Retaining walls are essential for managing soil erosion, creating usable flat spaces, and adding aesthetic value to landscapes. Choosing the right material for a retaining wall is crucial to its functionality, durability, and appearance. We go over the top materials used for retaining walls, exploring their pros and cons to help you make an informed decision for your landscaping needs.
Concrete Blocks
Concrete blocks are one of the most popular choices for retaining walls due to their durability and versatility. They come in various sizes, shapes, and colours, allowing for creative and customized designs.
