So, we screwed 2”x4” onto the concrete block wall as a ledger. Then we cut 3/4” plywood and set it on the 2”x4” ledger and screwed it down. We propped up the other side on the plywood with 2”x and 4”x4”. Then we placed plastic landscape edging on the plywood and screwed it in place from the bottom of the plywood up into the edging. Then we sprayed adhesive onto the inside of the edging and pulled fiberglass insulation apart and adhered it to the edging. Once adhered, we poured the concrete and pressed it against the insulation as we poured it. The photo shows it right before applying the adhesive and fiberglass.Oh sure, I understand. Thanks. So I'm guessing you had a wooden frame/form for the countertop and you simply lined the inside of the form with a strip of insulation? I really like the end result!
