2. Height and Load: The height and load-bearing requirements of your wall will dictate the type and size of blocks needed. Higher walls and walls that need to support heavy loads will require more robust blocks and proper engineering.
3. Aesthetic Preferences: Consider the overall style of your landscape and choose blocks that complement your design vision. Think about colour, texture, and material to ensure a cohesive look.
4. Budget: Retaining wall blocks comes in a range of prices, so it's important to establish a budget for your project. While natural stone may be more expensive, concrete and brick blocks can offer cost-effective alternatives without sacrificing quality.
