Australian standard for retaining walls?

Retaining walls in Australia are subject to the guidelines provided by the Australian Standard AS4678. This standard delineates the recommended procedures for the design and construction of earth-retaining structures, emphasizing safety, durability, and compliance with regulatory standards. Adherence to these standards is especially critical when integrating steel into retaining walls, ensuring stability and optimal performance of the structure.

Which type of steel is recommended for a retaining wall?

Acquiring the right steel is vital for the success of your retaining wall project. The choice is influenced by factors like the planned height of the wall, the type of soil it will retain, and the environmental conditions of the site. Galvanized steel is a commonly used grade, offering specific advantages in terms of corrosion resistance, strength, and overall durability. The exceptional strength to weight ratio of high quality steel enables engineers and builders to construct structurally resilient walls that can endure significant pressure and fulfill demanding load-bearing requirements.

Enhancing your retaining wall's strength with superior steel posts.

It is crucial to obtain high-quality steel posts from reputable suppliers. Garden Supplies provides outstanding options with their 100 & 150 steel posts, recognized for their durability, corrosion resistance, and structural integrity. Customized for the requirements of retaining wall construction, these posts guarantee the long-term success and durability of your project.

Selecting the appropriate lengths for your retaining wall project.

Concrete sleeper posts are provided in a range of lengths to cater to different wall heights.
 Available: 900mm, 1200mm, 1500mm, 1800mm, 2100mm, 2400mm, 2700mm and 3000mm.

A simple way to determine the appropriate post length is by multiplying the wall height by 2. 
For example, an 800mm wall height (four concrete sleepers) would require a 1600mm length post.

However, as steel posts are supplied at standard lengths, so for this case, options like 1500mm or 1800mm would be suitable. It’s essential to consider soil properties, the load behind the wall, and the hole diameter when selecting the appropriate length.

For DIY projects, it’s advisable to opt for longer steel lengths to ensure they are securely concreted in. The key to a successful concrete sleeper retaining wall is sufficient anchoring of the UC steel posts. Taking these factors into account will ensure a stable and reliable retaining wall that stands the test of time.
