There are times when it is necessary to create terraces to keep land from washing away in a heavy rain, so building walls has become a traditional defense against erosion. It has become an art form for those seeking beauty outdoors, and there are many materials that can contribute to making a lovely statement out of the necessity. Stones, bricks, and unique pieces of wood have all been ways to dress up the functionality of building walls to retain land in the face of nature.
While the beauty of wood pieces can be a good way to dress up landscaping, they must be fitted precisely to keep erosion at bay. For that reason alone, only the most unique pieces have been used in this capacity. Stone and brick are often used because they function better in this capacity, and their durability means less work replacing parts that might wash away in a heavy downpour.
