toothing

Brickwork awaiting extension

Toothing refers to bricks or stones left projecting from a wall so that future construction can be bonded to it, creating a strong connection between old and new masonry.

The term also describes the process of creating such projections, or the interlocking pattern they form.

In woodworking and machinery, toothing can refer to the arrangement of teeth on a gear, saw blade, or similar tool.

The toothing on the old wall showed where an addition had been planned but never built.
