Abstract
A retaining wall comprises a plurality of layers made from geocells. The retaining wall has a capping layer at the top of the wall, wherein the ratio of the length of the capping layer to the height of the retaining wall is at least 0.8. The retaining wall also has at least one stacking layer and may further comprise a reinforcing layer made of geogrids or, preferably, geocells. The reinforcing geocells have a height that is less than the height of the capping layer geocell.
