NATURAL STONE - GRANITE
Granite is a natural quarried and finished slab with a sleek modern feature because of the sleek zero-bevel edges. Granite 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 – Granite 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 –
- Concrete integrity – concrete must be in good condition, and not crumbling
- Drainage slope – concrete below must be sloped away from all buildings and structures
- Base drainage - the area below the concrete must not be subject to frost movement
- Jointing – Mortar joint recommended
ALTERNATIVE PERMEABLE BASE – Granite 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.
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 or slab 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.
