pouring a slab over radiant heating
pouring a slab over radiant heating
(OP)
A slab will be poured soon in the basement of our two story addition. We have 2" foam insulation under and at edges,and vapor barrier. Then a steel grid is laid to which the radiant heat pipe is attached. We want a nice smooth finish. Any suggestions and/ or cautions. The structure is enclosed.
Thanks

1. Be sure the subgrade has been properly compacted
2. Pressure test the heat piping BEFORE you concrete.
3. Be sure the heat pipe is acceptable for use in a concrete slab. I know of project that used black iron piping that eventually started leaking after reacting in the concrete. They never could find all the leaks.
4. Be sure to provide a method, other than saw cutting, to provide crack control joints in the slab.
Good luck!

A few thoughts:
1. For the joints you could use the PVC "zip-strips".
2. I do think you are better of using a SoftCut saw. The main thing is to KNOW where the pipes are, make sure that they are held below the level of the saw cut.
