ASYMMETRIC RETAINING WALL BLOCK
Document Type and Number:
WIPO Patent Application WO/2005/108693
Kind Code:
A2
Abstract:
A block suitable for use in a retaining wall, the block has a top surface, a bottom surface, a front surface, a rear surface, and opposed sides. The block includes a weakened section that extends substantially from the front to the rear surface, and which is configured and arranged to facilitate splitting the block into two smaller blocks. The weakened section can take the form of one or more slots that are generally situated within the body of the block and one or more grooves located at the front and rear surfaces, respectively. The groove at the front surface of the block is configured and arranged to simulate a joint between two adjacent blocks. Preferably, the front groove is formed by a core that modifies the block as it is removed from the mold in which it was cast. The block may include one or more projections and/or positioning elements that extend from the block in a generally vertical direction, and which are configured and arranged to engage a block in an adjacent course of blocks.
