Patent ID: 8863465

Claim:
A mortarless retaining wall constructed of a plurality of segmental wall blocks stacked in an array of superimposed rows, each segmental wall block comprising: a face unit comprising a front face, a rear face opposite the front face, an upper surface, a lower surface opposite the upper surface, and one or more channels formed in the rear face, the channels extending from the upper surface to the lower surface along a face unit height, the front face being exposed and the rear face being hidden, the rear face confronting soil or granular fill being retained by the retaining wall, the upper face for supporting the lower face of a super-imposed stacked segmental wall block, the upper and lower faces resisting shear forces between adjacent segmental wall blocks, the shear forces applied by the soil or granular fill retained by the retaining wall against the segmental wall block; one or more anchoring units each comprising a first end forming a first connector, a second end forming a second connector, a central portion extending from the first end to the second end, an upper surface, and a lower surface opposite the upper surface, wherein a distance between the upper surface and the lower surface forms a height of the anchoring unit which is substantially uniform from the first end to the second end of the anchoring unit such that the upper surface abuts the lower surface of a super-imposed stacked anchoring unit, and wherein at least one of the first and second connectors is sized to slide into and be interlocked with the channels of at least one of the face units; and wherein the height of the anchoring unit is substantially one half of the face unit height such that two stacked anchoring units are of substantially equal height as the face unit.
