Limestone is a thinly quarried slab with sharp zero-bevel edges. Limestone can be used residentially or commercially, but is not suitable for any vehicular applications. Porcelain can also be used in commercial roof deck pedestal applications where a thinner/lighter module is specified. Consult the project engineer for specific installation instructions for roof deck applications.
OVER CONCRETE INSTALLATION – Limestone slabs 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 – Masonry mortar.
HANDLING – Exercise caution when handling this product, as contact between its zero-bevel edges may cause damage.
EDGE RESTRAINT – not required when installed over concrete. Use manufacturer’s edge restraint system for high density foam installation.
CLEANERS – Limestone slabs clean with simple soap and water. If the stains are more persistent, only use Uni-Care Stone cleaning products. Unicare Products
