This consists of vertical walls that don’t slope towards the included earth, along with walls greater than three feet. Depending on the height of the wall and the pressure of the earth behind it, the additional assistances might be in the type of buried footings, steel reinforcement, cantilevered style, or tie-backs that extend deep into the earth behind the wall and link to buried anchors called “dead men.” You could also add extra strength with a “gravity wall,” which is so broad that its weight works as a strengthen against the pressure of the soil behind it.
