Abstract
A system for protecting and draining expansion joints joining juxtaposed discrete sections of construction materials is disclosed in which a pair of laterally disposed sheet members having free ends rebent into moveably interlocked curves, and secured ends fixed to the construction material sections cooperate to form a liquid collector between the sections of construction materials such that compensation for changes in the width of the gap is accomplished by relative movement of the interlocked curves. A cover member spans the joint above the sheet members.
