Foam Vs Concrete For Fence Posts

I used one of the heavy steel digging bars with a narrow spade on one end and an enlarged tamper on the other end.

Foam vs concrete for fence posts.

Be mindful of how much water you add. Concrete is cheaper and pretty fool proof vs. Also you do not have to cement every hole i do every other and the corners and gate support posts. 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.

He also noted that the foam was a lot more expensive. I replaced termite riddled cedar installed with concrete with pressure treated. He said they still preferred concrete with two exceptions. 02 02 2016 10 02 am re.

The spade end was perfect for breaking up the existing concrete and then i extracted it with post hole diggers. 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 were at a site where there wasn t easy access to water. Do not exceed limit written on bag of concrete.

So six foot high fence posts ideally need to be buried three feet into the ground. The soil was a heavy black clayey soil. For a fence i think its fine to mix in hole but i find it is far easier to mix in a wheelbarrow. The advantage for me is i could set a post by myself using a very simple system of temporary braces to hold the posts for 15 minutes until the foam set up.

Here i would use a 5 8 minus unsifted with all the powder the comes from the crushing process. Setting posts in concrete vs. To make a long story short i ended up setting all of the posts in this high density foam in lieu of concrete. If they had tight time constraints and they needed the posts to be set up earlier than concrete would give them.

Expanding foam by meackerman the fence posts i ve if you go the gravel route the type of gravel makes a difference also.
