Segmental retaining walls consist of a facing system and a lateral tieback system. The facing systems usually consist of modular concrete blocks that interlock with each other and with the lateral restraining members. The lateral tiebacks are usually geogrids that are buried in the stable area of the backfill. In addition to supporting the wall, the geogrids also stabilize the soil behind the wall. These two factors allow higher and steeper walls to be constructed.
