A retaining wall is a structure that is built to stabilize sloping ground areas, holding them in place to prevent against soil movement and erosion. This type of wall needs to be sturdy enough to hold back the soil and handle redistribution of it to other areas. Most retaining walls have holes in them to allow for the flow of rainwater and to avoid flooding. It is important to remove ground water because it reduces the pressure that the water puts on retaining walls. Retaining walls can be made from a number of materials such as stone, concrete and block. Often a retaining wall starts with a wire mesh put in place to hold back the soil for the installation of the wall.
Not all retaining walls are built the same. A retaining wall could be steps, a block or rock wall or even cement if done properly. Hiring a professional to install a retaining wall in an area before a building is erected can help to keep the flow of soil away from the building during construction. An excavator, landscaper or even engineer might construct a retaining wall depending on the scope of the project. Many retaining walls are put in place with both the aesthetic and functional opportunities in mind.
