Retaining Wall Blocks

The best blocks for a retaining wall are interlocking concrete blocks, which are designed to fit together easily and securely without the need for mortar. They are strong and durable and can be used to create a variety of shapes and heights. Additionally, they can be filled with gravel to provide additional strength and stability.

Retaining walls are better than concrete sleepers for a few reasons. Firstly, retaining wall blocks are available in various shapes, sizes, colours and textures, allowing for more design possibilities than concrete sleepers. Blocks have an easier installation process than sleepers and only require one person to handle and install them, making the job easier. While sleepers are difficult, heavy to move, and need multiple people to handle and install them. Blocks also cost less than sleepers, so they are a more affordable option for many homeowners.
