I expected a foam equivalent to what utility companies use, but this stuff although easy to use. It doesn’t secure fence posts like my other concrete ones. I installed some 50 posts. 30 with the foam and other 20 with one 80lb sack of concrete. For 40% cost of foam, I’ll stick with concrete in the future
This is a mess not worth a s could have done same thing with foam in a can it don't hold post good at all sack create is still the best way to go over priced junk
no cleanup needed. used on bag and filled up hole to about 21/2 feet. just tampered dirt to fill the rest of the hole up. after 24 hours, post was very sturdy. wont use cement again.
