The concept of stabilized earth structures has been around for centuries. Historically, grass mats, straw, and branches have been used to stabilize soil. Now, soil reinforcement utilizes technologically advanced geosynthetic materials to secure earth in retaining walls, bridge abutments, and many other applications. This course reviews the basic concepts about segmental retaining wall systems, focusing on geogrid reinforcement applications, site conditions, and the construction sequence. Key success factors are also discussed.
