ABSTRACT:
An expansion joint for settable compositions such as concrete and the like comprises a base portion which is embedded in the composition before it sets with its upper surface adjacent the surface of the composition, and a cover portion which is engagingly received in a slot defined by the removal of a portion of the upper surface of the base portion after the composition hardens around the base. The cover portion is sufficiently wide to cover gaps in the composition adjacent the edge of the base portion. Two or more base portions may be secured together to provide an expansion joint to variable depths in the composition.
