Specialist in Sleeper Retaining Walls

Concrete Sleeper Retaining Walls
Strong, sleek, and low-maintenance — concrete sleeper retaining walls resist rot, termites, and weather while adding a modern finish. A durable choice for both homes and commercial sites.

Composite Sleeper Retaining Walls
Affordable, stylish, and built to last — composite sleeper retaining walls come with a 35-year warranty and can stand strong for over 100 years. Available in colours and styles to match any home.

Colour bond fencing
Colorbond fencing is a durable, low-maintenance steel fencing solution known for its strength, clean appearance, and long lifespan. Made from pre-painted steel, it resists rust, fire, and termites while offering excellent privacy and security.
Available in a wide range of colours and styles, Colorbond fencing suits both residential and commercial properties, providing a modern, attractive boundary that requires little upkeep compared to timber or traditional fencing options
Fence brackets
Galvanised steel fence brackets provide a strong, durable, and rust-resistant solution for installing fences without the need to dig holes. These brackets are designed to securely attach fence posts to retaining walls, concrete slabs, or existing structures, creating a clean and efficient installation process.
By fixing posts directly to solid surfaces, they allow for a true zero boundary line, maximising property space and ensuring a neat, professional finish. The galvanised coating protects against corrosion, making them ideal for long-term outdoor use with minimal maintenance.
