Retaining walls are building for several reasons to hold back the soil. Retaining walls made of wood, rocks, bricks or concrete can hold some level of dirt and soil away from your home, garden, and pool or play area. A retaining wall will hold back the earth falling in on your house once the hillside has been dug out to build home or other construction. Adding retaining wall will not only help you to have more usable land, but will add structure and beauty to your new area.
Retaining walls hold back land that would typically move downwards because of gravity of different structures like roads, buildings, parks, etc. Properly constructed retaining walls will act as wedge between the soil and your foundation that will preserve and even add to the ground area of your property.
Several techniques are made for constructing retaining walls ,some of them are; Cellular Confinement: They can be constructed as a gravity wall which consists of vertical layers of cells with the reinforcement installed behind the face of the wall every few layers of the cell depending on design.
Soil Nailing: It is a technique in which soil slopes, excavations or retaining walls are reinforced by the insertion of relatively slender elements, normally steel reinforcing bars.
Soil Strengthened: This type of soil strengthening, often also used without an outside wall, consists or wire mesh boxes, which are filled with roughly cut stone or other material.
