Abstract
A retaining wall system is made up of standardized posts and face panels formed of a polymeric cementitious material which are reinforced by a lattice-like polymer grid embedded in the posts and panels during their formation. Similar lattice-like polymer grids are mechanically attached to the grids embedded in the panels to project horizontally from the panels and to be embedded in earth fill at one side of the wall to permanently anchor the wall in position.
