A construction joint is the interface between concrete placements intentionally created to facilitate construction. A cold joint is a joint or discontinuity resulting from a delay in placement of sufficient duration to preclude intermingling and bonding of the material, or where mortar or plaster rejoin or meet.
Construction Joints – These joints are placed to keep new concrete in place. They’re essentially screed rails made from wood, metal, or plastic and are placed during the pouring and finishing of concrete.
