ag & dan, is it possible ffe is the same as top of footer ? ? ? photo suggests the floor was poured against the footer's side, NOT against the foundation wall on top of the footer,,, that might be an explanation for such a ratty/ragged const jnt.

we cut control jnts all the time w/7" circle saws & elec demo saws mounted on roller carts :thumbsup:

wire mesh only serves 2 purposes: 1, to provide conc some initial aid in resisting tension cracking; & 2, hold the broken pieces of conc together :whistling2: altho its possible some well intentioned jabonies did use wire, it could very well be at the btm of the slab,,, the only 1 who got any benefit from that is the guy who sold the mesh :laughing: wouldn't a slab-on-grade normally be a monopour/unipour ? realize those guys got paid & they're gone but i like my theory the best :yes:
