TREX website states that TREX is not suitable for ground contact. TREX is more flexible than Pressure Treated decking and often it is recommended to use 12 inch spacing versus typical 16 inch. Also, TREX has more expansion with temperature change. Have you experienced any increased flexing with the decking or any expansion problems? Were any support modifications done?

OP here... No I am not interested in a "ground contact" deck. All decking has a supporting structure called Joists. This is what the deck is connected to. This deck will sit on these joists and even they are slightly off the ground...and by ground I mean dirt. 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.
