A brick-on-sand patio was added to the house back in the 1970s atop a poured concrete foundation that goes down 36", below frost-depth, per local code. A brick-veneer was adhered with mortar to the outer wall of the concrete slab.
That veneer had no foundation beneath it, and so, with the passing years, the veneer has peeled away from the slab. With nothing to hold the outer pavers in place, they too have worked themselves loose. Prior owners tried the temporary fix of putting some mortar between the bricks, but that has cracked and they've worked loose. The outer edges of the concrete slab have begun to crumble.
I could use a demolition chisel to remove the paver layer pretty easily and then clean off the sand and power-wash everything. But how to repair the crumbling edge of the concrete slab so that it has a nice clean edge that will hold up over time?
To repair the corner, should diamond metal mesh with a 90-degree bend be pinned to the face of the slab using a concrete pin gun and then a layer of cement applied to the mesh, to shape a new 90-degree cement edge?
