Foam Vs Concrete For Fence Posts

He said they still preferred concrete with two exceptions.

Foam vs concrete for fence posts.

I replaced termite riddled cedar installed with concrete with pressure treated. Expanding foam by meackerman the fence posts i ve if you go the gravel route the type of gravel makes a difference also. Do not exceed limit written on bag of concrete. Here i would use a 5 8 minus unsifted with all the powder the comes from the crushing process.

I used 4 braces per post. To make a long story short i ended up setting all of the posts in this high density foam in lieu of concrete. The soil was a heavy black clayey soil. Also you do not have to cement every hole i do every other and the corners and gate support posts.

If they were at a site where there wasn t easy access to water. Be mindful of how much water you add. The general rule of thumb when setting a post is that the depth of the post s hole needs to be 1 3 to 1 2 of the actual above ground height of the post. The diameter of your post hole should be three times the diameter of your post.

I used one of the heavy steel digging bars with a narrow spade on one end and an enlarged tamper on the other end. He also noted that the foam was a lot more expensive. The foam like i said in the post there were possible issues with maybe the weather or the depth of the hole etc but if the whole point is to beat concrete i still say this failed in that respect. If they had tight time constraints and they needed the posts to be set up earlier than concrete would give them.

Its only one bag per fence post so its not a big deal. 02 02 2016 10 02 am re. Setting posts in concrete vs. So six foot high fence posts ideally need to be buried three feet into the ground.

Concrete is cheaper and pretty fool proof vs.
