Mixing post mix concrete is a breeze! Just add water to the dry mix in the bag, stir it up, and you’re ready to go. It sets quickly, so make sure to have everything prepared before you start. Perfect for those DIY projects in the garden or for putting up a new fence! Post mix Concrete for Fence Posts – Fast Setting, Strong & Reliable
Post mix concrete is a specially formulated, fast-setting concrete designed to make installing fence posts, gate posts, pergolas, decking supports, and other structural timber quick, simple, and secure. Whether you are a professional installer or a DIY enthusiast, Post mix provides a strong and durable foundation with minimal effort, ensuring your posts remain firmly in place for years to come.
One of the biggest advantages of Post mix is its ease of use. Unlike traditional concrete, which requires careful mixing with sand, cement, and aggregate, Post mix is a ready-to-use blend. Simply pour the dry mix directly into the hole around the post, add clean water, and allow it to set. There is no need for complicated measuring, mixing trays, or additional materials. This makes installation significantly faster, cleaner, and more efficient, especially when working on large fencing projects or multiple post installations.
Post mix is specifically engineered for rapid setting. Typically, it begins to harden within 5–10 minutes and achieves a firm hold shortly after, depending on ground conditions and temperature. This quick curing time allows you to complete fencing lines much faster than with traditional concrete, reducing labour time and ensuring posts remain straight and stable during installation. It is ideal for use in both domestic gardens and commercial landscaping projects where reliability and speed are essential.
Strength and durability are at the core of Post mix performance. Once fully cured, it forms a solid, weather-resistant concrete base capable of supporting heavy fence panels, gates, and timber structures. It withstands harsh weather conditions including heavy rain, frost, and temperature changes, helping prevent post movement, leaning, or loosening over time. This makes it a trusted solution for long-lasting fence installations across the UK, where ground moisture and seasonal weather can affect stability.
Post mix is suitable for a wide range of applications. It is commonly used for installing wooden fence posts, concrete posts, metal posts, gate posts, pergola supports, rotary washing lines, signposts, and garden structures. It works well in most soil types including clay, soil, and mixed ground conditions. Whether you are building a new fence, replacing damaged posts, or constructing a garden feature, Post mix ensures a secure and professional finish.
Using Post mix correctly is straightforward. Start by digging a hole approximately three times the width of the post and around 600mm deep (depending on fence height and ground conditions). Position the post upright and ensure it is level. Pour the Post mix evenly around the post until the hole is filled, then slowly add the recommended amount of water. The mix will absorb the water and begin setting without the need for stirring. Hold the post in position for a few minutes while the concrete firms up. For best results, avoid disturbing the post for at least 15–20 minutes and allow full curing over the next 24 hours.
Another benefit of Post mix is its clean and convenient packaging. Typically supplied in durable, weather-resistant bags (commonly 20kg), it is easy to transport, store, and handle on site. Each bag provides consistent performance and predictable results, helping you calculate exactly how much material is required for your project.
In summary, Post mix is the ideal solution for anyone looking to install fence posts quickly, securely, and professionally. Its fast-setting formula, ease of use, and long-lasting strength make it an essential material for fencing, landscaping, and garden construction. Whether you are installing a single post or completing a full fencing run, Post mix delivers reliable support and peace of mind with every use.
Post mix concrete is widely used across fencing and landscaping projects throughout the UK due to its reliability, convenience, and professional results. It is particularly popular for securing timber fence posts, concrete fence posts, garden gate posts, pergola posts, decking supports, and outdoor structures where a strong, stable foundation is essential. Fast-setting Post mix helps prevent post movement, reduces installation time, and improves long-term fence durability. Suitable for both residential and commercial use, it performs exceptionally well in varying soil conditions and challenging British weather. When combined with quality timber posts and proper installation techniques, Post mix ensures your fencing project remains straight, secure, and built to last for many years.
