I think you are referring to a decking board glued right to the surface of say a old concrete slab. Don't know if TREX works here or not, since that is not my intention.

Question: Does anyone have any experience with TREX decking down here? I would assume in this wet and harsh climate not only the decking boards but the structure would need to be of a composite type material and not green treated.
Maybe the name of a contractor who builds ground decks with TREX?
Sorry if I misinterpreted your mention of ground deck to mean ground contact. I know what joists are since many years ago I had a building company as a side gig and built a number of decks and complete houses.
IMHO using composite material for support structure such as posts and joists with minimal clearances from soil. or sand etc. will be problematic due to high humid conditions. TREX site states that TREX decking is usually supported by pressure treated wood components. Some Lumber Co. sites recommend 18 inch spacing from deck to ground to get adequate ventilation to avoid cupping of the deck boards. Your description suggests this would not be possible.
Good luck with your project!
