Hi all,
I'm installing drains for a shower above a concrete slab. All drain pipe to be run in wall above slab except under shower where it will be built up about 4" to accomodate drain. (cannot run drains through floor - other tennants below). I want to make a 3" hole in the slab (slab is 6" thick) to drop the p trap into to minimize the height of build up. l;m planning on using a concrete abrasive blade in circular saw and cross hatching the area and then chiseling it out. Any thoughts or recommendations before I start? I'm aware of dust and respiration issues.
Thanks in advance,
Bob
