ABSTRACT:
A construction for a retaining wall member utilizes a preformed channel in the member communicating through a slit formed between the channel and one face of the member for retention of a tieback utilized to affix the member to an underlying mass. The tieback may be retained by the mechanical interference between the walls of the slit and an enlarged portion of the tieback located within the channel. Alternatively, an interference rod may be inserted into the channel to retain the tieback.
