Actually, I believe, especially in scenario of radiant ground installation, that it's a lot easier and safer to put it beneath the foam, and with new procedures about radon and also other soil fuel barrier, You must protect this poly from concrete contractors hooks ( the one they use to elevate the mesh).
It would not take place continuously, even so the instances I've witnessed it materialize it had been very little fewer than a horror clearly show. I just won't choose that danger.

So, to reply the issue, Sure, using the blotter sand strategy was unsafe and illogic but putting the poly up or down can be a issue of work site affliction, that is it.
We set the ploy between 2 layers of EPS. With the very first layer down, it is a snap to tape the seams with a top quality tape. The 2nd layer of EPS protects the poly in the course of the pour and retains if from having punctured from possibly facet.
