Expansion Joint

A space left around the perimeter of the room or between sections of flooring that allows for the movement and expansion of the flooring.

Expansion Spacing

Spaces placed between every two or three feet of flooring to allow it to expand and contract with changes to humidity and temperature.

Expansion Voids

Areas where no flooring or subfloor is installed to provide space for movement.

Exposed Aggregate

Colored rocks or other aggregate exposed on the surface of concrete, generally by using abrasive materials or a pressure washer to remove the surface mortar. It is also seen on the surface of natural stone flooring.
