Abstract
A system and a method for sawing control joints in concrete barriers is provided. The system includes a barrier mounting frame slidably mountable about the barrier, on the top, first and second lateral faces of the barrier. The system also includes a saw attachment having a circular saw attached thereto, the circular saw being manually operable. A linkage assembly connects the frame mounting barrier to the saw attachment, and allows to manually move the circular saw up or down, and towards or away from the barrier, when in use, to create the control joint transversally along the top, first and second lateral faces of the barrier.
