How dry does the ground need to be in order to use postcret? I'm in norcal and we've had tons of rain. The ground is real saturated at 1 1/2 to 2ft.


Dry enough that there is no standing water after "sprinkling" it on the ground. (It's not a structural product, (no compressive strength,) so it's not critical to structural performance.

  • I have put in posts with standing water in the hole and added the mix dry. I do usually over fill but it has worked well. – Ed Beal May 11 '17 at 19:08
  • @EdBeal I doubt if you can find any agency, association, (Portland cement association), etc. that would "recommend" pouring into water is "best practices." – Lee Sam May 11 '17 at 23:45
  • I believe if putting the mix in the hole dry or not pre mixed some water in the hole first works better than adding water after filling the hole with the mix. Yes the water is supposed to be potable but if there is high ground water getting the hole dry is not realistic. I have put in many fences that I used this method and as I said it worked well. – Ed Beal May 12 '17 at 12:55
  • @EdBeal If the hole is full of water, how do you measure the water? How do you control the water-cement ratio? – Lee Sam May 12 '17 at 14:52

    The mix displaces the water its a post not a structural member some water in the hole works better than trying to add water after the mix is in the hole especially with clay. – Ed Beal May 13 '17 at 3:44
