Concrete Sleepers

Concrete Sleepers are strong and durable retaining wall materials that are sure to make your walls sturdy for a long time. These blocks are ideal for vertical boundary walls and retainer walls as they are impervious to insects and are remarkably resistant to rotting, splitting, splintering, and warping.

Available in a wide variety of colours, patterns, and textures, so you’ll never have issues blending it in with the current design of your home or the layout of your property!
