With almost three times the breaking strength of 3/4"thick porcelain pavers, but just 1/2" thicker, Archatrak’s ‘T30’ pavers offer a notably superior solution for constructing pedestal supported elevated decks in high traffic commercial spaces such as restaurants, bars, roof terraces, patios and other communal areas. For on-grade applications, including areas subject to vehicular traffic, these 1 1/8'' thick pavers feature impressive technical characteristics for a lightweight, large format paver, with the capability of supporting wheel loadings of over six tons. For rooftop applications, these heavy-duty pavers are the only porcelain pavers that meet the requirements of ANSI/SPRI RP-4 2013, Wind Design Standard For Ballasted Single-ply Roofing Systems which specifies that pavers installed in corner zones and perimeter zones over a fully adhered membrane must exceed 22 lb/sq.ft. A limited color range of T30 pavers are also available with inbuilt lugs on the sides which simplifies on-grade installation, guarantees accurate spacing and allows storm water to pass through. These pavers are designed to be laid on a porous open-graded aggregate base material to facilitate drainage into the subsoil.
