Rick, you would need a 1' diameter hole for a 4x4 post. We would also need to know the length of the post to determine the depth of the hole and how many bags you would need. Please reach out to our technical support team directly so we can gather more information and help find a solution. 1-866-725-7383.
Wizard1, we would advise using High Strength Concrete Mix and mixing the material with water outside of the whole to ensure a continuous mix.
