Discover the unparalleled durability and strength of galvanised steel posts available at Concrete Sleepers Melbourne. Crafted with precision, our concrete sleeper posts play an integral part in ensuring a resilient retaining wall system, and are engineered to withstand the test of time.
FAQ's
For stability, the depth of a concrete sleeper post should be at least 1/3 the height of the wall you are constructing, plus you will need to allow an additional 100 mm for gravel drainage. For example, for a 2 m high wall, the posts should be embedded 700 mm deep, plus the gravel base.
Galvanised steel posts require a solid footing, typically made of concrete, to ensure proper support. The footing should be at least 150 mm thick and extend below the frost line to prevent shifting during freeze-thaw cycles.
Yes, steel posts can be installed in clay soils, but it's important to assess soil conditions first. In expansive soils, deeper footings may be required, or soil stabilisation may be necessary to ensure the longevity of the structure.
To ensure the retaining wall's structural integrity, the spacing between steel posts should not exceed 2.4 metres. Always refer to engineering specifications for your specific project requirements.
Steel posts are designed to support significant weight; however, the specific weight limitations depend on the size and design of the post. Consult with an engineer to determine the appropriate post for your project's load requirements.
Use a string line and a level during installation to ensure that the tops of the posts are even and form a straight line. Check the level and alignment frequently as you add each post.
Galvanised sleeper posts are low-maintenance. However, to prevent water buildup, it’s recommended they be periodically checked for signs of movement or cracking and to ensure that surrounding drainage systems are functioning correctly.
