Patent ID: 7828497

Claim:
A method of forming a retaining wall, usable to mechanically stabilize material to be retained, comprising the steps of: a) placing in position at least one upright wall reinforcing structure wherein the at least one upright wall reinforcing structure is supported from its base; b) placing at least one retaining wall backing support in an upright position to a first side of such at least one upright wall reinforcing structure; c) wherein the at least one upright wall reinforcing structure has apertures to allow passage of at least one sprayable cementitious material to fill spaces between the upright wall reinforcing structure and the at least one retaining wall backing support; d) spraying such at least one sprayable cementitious material through the at least one upright wall reinforcing structure onto the at least one retaining wall backing support; e) wherein such spraying continues until such at least one sprayable cementitious material encases the at least one upright wall reinforcing structure; f) after such spraying is completed, selectively removing the at least one retaining wall backing support and then backfilling material to be retained against either the concrete-encased at least one upright wall reinforcing structure or the at least one retaining wall backing support.
