Break through Protection
Although porcelain pavers are exceptionally durable, they can nevertheless suffer damage or breakage if hard objects are dropped on the pavers from a significant height. This also includes impact from heavy glassware or bottles. With ¾” thick porcelain pavers and deck heights greater than 4”, especially in high traffic commercial installations such as bars and restaurants, self-adhesive protection sheets, steel plates or trays should be installed on the underside of the pavers.
Archatrak offers three solutions to minimize the possibility of injury should any porcelain paver suffer damage or breakage in service.
1. Shock Control 2.0 is a flexible, self-adhesive, fiberglass reinforced sheet, pre-cut to cover the underside of a 23.5″ x 23.5″ (nom.) paver. The sheet is attached to the paver by peeling off the protective backing and pressing the sheet onto the underside of a dry paver. Be aware however that Shock Control is primarily designed to hold in place pieces of any broken paver and provide temporary support only. If any paver is broken while standing on, the person must promptly move off the damaged paver as prolonged heavy weight applied to a damaged paver fitted with Shock Control 2.0 will cause it to sag and eventually fall.
2. Archatrak ‘Spansafe’ steel protection trays are constructed of 1mm thick galvanized steel sheet with ¾” high downturned edges on all four sides, folded to provide a double thickness edge for extra strength. The plates are placed with each corner resting on a pedestal head. The porcelain pavers are then laid directly over the trays and butted tightly against the tabs on the pedestals. We recommend installing a rubber shim (e.g. Archatrak ETE-LGH2) over the plates at each pedestal location, or spread a bead of silicone adhesive on the plates to minimize noise transmission and/or rattling.
3. Archatrak T30 1 1/8” thickness porcelain pavers offer considerably enhanced impact resistance compared with T20 ¾” thick pavers. Practical tests conducted by Archatrak demonstrated that full beer glasses, full wine bottles and even a 1lb. 9 oz. steel ball did not cause any damage or breakage of the T30 pavers when dropped from a height of 6’. Nevertheless, for extra security, we recommend that Shock Control sheets be fixed to the underside of T30 pavers for deck heights above 6”.
