| Details for Retaining Wall Plans
 Free Retaining Wall plans - A retaining wall holds back earth materials such as rock, sand, dirt and even water, and keeps them in place to prevent erosion or displacement. Retaining walls are usually made of stone, brick, vinyl, steel, metal, concrete, or wood. Railroad ties have been used, but not anymore due to environmental concerns. While one-piece concrete or wood walls used to be most popular, segmental walls are used more often because they are cheaper, easier and more environmentally friendly. The most important thing to remember when building a retaining wall is the lateral earth pressure - it should be the smallest at the top because the wall could move and be ineffective otehrwise.
