Garage floor moisture barrier

| Posted in General Questions on
Hello – I plan to turn existing garage into living space. It is a concrete slab. I’d like to build floor up with 2 x 8’s. and eventually install electric radiant floor heat.
Could you help with proper direction as to how to create moisture barrier?

It can be as simple as putting down plastic sheeting and then putting your 2x8 sleepers on that. But without a more detailed look at your specific garage it's hard to give a one size fits all answer.
These help?

Lstiburek is adamant about not putting plastic sheet on concrete (because of mold risk). A fully adhered coating is better.
