Retaining walls are generally relatively solid walls used primarily for supporting soil along the two sides of a retaining pond or lake, so it can then be retained at different levels in the ground. In most cases these walls will be made of concrete and are built to a certain height, which depends largely on the size and shape of the pond. There are several different kinds of materials that can be used to build retaining walls, but concrete is the most common. The actual size of the wall will depend on the amount of space available and also the amount of ground it can hold. More information

Where Is The Best The Uses Of Retaining Walls?

Construction of a retaining wall generally follows two methods, either the inside or the outside approach. Inside approaches require digging around the perimeter of the wall to expose the soil beneath it, usually with the assistance of a backhoe or similar digging machine. The digger is then inserted into the excavated area and secured by a frame. A series of stakes are placed on either side of the wall and trenches are then created within them, providing a place for the digging of the concrete. A series of cuttings or channels are then laid within the trench, leading down to an exit point at the bottom of the wall.

An external approach to building a retaining wall is through the use of a full-length, straight reinforced wall, which is supported at the top by heavy concrete foundations. It can take several days to apply the concrete and once it is in place, it must be allowed to cure before any further work can begin, which may include the leveling of the topography by hand or with a ballast tool. After the topography has been leveled, a set of steps, known as a gravity wall, can be constructed to place the wall against the downhill slope. This type of retaining wall needs fewer cutting corners, because the materials required are not as costly as those required by an internal system, which may include earth, concrete, gravel and steel posts.
