When it comes to the landscaping process and erosion prevention, picking the correct type of retaining wall can significantly improve both functionality and aesthetics. Two popular options are gabions (gabiony) walls and traditional retaining walls. Understanding their differences will help you make an informed decision based upon your requirements.
Gabions:
Gabion walls are made of cages made of wire that are filled with stones or other substances. The main benefit is their flexibility. The mesh can be adapted to various shapes and sizes which makes gabions suitable for terrains that are uneven or irregular. They provide excellent drainage as the gaps between the rocks let water flow through, reducing the hydrostatic pressure behind the wall, and reducing erosion.
Gabion walls also have a natural, rustic appearance, blending seamlessly with the surroundings. They are fairly simple to install, requiring smaller amounts of grading work than conventional walls. In addition, they are robust and resist weathering, however, the wire mesh may become corrosive over time if properly maintained.
Traditional Retaining Walls:
Traditional retaining walls are constructed with materials such as stone, concrete or brick. These walls have an organized and formal look, which might be preferable for some landscapes. They are well-known for their durability and strength when constructed in a proper manner with appropriate footings and reinforcements. This makes them ideal for supporting large amounts of soil, or in areas with substantial elevation shifts.
However, traditional walls may be more expensive and time-consuming for installation as compared to gabions. They also require careful design to ensure drainage is properly managed, as inadequate drainage can result in pressure build-up, and potential structural failure. Maintaining the structure is another factor to consider While stone and concrete are strong, they may form cracks or require resurfacing in the course of time.
Conclusion:
Choosing between gabions and traditional retaining walls depends on your individual desires and needs. Gabions provide flexibility, ease of installation, and excellent drainage, making them suitable for natural and varied landscapes. On the other hand traditional retaining walls give structural strength and a more polished appearance, suitable for formal designs as well as large soil support. Examining factors such as cost, aesthetics, and drainage requirements will allow you to choose the most suitable option for your project.
