Low elevation wall construction

A retaining wall construction comprising, in combination:

• a plurality of modular blocks, each block having a generally rectangular parallelpiped configuration, said blocks arranged in courses as front blocks one upon the other to form a front wall having a front face and a back face with a generally planar contact surface defined by the back face, said blocks each being substantially identical size and construction, each of said blocks including an internal, generally vertical bore in the block between the front wall and back face to define a hollow space in the blocks, each of said blocks also including generally planar side surfaces, each of said blocks further including a slot between the bore and back face and a slot between the bore and side surfaces;
• a further plurality of said modular blocks wherein, individual blocks are positioned with a side face contact surface against the back surface of a block forming the front wall with the slots thereof aligned, said further modular blocks defining anchor blocks;
• a separate fastener positioned in aligned slots of front wall blocks and anchor blocks for retaining aligning and the side surface of said further modular blocks against the back face contact surface of the front blocks forming the retaining wall;
• and
• fill material surrounding the anchor blocks, said fill material extending into the bores of the anchor blocks.
