What’s the Use for Retaining Walls?

Retaining walls are usually built to retain soil runoff and provide a barrier against erosion. As a result, these structures are used for a variety of purposes around the world. They are constructed in different sizes and shapes and may be built as wall-mounted retaining walls or free-standing retaining walls. Retaining walls are used for residential as well as commercial properties. Retaining walls are essential in constructing any structure.

Retaining walls are also used for various landscaping functions, including flower bed landscaping, garden walls, and retaining walls to cover patios, decks, and walkways. In addition, retaining wall systems help in retaining soil in landscapes. Since these are used to retain soil, they are most commonly used in agricultural landscapes.

One of the significant benefits of building retaining walls is the prevention of soil erosion. Erosion occurs when soil is lifted by eroding the underlying surface. It causes land areas to erode to one side, sometimes causing severe damage to the landscape and property value by preventing this soil erosion, retaining walls to reduce the amount of lost soil and allow landscapes to remain intact and undamaged.

In addition to acting as a prevention mechanism for soil erosion, retaining walls also provide a level of security against natural weather events such as hurricanes, tornadoes and strong winds. These structures usually provide a greater security level than free-standing structures because gravity walls are typically constructed with a core of concrete and two sides of wood grafted to the core. The core serves as a layer of protection for the exterior surfaces and a frame anchored to the underlying soil.

Gravity drainage is often used in retaining walls in Adelaide to reduce flood risk for residential landscapes. When water is retained in the structure instead of being absorbed into the earth’s surface, the structure is said to “sit up” and drain any water associated with standing water downstream. The structure may comprise permeable or waterproof materials and can be installed in either open or enclosed forms. Permeable material retaining walls allow water to percolate through the walls, while waterproof materials prevent water from percolating through the structure.

To create a more visually appealing landscape, homeowners may incorporate retaining walls into their overall yard plan. A well-designed wall will add visual continuity and character to a yard while also reducing the amount of maintenance required for a yard with no wall. An adequately designed wall will enhance a yard’s landscape and landscaping while also lowering the cost of gardening and landscaping on a piece of property. Properly designed and built, retaining walls can make an otherwise unattractive yard a lot more attractive.


Because of their potential impact on the environment, many landowners are now building retaining walls built with long-lasting materials impervious to natural elements such as wind and water. Such structures are generally constructed out of concrete, and other concretes resistant to natural and artificial erosion. Typically, these walls are built on steep slopes that are more susceptible to washouts. When soil is washed away from the slopes during high winds, it will typically empty into lower areas until it reaches a point where it becomes too wet to support plant life. A properly constructed retaining wall is designed to withstand high winds and tides, and in doing so, it effectively holds back eroding slopes.

Another beneficial aspect of concrete retaining walls in Adelaide is the fact that they require little to no maintenance. Once they are built and set into place, they will require very little maintenance, if any. In terms of soil erosion, most concrete walls are built with a layer of gypsum granules that act as a brake, allowing the wall to retain its shape and prevent soil from washing away. In addition, unlike wooden or asphalt outdoor retaining walls, concrete does not tend to warp or grow warmer than the surrounding soil. It makes concrete an ideal material to use for both interior and exterior walls.
