Patio Deck Flooring Help

Q: I have a patio deck of a commercial building that I need flooring
for. The 2′ square rubber-like existing flooring has proven totally
useless as it is cupping at all four corners of each square. The
deck, which is also the roof to the floor below, consists of a layer
of Styrofoam covered with chipboard which then has sealed rubber
moisture barrier covering it. I wish to lay the flooring directly
over this rubber membrane. The deck is 13′ x 50′. I can not use
fasteners to secure anything because they would break through the
rubber deck membrane. Ideally the thickness of the flooring would be
between 1″ to 2″. Do you have any suggestions?
Thanks,
Rolande
A: Your best bet here is going to be an outdoor product which can click together. A good choice would be the snap together teak decking tiles made by Vifah. These decking slats come as either planks or as tiles and are very easy to install. Since they are meant for decking you should have no issues with moisture causing problems in the product, plus its built as a floating product so you don’t need to anchor into your membrane covered substrate.
