As said above, retaining walls are a great solution if you want to prevent erosion of the soil around your property. This article explains how these walls are advantageous and why they should be your choice to fight erosion. It is advisable, though, that you hire the services of professional retaining walls stonemasons so you get expert services.
Let’s take a look at how the retaining wall helps with preventing erosion:
Correcting Uneven Topography:
These walls are very useful tools in preventing erosion, which is caused by uneven topography. If you add a retaining wall, then this allows the land to be levelled, which results in reduced erosion caused by gravity, wind and rain. Retaining walls also prevent cracks and the uneven settlement of the land, which is caused by the changing weather and temperatures. The wall enables the land and the uneven areas to be cultivated and level so buildings or even other structures can be placed on top of it. Usually sand is used to fill the low areas behind the retaining wall, as it is inexpensive and easily available. These types of retaining walls are seen around beaches and coastlines and are often used to fill in or level the uneven topography before building construction.
Runoff Prevention and Drainage:
Retaining walls can be used in areas that especially see heavy rainfalls where the soil is more likely to get eroded. The walls prevent the soil from sliding or washing away, which is caused by insufficient water drainage pipes, and well organised systems to carry this water to low risk areas of land. The rainwater, through effective drainage, can be diverted to riverbeds and lakes or even dry wells. In such cases, though, the retaining wall must be fortified with concrete or even steel to make it long lasting and effective. As such, retaining walls can be used for agricultural purposes as well, where they can be installed to prevent the seepage of water from dry lands or can be used in an opposite manner where they can encourage drainage in areas that are prone to flooding.
Erosion Caused by Currents:
Retaining walls are also used to separate soil and land from moving water sources in order to prevent the erosion, which is caused by the natural marine forces. These types of retaining walls are even sometimes called “seawalls” and are very effective at reducing the impact caused by the currents and the waves on the surrounding land. The effect of moving water can easily be seen by the rock forms and the land forms caused over the years. These walls work as they form a barrier between the land and the water and thus prevent the water from washing away the soil.
