Treated railway sleepers used in garden projects can last anywhere from 15 to 25 years, depending on the treatment quality and exposure to the elements. With proper drainage and maintenance, they can last even longer. At Retaining Walls Auckland by LandscapingHQ, we use high-quality, treated railway sleepers to ensure longevity and resistance to rot and pests.

The typical depth-to-height ratio for a retaining wall is approximately 1:3, meaning for every foot of height, the wall should be at least one-third of that in depth. However, this can vary based on factors like soil conditions and wall materials. At Retaining Walls Auckland by LandscapingHQ, we ensure that our retaining walls are designed with the correct ratios for maximum stability and safety. Contact us for a free consultation to determine the appropriate design for your retaining wall.
To calculate the cost of a retaining wall, consider factors like the material, wall height, length, and any additional requirements such as drainage or reinforcement. Typically, costs are calculated on a per-square-metre basis, and adding labour and permit costs can give a more comprehensive estimate.
