<p>The present invention is a block having an elongated and hexagonal shape. A central void runs through the block. The block is formed of an elastomeric and water-repellant material. The hexagonal shape facilitates stacking of blocks having identical hexagon dimensions, although the elongated dimension, or length, of the blocks may be different. The central void of the block may be filled with one or more materials that impart additional characteristics to the block and the resulting structure.</p> |
