Abstract
Embodiments of the present disclosure provide a pipe collar for a drainage pipe and a mold for the pipe collar, wherein the pipe collar is formed by positioning mold walls adjacent, atop and/or around a mold face, inserting one or more safety reinforcement handlock bar elements through one or more of the walls, filling the mold with a consolidating material and removing the walls. Upon removing the walls, a formed pipe collar can be lifted, moved and otherwise manipulated using the safety reinforcement handlock bar element(s) to position the pipe collar above a drainage pipe.
