The design and performance of most retaining walls are based on keeping the area behind the wall relatively dry. To ensure a quality project, the soils used must not become saturated during construction and the final design must route water away from the back of the wall. Incorporating berms and swales into the final design is an easy way to direct surface water away.
A retaining wall is built to provide lateral support to soil mass in order to keep it intact. These walls are rigid and serve the purpose of holding the soil at various levels. They prevent the sloping of soil. The most common need they serve is holding the soil in place between two distinct elevations. Retaining wall become a necessity in excessively sloppy areas where the soil would develop a natural tendency to slope downwards.
Retaining walls are affordable and feasible solutions to soil maintenance needs. Strong retaining wall make sure the soil on your property remains intact. Retaining wall work well along the lines of retaining the soil profile. They help you rule out the natural tendency of the soil to break loose and slide away in areas similar to a slope.
There are different types of retaining walls. The five major types of retaining walls are:
