Abstract: A modular wall block is adapted for being assembled together with a number of other blocks in stacked courses to form a retaining wall. First and second spaced apart formations are located at a rear of the block body and define therebetween a vertical fastener channel. The vertical fastener channel is adapted for receiving a complementary shaped formation of a rearwardly placed embedment block.

Abstract: A modular wall block is adapted for being assembled together with a number of other blocks in stacked courses to form a retaining wall. First and second spaced apart T-shaped formations are located at a rear of the block body, and define therebetween a T-shaped vertical fastener channel and opposing vertical side grooves. The vertical fastener channel is adapted for receiving a complementary T-shaped formation of a rearwardly placed embedment block. The vertical side grooves are adapted for cooperating with vertical side grooves of adjacent like wall blocks to selectively receive a removable wall insert.

Abstract: A modular construction block is adapted for being assembled together with a number of other blocks in stacked courses to form a wall. The construction block includes first and second opposing block faces, a top and bottom, and opposing ends. The first block face has a first plurality of vertical score lines. The second block face has a second plurality of vertical score lines. The first and second plurality of vertical score lines resemble respective mortar joints, whereby the assembled wall resembles a brick structure.
