NATURAL STONE - SANDSTONE
Sandstone is a natural quarried and finished slab with a sleek modern feature because of the sleek zero-bevel edges. Sandstone is used residentially or commercially. Sandstone can also be used in commercial roof deck pedestal applications where a thinner module is required.
Installation Manual – For complete installation information, download the manual here.
Over Concrete Installation – 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” of ¾” crusher run gravel under the pad for support and drainage, (use any road base gravel in accordance with ASTM-D2940) compacted to 98% Standard Proctor Density (SPD).
Special Notes: Concrete Direct Overlay –
Alternative Permeable Base – Sandstone may also be installed on a permeable base.
Min. 6” – 8” of ¾“ clear open-graded stone compacted to achieve full particle lock-up and consolidation. (Clear open-graded does not compact but does consolidate slightly by rattling the particles together.)
Alternative Permeable Bedding Course – 1” thick of 1/8” 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.
- When installing over a permeable base, you only need to apply the slurry coat to the back of the sandstone.
Handling – Exercise caution when handling this product, as contact between its zero-bevel edges may cause damage.
Edge Restraint - 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.
