Paverdeck is a system of galvanized steel beams and panels that supports a finished surface such as tile or fieldstone. Paverdeck can be installed on concrete footings, over a concrete pad, or on helical steel piles, or be attached to the house at the ledger. Support beams are followed by steel panels, geotextile fabric, and finally by pavers, which are locked in place with polymeric sand. Paverdeck says the system is truly maintenance-free and offers flexible design options. It comes with a 30-year structural warranty. Components are manufactured from 95% recycled steel.
