – black or grey.

Crack-A-Joint® is supplied in 3m lengths in 25mm and 250mm heights.
