How Do Gabions Last and What Influences Their Durability?

Many landscaping and construction projects now prominently feature gabion baskets. If you encounter a pile of rocks or other materials held in place by wire mesh, you’re likely looking at a gabion. Built to serve various purposes, such as retaining walls, landscape beautification, and erosion control, gabions are versatile. But just how long do gabion retaining walls last?

This article explores the various factors that influence the longevity of gabions and provides insights on how to ensure their longevity.

How Long Do Gabion Structures Last?

If you are wondering how long gabion structures last, the shortest answer is that a gabion structure can last anywhere between 20 to 120 years. The wide difference in the years that a gabion structure can last depends on several factors, including:

• Expert Installation: Your gabion will last longer if you choose experts to do the installation. Expert installation includes a strong and stable foundation and proper backfill material that only professional gabion builders understand. The expert installation uses techniques that also prevent bulging, settling, and other structural issues that often reduce the gabion’s lifespan.
• Prevailing Environmental Conditions: Another factor that determines how long gabions last is the conditions of the environment in which the gabion basket is placed. If your gabion basket exists in an environment defined by frost, heavy rains, and prolonged hours of sunlight, then it will deteriorate faster. You can improve the gabion’s lifespan in such conditions by ensuring proper installation and maintenance to mitigate the inevitable impacts of these environmental conditions.
• Regularity in Maintenance: Gabions should not be left to the elements, and routine maintenance is essential to extend their lifespan. Regular maintenance duties include checking for any signs of bulging, shifting, or soil erosion and finding ways to address those issues before they completely destroy the gabion. 
• The Quality of Materials Used: If you build your gabion using quality materials, it will definitely last longer. The materials in question include quality wire mesh made with galvanized steel or PVC-coated wire. The wire mesh made using these materials is particularly resistant to corrosion, which is impossible with lower-quality materials that degrade faster. Corrosion caused by the elements degrades a gabion faster, shortening its lifespan.
