Abstract

Retention of earthen formations and the provision of a retaining wall block system that utilizes one size and shaped block that can be multi-oriented to create random wall patterns while maintaining connection with the reinforcing sheet material as known in traditional block wall systems. Multi-oriented segmental wall blocks, soil reinforcing system, and methods related thereto are disclosed. The wall block may be a concrete masonry block used for constructing retaining walls. The wall block may include a front face; a rear cavity opposing the front face and formed by an inner rear face, an outer rear face on three sides of the inner rear face and spaced apart therefrom, and a shelf defined therein by the inner rear face and the outer rear face; a troughed top face residing between the front face and the outer rear face; a flat bottom face opposing the troughed top face; a first side face residing between the front face and the outer rear face, and between the troughed top face and the flat bottom face; a second side face opposing the first side face; a trough running along the length of the troughed top face and along the length of the first side face; a first groove disposed within the trough and running along the length of the troughed top face and along the length of the first side face; and a second groove running along the length of the second side face. The “behind the face” grooves may receive mechanical connectors for simple connection to adjacent wall blocks and/or other soil reinforcing elements. A soil reinforcing system is provided that includes arrangements of horizontally and/or vertically oriented wall blocks and/or other soil reinforcing elements that may all couple together via mechanical connectors.
