The mix is a kiln dried, pre blended, factory produced quick setting concrete which hardens in approximately 10 minutes after water addition, depending on ambient conditions.
Mixing Instructions: Dig hole to required size for post, half fill hole with water & place the post in the hole.
The material is already pre mixed & there is no need for mixing, it can simply be emptied straight from the bag into the hole.
Add the Postmix uniformly around the post until it is above the level of water. If any dry powder remains visible at this stage, add additional water until absorbed by material. Adjust the post into position & support appropriately until material set occurs after approximately 10 minutes.
After Laying: Once concrete has set, cover with earth, grass or decorative aggregate as required.
Typically for a 600mm depth of hole, one bag is required
