Post Mix Concrete (20kg Bag)

Ensure your new fence is rock-solid and wind-resistant with our Post Mix Concrete (20kg Bag). Often referred to as ‘postcrete’, this fast-setting formula is an absolute essential for any fencing project, providing a permanent, heavy-duty foundation for your property boundaries in Hertfordshire.

Designed for incredible ease of use, there is no messy pre-mixing required. Simply fill your post hole one-third full with water, pour the dry mix evenly around the post, and let the rapid-setting formula do the rest. It sets in just 5 to 10 minutes, allowing you to move on to the next post and install your panels without delay.

Whether you are working in damp winter conditions or the heat of summer, this high-quality mix guarantees a highly durable anchor that will prevent your fence from leaning or shifting over time.

We recommend using 1.5 to 2 bags per post for a standard 2ft deep hole. This mix is the perfect companion for securing our Wooden Fence Posts and our heavy-duty Concrete Fence Posts.

Note: Due to the nature of our materials and manufacturing processes, the colour and finish of your item may vary slightly from the images shown.
