In the sidebar to this video there is a video comparing Sika to Secure Set. The video is by Secure Set so likely a bit biased and from what the comments say Secure Set is a fair amount more expensive. Still, it might be another product worth testing out. Have you ever replaced items that were installed with Sika? I'm imagining it has to be easier than dealing with concrete.
Hey man im 18 and im doing the same thing with my mailbox, bought the foam due to its claim, watched your video and its all set up nice and clean. Appreciate the content and hope you do well!! Thx
In hindsight, the one thing I would do is to put painters tape just above my "at grade mark" to keep the form off my post. I splashed a little bit as I was pouring. It would be a lot easier to tear some tape off than to scrub/scrape the foam off. 👍😁
@@AccentAlarms - Know how a driveway is leveled? They use this type of foam. Have dealt with leaking basements due to settling issues since the soil put back is not as solid as it was when it was undisturbe which is why most utility poles tend to lean due to said disturbed surrounding soil reintroduced and was not quite properly compacted .. or it was ... but settled due to imperfections in said back-filling technique. Thus why said expanding foam makes more sense than back-filling with concrete. Same could be use for filling sinkholes.
Hey Sean. I work for an electric company and can confirm we do use a polyset product when setting electric poles. Seems to do a pretty decent job, at least the linemen and construction teams like it. Don't yet have definitive data on its longevity, but that'll come in time. Have a good one cuz.
Basically, the post still wobbles. And since the material is spongy, once you push it, the non-expansive material will remain so and leave a gap, so that the post will now wobble even more. The product, an expanding foam, is best used for its intended purpose to fill a hole (eg, similar to the expanding insulation they use inside homes and garage walls for insulation. But not for supporting posts. ---- It would be an INTERESTING EXPERIMENT, if one could "accent" this quickly-expanding material, by somehow incorporating small pebbles/stones into the liquid mix, so that as it expands, it expands WITH the stones inside, as a matrix, and thus making a kind of cement floating in a plastic material. (Someone should try this). Better even, chopping up some small wire, 12/18 gauge, into small 1 inch lengths AND also pebbles --- then poring that liquid (and wire/rock addition) so that as it expands, it incorporates that inner metal/rock network and really hold the post to the outside circumference of the hole?! Try that and let me know.
I'm a bit on the fence with that one. 😂🤣😂 I've not done that setup myself, but I believe given the airflow of the lattice it should be okay as you won't get much wind-load on it.
I would recommend this for a non-load bearing post. A chain link line post (in the line) but not for a corner or end post. When it dries it is similar to spray form (e.g. squishy). I has worked great for my mailbox and I would use is for mounting objects on a post, in my case cameras, wireless radios and similar devices. Hope this helps. :)
@@AccentAlarms - Squishy? Sure if you have not waited for it to set for 15 minutes, or then tested it again after 24 hours or so since it actually sets pretty hard! But yeah it would not fair well for corners since it only hold stronger than the soil surrounding it.
A gentleman that does fences did a video - after sitting for 3 days the foam had contracted and it was loose in the ground and around the posts. Did you have the same think happen?
@@AccentAlarms Don't know what happened between cuts - he poured it, then 3 days later evaluated it and it was loose. He's supposedly a professional fencer - Ozark Fencing I think was the name.
I am about to use some on my mailbox that I am installing. Thank you for the advice.
Mine is still holding up without any issues.
Looks great!
Thanks for sharing, I’m headed to Home Depot to pick up a bag.

I'll have to look into that. I think it could be a pain to remove Sika/foam, but your right easier than concrete and definitely not as heavy! :)

Worked for me
Good info 🤙🏽
Thank JoJo
They've been using these things out west to set telephone line posts
Doesn't overly surprise me, I'd guess over time the poles could lean/shift a bit but being slightly out of level isn't going to hurt anything.

It doesn't claim to be for structural posts.
Would you use it on a two-panel 4'x8's lattice privacy fence with three 4x4s?
I'm a bit on the fence with that one. 😂🤣😂 I've not done that setup myself, but I believe given the airflow of the lattice it should be okay as you won't get much wind-load on it.
Looking to put in fence posts , would you not recommend this for that ?

A little late but...NO!!!!
The stuff is garbage...
Shouldn't be necessary to use two bags. Use use one bag and use leftover dirt to backfill.

I did not have this issue. I wonder if he didn't set his posts deep enough, didn't clean out his holes, or maybe made ice-cream cone shaped holes?

Terrible product..is way to soft and spongy...i ended up digging my posts out removed foam and used Rapidpost at 60% cheaper.
I have good luck, but I've used it for a mailbox and photo beam mounts (e.g. not much load). Thanks for sharing your thoughts and experience!
