Post Mix

Postmix

Postmix is a fast-setting, ready-to-use concrete mix designed for fixing fence posts quickly and securely into the ground. Ideal for fencing installations, postmix provides a strong and reliable foundation for concrete fence posts, timber posts, and a wide range of outdoor applications where speed and strength are essential.

Supplied as a dry, pre-mixed compound, postmix simply requires the addition of water once poured into the post hole. This makes installation quicker and cleaner compared to traditional concrete mixing, reducing labour time and eliminating the need for mixing equipment. It is a popular choice for both professional installers and DIY projects.

Postmix is commonly used to secure concrete fence posts, including standard intermediate posts, end posts, corner posts, and 3-way posts . When used correctly, it helps lock the post firmly into position, reducing movement and improving long-term fence stability. It is also suitable for timber posts, gate posts, pergola posts, and other ground-fixed structures.

One of the main advantages of postmix is its fast-setting performance. In most conditions, posts can be set and supported quickly, allowing fencing work to progress without long waiting times. This is particularly useful on larger fencing runs or projects where efficiency is important.

Postmix performs well in a variety of ground conditions, including soil, clay, and mixed ground types. Once cured, it forms a solid base that resists movement caused by wind, ground shift, or regular use. Correct installation depth and alignment remain important to achieve the best results, particularly for taller or heavier fence posts.

When installing concrete fence posts, postmix works perfectly alongside concrete gravel boards, helping create a strong and durable fencing system. Gravel boards protect fence panels from ground contact, while postmix ensures the posts themselves remain firmly anchored, improving the overall lifespan of the fence.

Using postmix also helps maintain consistent post alignment. Once the mix is poured and the post is positioned correctly, the setting process holds the post securely in place. This helps ensure fence panels sit straight and level, contributing to a professional finish across the entire fence line.

Postmix is supplied in manageable bags, making it easy to transport, store, and use on site. The quantity required will depend on post size, hole depth, and ground conditions, but as a general guide, one bag is often sufficient for standard fence posts when installed correctly. Deeper holes or larger posts may require additional bags.

Because postmix is pre-mixed, it delivers consistent results every time. This reliability makes it a trusted choice for fencing contractors and homeowners alike. It removes guesswork from mixing ratios and helps ensure each post is fixed to the same standard.

Postmix is suitable for both new fencing installations and replacement work. It can be used when replacing damaged or failed posts, allowing quick reinstatement of the fence without extensive disruption. This makes it ideal for repair jobs as well as full fence replacements.

For best results, post holes should be dug to the appropriate depth and width, with the post positioned plumb before adding water. Once the postmix is poured in and watered, it should be left to set without disturbance. Following the manufacturer’s guidance will help achieve maximum strength and performance.

If you’re looking for a quick, reliable, and easy-to-use solution for fixing fence posts, postmix is a practical and dependable choice. Designed to work seamlessly with concrete fence posts, gravel boards, and fencing systems, it provides a solid foundation that helps ensure your fence stands strong for years to come.

It is suitable for domestic gardens, boundary fencing, repairs, new installations, and professional trade use where reliability and speed are essential.
