Our 20kg bags of Post Mix Concrete are suitable for use in fixing all types of wooden, metal and concrete posts. 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.

Features:
Quick setting - Approximately 10 minutes from adding water
Easy to manage 20kg bags
Plastic bags prevents splitting
Consistent, strong hold

Mixing Instructions:
1) Dig hole to required size for post, half fill hole with water & place the post in the hole.
2) The material is already pre mixed and there is no need for mixing, it can simply be emptied straight from the bag into the hole.
3) 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.
