Hey you guys.... Tell me about putting pex into a slab. I wanna do it with the shop area of our upcoming garage/apartment project. The entire garage and shop area is 28' x 44'. The shop portion is at one end: 28' x 27'. From what I'm reading, the correct procedure is to compact the gravel base and lay out the vapor barrier. Then, cover the entire slab area with 2" foam insulation (the pink stuff). Set the wire mesh on bar chairs to keep it centered in the slab and tie the pex to the wire mesh. Set the pex run to start and stop as close as possible to the hot fluid source and form out a small area in the slab to install the manifold. Pour a slab. I'm thinking 4" thick. Thoughts? Tips?
