The life cycle of a retaining wall is dependent on its material, the environment, climate and exposure to elements. Timber sleeper or treated timber solutions have an expectancy of 20-30 years. Brick masonry and concrete retaining walls are expected to last up to 50-100 years depending on the quality. Any wall system with galvanised steel uprights are expected to last much longer, but are more expensive.
Here at Ferguson Landscape & Design, our retaining walls are constructed with minimal need for ongoing maintenance given we only select and build the most suitable retaining walls based on these factors.
