Abstract
An earth fill retaining wall system that uses a removable L-shaped bracket and one or more support boards that temporarily holds the front surface of a mesh cover panel vertical aligned while backfilled with fill material. The brackets hold the mesh cover panel until tiers are stacked above. The weight of the stack tiers are used to hold the mesh cover panel on each lower tier in place. Once the above stacked tiers are formed, the brackets can be removed and reused. Attached to the lower end of the post and extending in the opposite direction of the base is an optional support shoe. A hole is formed in the shoe that receives a vertical stake or pin driven into the ground to temporarily hold the bracket in place. Attached to the post is a loop that attaches to a chain or cable used to pull the bracket forward.
