Abstract: A retaining wall block that includes three textured outer face surfaces and can be divided into a pair of sub-blocks of different sizes that are configured to be compatible with each other for use in the construction of a retaining wall having a random appearance. The retaining wall block has three textured outer face surfaces of varying lengths and when the retaining wall block is separated into its sub-blocks, each of the sub-blocks define two additional textured face surfaces of different lengths. The main retaining wall block is capable of creating individual wall blocks having one of six different face surface lengths.

Abstract: A masonry system including three types of different individual masonry blocks that can be stacked to form recessed horizontal and vertical belts in a wall formed from the masonry blocks. The masonry system includes a horizontal block having a decorative band extending horizontally along a front face surface of the horizontal block. The horizontal decorative band is recessed from the front face surface. The masonry system further includes a vertical block having a decorative band extending vertically in the front face surface of the vertical block. The vertical decorative band is recessed from the front face surface. The masonry system further includes an intersect block having both a horizontal decorative band and a vertical decorative band joined to each other. The intersect block can be positioned to provide the required transition between horizontal and vertical belts formed in a wall assembled by using the masonry system of the present invention.

Abstract: A structural block useful in constructing a wall for absorbing sound. The structural block includes a pair of internal cavities which are separated by a center wall. A pair of angled front walls are positioned along the front surface of the structural block. The block further includes a pair of acoustical openings. The first acoustical opening is located in the center wall, while the second acoustical opening is located in one of the end walls. Each of the pair of acoustical openings provides a path for sound to travel from the exterior of the structural block into the pair of internal cavities, where the sound is dampened. Preferably, the structural block contains a pair of retaining grooves on each of the end walls and on each side of the side wall to retain a sound attenuator which can be positioned within each of the internal cavities.
