I plan to pour a concrete slab for a 10x12ft shed. To try and soften the edges, I was planning on getting some standard paveing edgers as a surround to the conceret pour.
My plan for the concrete pour is to dig a suitable hole the right size and shape, surround the hole with a suitable wooden frame, put in around 5-10mm hardcord/MOT Type 1, wacker plate it down. Then put edgers around the edge; against hardcore on their bases, and the wooden frame and edge of the hold holding them upright. Then another layer of hardcore/MOT type 1, another wacker, then pour the couple of inches of concrete on top of the hardcore.
Is that acceptable way to do it? Should I instead put the edgers in with their own mortar or somthing instead?
