    How much postcrete do I need for each wooden post?


    Hello all, I need some advice for how many bags of postcrete I will need for a new fence I will be putting up. The posts themselves will be 2.4m wooden posts for panels that are 1.8m by 1.8m. The posts will be put in soft and sandy soil. Can anyone give me an idea of what the bag to post ratio would be?
    Many Thanks, Bill

    "Hi Bill,
    Depends on the holes and their depth really. Typically, I would expect 1 to 2 bags per post in my own experience, but your rates may vary a bit. I should think 2 bags per post would be the safe option to make sure you don’t run out."

    "You will need to dig 450MM down into the ground and also around 450mm wide. The post will go in the middle and then you will use around half a bag of postmix and also use around 1-2litres of water mixing as you hold the post in place. You will require an additional person to hold the post whilst pouring the mix in. When your postmix is drying leave a slope type finish to rot the wood."

    "Hi for each post you will need at least 1 and a half to 2 bags per hole depending on width of hole."

    "Hi Bill, you will need 2 bags of postcrete per fence post. Also, remember it sets in 10 minutes so make sure to have the post level before that time.

    "Depends on the size of the holes but normally it's a bag per post. I have personally found that it's better to have 1 and a 1/2 bags, also dont mix it too wet, otherwise it takes a while to set and it's time consuming."
