Stone Veneer

Stone veneer simulates full depth, load-bearing stone construction. The veneer configuration allows installation of water proof membranes, flashings and insulation behind the stone, which otherwise would not be possible.

Stone Types

The type of stone used will be determined by cost, availability, appearance, durability and ease of fabrication (related to cost). Granite, for example, is a much harder stone and therefore more difficult to shape and fabricate than limestone or sandstone, which will affect cost in terms of labor.

Many types of prefabricated or cast stone are available that simulate real stone but are fabricated in modular or near modular sizes and shapes to expedite construction. Manufactured stone will generally be less durable both because the material is typically less dense and because the units may not be as deep, so that the veneer will not be as massive and therefore stable.

Stone Veneer Installation Patterns

Stone veneer can be installed in various patterns. Ashlar patterns are composed of rectangular units having sawed or squared bed surfaces and bonded by mortar. Rubble patterns are composed of irregular-shaped units bonded by mortar.

Stone Anchorage, Code Requirements

Codes covering anchored and adhered stone veneers are covered under the same section as those for manufactured modular masonry and specified in chapter 6 of the Building Code Requirements and Specification for Masonry Structures reported by the Masonry Standards Joint Committee (MSJC).

Construction Issues

The non-modular and uneven characteristics of natural stone create challenges for the installer including uneven coursing and differing unit depths. Uneven bedding surfaces must be compensated for with varying thicknesses of mortar application. Natural cleavage lines can result in cracking or fracture of stone units.
