The Function of Wire Gabions in Preventing Landslides and Soil Erosion

Wire mesh gabions are a construction material widely used in soil stabilization, especially in areas prone to landslides or erosion. These structures are made of woven steel wire mesh shaped into a box, then filled with river stones or crushed stone. Although they may appear simple, wire mesh gabions are extremely durable and play a crucial role in maintaining land stability.

1. Resisting Soil Pressure on Slopes
Wire mesh gabions function as a retaining structure that helps maintain slope stability. By filling the gabions with heavy stones, these structures can withstand the pressure of shifting soil, especially on sloping areas or cliffs prone to landslides.

2. Preventing Erosion in Rivers and Drainage
Wire mesh gabions are often used along rivers, canals, and reservoirs. Their function is to protect riverbanks from erosion by water flow. The stone structure within the gabion absorbs the energy of the water flow, preventing the surrounding soil from eroding.

3. Strengthening Foundations in Damp and Unstable Areas
Several infrastructure projects, such as bridges, roads, and riverbank structures, use wire gabions as part of the sub-foundation. This material adds stability due to its flexible construction, which adapts to soil movement without cracking easily.

4. Remains Stable Despite Landslides
Unlike rigid concrete structures, wire gabions are flexible. When the ground experiences subsidence or small movements, the gabions can adjust their shape without losing strength. This makes them ideal for landslide-prone areas.

5. Highly Weather and Water Resistant
Gabion wire is usually coated with galvanized or PVC, making it more corrosion-resistant. With the addition of a non-perishable stone filling, gabions can last for years even when exposed to water, extreme weather, or damp soil conditions.

6. Natural Drainage System
The stone filling in gabions allows water to drain through the gaps in the rocks, preventing water buildup that can increase soil pressure. This is why gabions are more effective than concrete walls in damp areas.

7. Easy to Install and Economical
The gabion installation process is relatively quick and does not require heavy equipment. Furthermore, the filling material can be made from locally available stone, making it more cost-effective compared to other retaining structures.

Conclusion
Wire gabions are an effective, flexible, and economical solution for preventing landslides and erosion. With their high durability and natural drainage capabilities, this material is ideal for use on cliffs, riverbanks, roads, and even building foundations.
