Retaining walls are essential structures built to stop erosion of soil, manage water runoff, and create level terraces on sloped landscapes. If you are considering the options for retaining walls, gabions (gabiony) and traditional walls for retaining are the two most sought-after choices, each with their own advantages and disadvantages.
Gabions: An Overview
Gabions are cages made of wire that are filled with concrete, rocks or any other material. They are often used to control erosion and stabilize slopes. Gabion walls are extremely flexible and are able to adapt to different terrains. Their design permits natural drainage, reducing the pressure of water behind the wall while minimizing risk of erosion. Gabions are especially effective in areas with large water flows or soils that are unstable.
One of the key benefits of gabions is their flexibility. They are able to be easily adjusted to various shapes and sizes, making them ideal for complex terrains. Gabions also blend in well with natural surroundings due to their rock-filled appearance. This contributes to a natural appearance.
However, gabions also have some drawbacks. They may require more maintenance over time, because the wire mesh could corrode and the rock may change or settle. The process of making them involves putting every cage and filling it with rocks, which could be labor-intensive.
Traditional Retaining Walls: An Overview
Traditional retaining walls are typically made of various materials, such as concrete, brick or even stone. These walls are known for their strength and durability. Concrete retaining walls, in particular, offer a high degree of stability. They can also be modified with a variety of finishes that match aesthetic preferences. They are ideal for situations requiring a strong barrier to prevent the dumping of massive amounts of soil.
Traditional retaining walls provide an appearance that is more uniform and can be designed to withstand significant weights. They also are less prone to issues with maintenance compared to gabions. However, they usually require drainage systems that are properly designed to stop water from accumulating behind the wall, which may result in structural issues.
Comparison
In short, gabions provide flexibility and a natural integration with the landscape but may require more maintenance. Traditional retaining walls provide strength and long-lasting durability, with less maintenance but might lack the adaptability of gabions. The decision to choose between gabions or traditional retaining walls is contingent on the particular requirements for the particular project including budgetary constraints, aesthetic preferences, and environmental conditions.
