POSTSAVER Fence Post Concrete Foam Resin Proset 1 Pack Equal to 40kg Postcrete Concrete

Used the product to reinstall a washing line that, over a period of years, had become very loose in a wet lawn. Dug the old base out and, using this product, reinstalled it. The washing line is now vertical and extremely stable. For my particular needs, the bag was probably a little too big and the resin bubbled up out of the hole and dried. For something deeper, like a fence post, the bag size would be ideal. However, it was extremely easy to saw the surplus off flat and then cover it with a thin layer of earth to make to make it a tidy job.

Definitely worked as described. Extremely lightweight and you do have to move pretty quickly once the package is opened. With the exception of a minor user error, explained below, it was incredibly easy and I'd def buy it again. As you can see in the photo, I didn't use it to mount a fence post but the concept is the same. I made a narrow hole in the dirt in the basket and pushed the post down in it, then used the whole package. the product began expanding and spreading all around in the basket, I guess because it was very loose dirt and not the ground, so the foam was seeping everywhere. So, I quickly grabbed a garden tool and started scooping it all back to center while it hardened, hoping that it would still work to keep the post secure and that I didn't waste it. It DID! I should have put a smaller vessel inside the basket and poured the product into it to keep it more contained. But in the end the result was excellent despite my user error. Oh and you don't want to let this stuff dry on your hands 😉

I didn't even know about this until Amazon recommended it after I put two single post handrails in my cart. I was resigned to going to my big box hardware store and buying two 50lb bags of concrete, hauling it up the client's steps in the front yard and mixing it (on a 95 degree high humidity day) complete with all the dust and mess of cleaning my tools. I really had my doubts but almost all of the reviews were stellar so I took a chance and totally lucked out cuz it worked so well.....amazing stuff !

I used this to mount a post in a ceramic pot as concrete was going to be too heavy and messy. The post was for a bird box. Worked perfectly though I needed to hold the post level for longer than expected as there was a lot of movement when the foam expanded. Good stuff for the job I had.

To be clear, this works well. Open, remove the tube, mix for 60 seconds, pour into the hole. you will have time to set the post, but if you purchase the 2 post pack you will need a friend or have the post in place. This was not so easy to use, but better that cement. The biggest hurtle was that I expect to get to packs to set 2 posts. I received one pack for 2 posts, and this was not easy to measure on the fly while moving from post to post. This was very light, and easy to carry. and it came with a small pack of gloves to protect your hands (I recommend you use them). The product setup well, but we needed 2 x 2 packs for 3 posts dug with a post hole digger because we need to get 3 feet deep.
