Sika Mix-In-The-Bag Expanding Polyurethane Post-Setting Foam Fast Setting 33 -fl oz

Great Stuff!!

First time user. Thought i would try instead of mixing up a small batch of cement for 4x4 8' post in late fall. Filled 2' hole over top, hardened in 30 minutes where you could not move post.

Received as described - Thanks!!

Beats mixing concrete especially for small jobs.

Easy and clean

Science at its finest

Wasn’t sure if the hype was real. I was skeptical this bag could replace to bags of Crete. Sure enough, it works like a champ! I set 2 fence post and it handled the 6x8 fence panel with no problem.
