The retaining wall is made of packed tires stacked in a running-bond pattern to maximize interlocking between courses. Tires are filled with the earth taken out during the excavation stage, and non-biodegradable waste. There is a batter of 4” between each course of tires and the wall has a total height of 15.5’.
The space between the undisturbed soil and the tires is filled with sand. In order to drain, water goes through the sand before reaching a gravel trench at the bottom of the wall. A concrete drain tile lays in the trench and is connected to perpendicular tiles crossing the wall at a regular spacing.
