A Graffiti Wall is a tool used in the classroom to let students share their ideas and opinions. Usually it is a piece of paper on the wall that students can write answers to a question on.
Gravity walls depend on their mass(stone, concrete or other heavy material) to resist pressure from behind and may have a 'batter' setback to improve stability by leaning back toward the retained soil. For short landscaping walls, they are often made from mortarless stone or segmental concrete units (masonry units).
