A crib unit of heavy, rugged character and which is useable in erecting bin wall structures for various purposes such as sea walls, retaining walls, etc. The unit has a pair of spaced side walls with a connector arm extending between the side walls and joined thereto with merger segments, the merger segments being of laterally widening character to effect strengthening of the side walls to render same more resistive to bending. The crib unit when paired with a like unit encloses a bin space having a configuration which facilitates substantially uniformly distributing bin fill pressure acting against the crib unit structure defining the bin.
