COULD NEWTECHWOOD DECK TILES BE INSTALLED ON BARE GROUND IF LEVELED AND COVERED WITH LANDSCAPING PAPER?

This would be fine and in fact, we would recommend using the landscape paper as a weed barrier. However, you would still need to use two inches of gravel covered by one inch of sand, as a solid foundation and to allow for water runoff. The landscaping paper cannot serve as a substitute for a gravel and sand.
