SuperPost is a lightweight composite post that holds your retaining wall together. It’s easy to install, won’t rust or rot, and gives strong vertical support, making it perfect for gardeners, DIYers and landscapers alike.

SuperPost is a sturdy, weather-resistant composite post made from fibre-reinforced polymer (FRP). It comes in two shapes:

• H‑Post (H‑shaped): used between sleepers for walls up to ~1 m high.
  

• C‑Post (C‑shaped): used at ends or corners, same wall height range.
  

At around 2.4 m long and weighing just ~6 kg, SuperPost is much lighter and easier to handle than concrete or steel alternatives. You just dig or drill a hole, stand the post up, slide your composite sleepers into its built-in channel and wedge them securely in place.

SuperPost is built to last – no rust, no rot, UV-stable and engineered to meet Australian structural standards. It works seamlessly with the SuperSleeper system for an easy-to-install, long-lasting wall.
