Dimensional Terminology

Bed Depth – The nominal or approximate distance from the front face of the chopped stone to the back side of the stone.

Full bed depth – Dimension from front face of stone to back face. In dimensioned stone 4”, in chopped stone nominal 4”.

Thin veneer bed depth – nominal 1”

Thin Veneer Flats	Thin Veneer Corners

Course Height – Dimension from the bottom edge of the stone or stone course, to the top edge.

Length– Horizontal dimension of individual stone segments.

“Nominal” or "Approximate"– 1/8” to 3/4" variation in stone dimensions.

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 “Flagstone” or “Rubble”) - Irregularly broken and random sized pieces of stone set in irregular patterns.

Roughback – Outside, 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.

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

Sawn Top And Bottom - 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.

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