Can I install without screws? I have a porch with a wall on two sides that I can't screw into. Also, do I need a drainage gap underneath?

Yes, the NewTechWood UltraShield 12" x 12" Deck Tiles do not require screwing into the wall. This is one of the simplest products to install. The tiles have a locking system making it easy to interlock them onto one another. A drainage gap is not always needed. Most of our customers simply lay these down over a flat surface and interlock them together.
