Abstract
Disclosed herein are embodiments of a retaining wall system, as well as embodiments of blocks and other devices for use in a retaining wall system. In some embodiments, a retaining wall includes a plurality of face blocks and a plurality of trunk blocks arranged in a plurality of courses of blocks. In some embodiments, a face block can include a face portion and a pair of leg portions, and each of the leg portions can be adapted to be coupled to a trunk block. In some embodiments, various block connecting devices can be used to connect blocks in a single course of blocks and various block alignment devices can be used to align blocks in adjacent courses.

A wall block assembly comprising:
- a face block comprising a face portion and first and second leg portions formed integrally with the face portion, the face portion and the first and second leg portions comprise a one-piece, seamless construction, wherein each leg portion extends away from the face portion to a rear portion of the leg portion, the rear portion of each leg portion defining a rear surface at the rearmost end of the leg portion;
- and
- a trunk block comprising first and second end portions and an intermediate portion which interconnects the first and second end portions, wherein the first end portion is connected to the rear portion of the first leg portion such that the first end portion of the trunk block is held against the rear surface of the first leg portion and the second end portion is connected to the rear portion of the second leg portion such that the second end portion of the trunk block is held against the rear surface of the second leg portion, and wherein the face portion, first leg portion, second leg portion, and the trunk block define an enclosed space in a horizontal plane to receive backfill material;
- wherein the face block and the trunk block are separate components that are not casted to each other;
- a first connecting element connecting the rear portion of the first leg portion of the face block to the first end portion of the trunk block, wherein the first connecting element is a separate component from the face block and the trunk block.
