The 20 kg Cempost Postcrete Fast-Setting Concrete is a premium ready-mixed solution designed to make post installation faster, cleaner and more reliable. If you’re erecting fence posts, gate posts, signage, rotary clothes‐dryers or any vertical posts in your garden or yard, this product is engineered to simplify the job — no sand, no separate cement, no labourious mixing.

Each bag contains 20 kg bags of high-strength postcrete. The pre-blended formula means you simply pour the dry mix into your posthole, add the recommended amount of water, and allow it to begin setting. There’s minimal fuss, minimal mixing, and you avoid the risk of incorrect mixing ratios. Because it begins to set in as little as 5 to 10 minutes, your post is secured quickly and you can carry on with subsequent work without long delays.

Despite the speed of setting, the cured material delivers strong bonding strength, providing a stable and durable foundation for your posts. Whether you are installing fence panels, gates, or support structures, the postcrete gives you confidence that your structure will stay solid and upright under load and over time.

Thanks to its ready-to-use design, this product reduces mess and waste. You save time by eliminating the need for separate mixing trays, wheelbarrows, sand or extra cement. It’s especially useful for DIYers or smaller jobs where mobilising traditional concrete mixes would be overkill.

The flexibility of this postcrete means it works well with a variety of materials — wood, metal, concrete, or composite posts are all compatible. The fast setting time also lowers the chance of jobsite delays (due to weather or logistical issues), as you don’t have to wait hours for the concrete to cure before moving on.

Overall, this is ideal for installations where you want to combine reliability, speed and convenience. Use it when you want a no-fuss, high-performance anchoring solution that stays strong over time.
