Modular Concrete Sleepers is an Australian-owned and operated business specialising in the manufacturing of high-quality concrete sleepers for retaining walls, garden beds, and landscaping projects. Formerly known as Seymour Mini-Mix and Concrete Products, we rebranded in 1995 to focus on delivering durable, aesthetically pleasing, and custom-made concrete solutions. Our sleepers are crafted with precision to ensure uniformity, strength, and compliance with Australian retaining wall standards. We also supply universal steel columns, offering a complete package for both home DIY projects and large-scale commercial developments. With competitive pricing, nationwide delivery, and custom manufacturing options, we provide tailored solutions to enhance any outdoor space.
