Key Features

• Sandstone must be installed on a stable base, the best way to achieve this is to mortar the units on to a poured concrete pad - preferably a new concrete pad, although existing concrete can be used, it is recommended that you have a minimum 4 in. of 3/4 in. crusher run gravel under the pad for support and drainage, compacted to 98% Standard Proctor Density (SPD)
• Sandstone may also be installed on a permeable base
• Minimum 6 to 8 in. of 3/4 in. clear open-graded stone compacted to achieve full particle lock up and consolidation
• 1 in. thick of 1/8 in. clear open-graded chip stone - (ASTM No. 8 or 9) screeded over base
• When installing over a concrete pad, waterproofing the sandstone and the concrete pad is an important procedure to prevent discoloration of the sandstone, a bond/slurry-coat should be brushed onto the concrete pad prior to applying the mortar bedding, apply the same bond-coat to the backs of each sandstone unit before placing
• Exercise caution when handling this product, as contact between its zero bevel edges may cause damage, larger units should be placed mechanically with a vacuum lifter
• Always install an edge restraint around the perimeter of any paver installation not restrained by building structures, "spike in" edge restraints come in plastic and various metals and work well for most applications, a concrete curb or a "sub surface concrete wedge" can also be installed to retain the edge
