ABSTRACT:
A surface expansion device that enables an area subject to vertical and/or horizontal expansion and contraction to continue to be passable with minimum disturbance to the adjacent surface areas. The device causes the entire surface subject to expansion to be elevated or elongated at a uniform rate. A series of break-off or collapsible tabs in each of several segments causes uniform movement of each of the several segments.
