I have a contractor who insists he wants to bury PVC directly in a slab. I know this is wrong... the concrete makes both PVC pipe and cement at fittings brittle, and they fail with the slightest expansion or contraction. I have looked everywhere on the web for a reference to substantiate this, but I can find nothing. Can someone please refer me to such a reference? This is a HUGE issue on this project. Thanks!
