The answer to 'how often to retaining wall installation' is that retaining walls typically need to be inspected and maintained every 1-2 years. Proper installation and ongoing care is essential to ensure the long-term stability and safety of a retaining wall. Regular inspections can help identify any potential issues, such as cracks, shifting, or drainage problems, before they become major structural concerns.
Homeowners should visually inspect their retaining wall at least once a year, looking for signs of wear or damage. Every 2-3 years, it's recommended to have a professional landscaper or engineer assess the wall to ensure it is still functioning as intended. Depending on the material, age, and environmental factors, some retaining walls may need more frequent maintenance or even partial reconstruction after 10-15 years.
