Hello everyone. I am preparing to pour concrete (hopefully Friday the 19th) in a 40’x64’x16’wall building I constructed this year. I have 2400 ft of pex and an 8-loop manifold. Grade for the pour is at 5-6” with a larger cavity in the middle to accommodate the base for a 17’ swing jib crane. I have materials to hopefully place 3” of insulation around the edge and 3” under the first 4’ of perimeter and 2” (240-3'x4' used sheets) under the rest. I also have a roll of thin plastic 4’ wide I hope to lay out under the insulation to help as a moisture barrier. On top of the insulation I have steel livestock panels I hope to lay down and secure the pex to. then I hope to go over the top of the pex with a roll of 4' tall fencing as an additional reenforcement to the concrete.
I am open to any thoughts on this project? Most of this build is from used or gathered materials. I have been trying to read as much as possible about hydrionic slab heat and hope my ideas on this work. I just found this forum and wish I had found it a month ago. A couple things I am curious about. How close to the outer wall should the pex be to be efficient? Should the larger deep area around the jib crane be insulated the same as everything else? And could I, or should I omit pex in or around the crane? I hope to rebar this area in a heavy-duty manner. Any and all input on this project would be greatly appreciated. Thank you.
