Expansion joint holder and a method of pouring concrete sections

Abstract

The invention provides a concrete section expansion joint holder that holds an expansion joint such that the resulting joint is straight, wherein the holder does not need to be removed either during or after the pouring of the concrete, thereby allowing more efficient pouring of concrete over large layout surfaces. Also provided is method of pouring concrete using the expansion joint holder. The present invention is used in the construction industry to create concrete sidewalks and roads.
