Product Details

Post Mix is supplied as a pre-blended mixture of cement and aggregate, designed to be poured directly into the post hole and activated with water, no separate mixing is required.

This product sets quickly, allowing posts to be plumbed and secured in a fraction of the time required by traditional concrete mixes. The smooth, fine finish ensures a neat and professional result for every installation.

The amount of Post Mix required will depend on the size of the hole and post, with one bag typically suitable for a 100mm (4″) square post in a 200mm (8″) wide by 750mm (30″) deep hole. Also known as Rapid Set Post Mix, Post Mix Concrete, or Postcrete, this product provides a convenient, consistent, and dependable solution for all post-setting applications.
