Terraforce segmental retaining walls were developed in the late 1970s to provide a more cost-effective and versatile method of retaining steeply contoured ground than was then available using conventional construction methods. Today, a range of modular retaining wall systems competes with reinforced concrete retaining walls. Most of these segmental retaining wall systems are quicker and simpler to build with and the retaining walls more interesting and pleasing to the eye.
