Thin veneer bed depth – nominal 1”

Thin Veneer Flats
Thin Veneer Corners

Stone Patterns and Face Finishes

Dimensional Stone - Natural building stone that has been sawn or machined on all sides to specific shapes and/or sizes.

Random Builders Stone (sometimes called “rubble” or “flagstone”) - Irregularly broken and random sized pieces of stone, set in irregular patterns.

Quarry Chopped, Snapped Edge (Uncoursed) – Stone is split/chopped at top and bottom beds and at approximate right angles at the ends.

Sawn Top And Bottom (Uncoursed or Coursed) - Sawed at the top and bottom beds and the ends are split/chopped either by hand or by machine at approximate right angles to the top and bottom surface.

Roughback - Outside, natural, exposed surface of a quarry block, having one side sawn and the opposing side natural or rough. The natural face of the stone has a wider range of colors due to weathering (See Stone Types and Colors).

Split-faced - The face surface area of individual modules is chopped to give a rough textured finish.
