    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."

    "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."

    "Usually two bags of postcrete per hole. What sizes are the post? 75mm X 75mm or 100mm X 100mm in old school 3"x 3" 4"x 4" but it all depends on the depth of the post you are putting in. I usually dig out to 600mm.
    Hope this helps you. Cheers, Russ"

    "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.

    "The standard is 1 1/2 bags per post, I use 2. Try your best not to dig a hole too wide. I would suggest picking up some fence post hole diggers to make the job easier. They are usually around £35-40."

    "In my experience 1/2 to a full bag will be needed. I always make sure the concrete comes near the top of the excavation. Just remember to use plenty of water."

    "Usually one bag of postcrete per post is enough, however you can use a two bags per post if you feel this is needed.

    The instructions are on the bag."

    "Hi Bill,
    I hope my message finds you well.
    You’ll need to bury the posts at least 2ft In the ground. As for how many bags of postcrete you need per post, that’s purely dependant on how big you make the post holes.
    As a rule of thumb, when using standard post hole diggers, I average 1 bag per post.
    For larger holes I would allow 1.5 bags to 2 bags per hole.

    I hope this helps.
    Kind regards,
