Any paver laid without adhesives or other hold down devices on a rooftop, balcony or other exposed area, will be subject to the force of wind, with the risk in some cases of the pavers becoming airborne. It is very important when designing decks on rooftops with pedestal supported pavers, to give adequate consideration to the potential for wind uplift. Large-scale wind tunnel research studies have shown that the most effective means of mitigating wind uplift is to lock the pavers together as one rigid body. Archatrak has developed two systems to lock pedestal supported porcelain pavers together in an array to reduce the risk of wind uplift, using either 2cm or 3cm thick pavers. Neither system affects the visual appearance of the deck and both systems can be used where a totally non-combustible deck is needed.
