As a carpenter I would never of done what you just did there, I would secure all posts with braces first to keep plumb and then fill the holes all in one go. As a side note I’m a big fan of expanding foam so using this is interesting

[@gedionatphysicsmathelectro1867]

So this thing can withstand water and snow?

[@dangerous119]

Vertical adjustment is called "plumb.". The reason why your code wants you to place concrete at the bottom of your hole is so that you'll have stability below or at least close to your frost line. The depth in the ground above the fridge line can freeze and thaw, which causes expansion and contraction. This leads to heaving of the structural element. If you see a lot of freeze/thaw in your area you really want that movement to not affect your post. Your bridge is load bearing, it is bearing the load of the bridge itself (dead load) and the people walking on it (live load).

[@shawnreems493]

plus snow load lol his bridge should sink over time. Wouldn't really recommend for load bearing applications especially with no conc. pad. If he did conc. pad and then this i dont see why it wouldn't work. Plus if you just set your conc. above soil line you wont get any rot or anything as water cant pool up against the post so dont really understand him saying that.

[@rexfairholm8017]

One bag will do 2 posts. Says so on the bag. Keeps you from having to trim it. I just get two posts ready, pour half in each. Plenty of time to set them. It’s helpful if you get the posts level and held with wood stabilizers first so you’re not scrambling.

All they asked was how much foam did I need. GREAT customer support. Do a foam post install on a 75F or higher temp day. Foam needs heat and creates heat in the chemical reaction of curing.

That is THREE moves to get the concrete to the hole. I did 20 posts which would of been 4800lbs total with 3 moves. Foam was about 20lbs?? LOL. No water mixing and all that dust in your lungs. Price was a wash compared to concrete for my job. It's also 6lb foam. Not like the stuff you buy in the spray cans. It's waay harder and stronger by a long shot.

The bags weigh a lot less than concrete and you don’t have to worry about breathing in the dust from the concrete or the concrete getting on your skin and burning you. Really cool and looks like it’s worth the extra money. Down here in South Florida it’s all sugar sand and coral rock so this stuff would work great with all the humidity and rain we get.

[@jimyeats]

I agree with you, or even better, just buy a bag of portland cement for 6 bucks and mix your concrete on site. Work harder, but have 5x the amount of made concrete for the same price. Everyone has their level of effort vs price that they are comfortable with. I could absolutely see this as worthwhile for someone doing limited posts that are non structural such as a mailbox.

[@BeckVMH]

Replacing a mailbox post destroyed by a hit & run driver and this or similar product was used to secure the former post. The hit & run vehicle had shattered both the 4x4" vertical AND the horizonal posts at the top, but the base of the post where secured inside the foam had never budged and was not loose at ground level. I had assumed it was installed in concrete. Pretty impressive. The foam base may have absorbed enough of the impact to prevent the vertical post snapping off at the base, but just a guess. I wasn't familiar with the product until removing the damaged post and doing a web search. The foam was very dense, but could still run my shovel through to remove. I plan to use this to install my new post.

[@kevinschomisch]

Concrete is far superior if you want the job to last. These foam products expand great but also contract within a day or 2 leaving a gap around the post and the perimeter of the hole. Once the fence3 is erected you will not notice that the posts are loose of course. Check a post 2 days after install without a fence erected and you will have a loose wobbly post. Honestly most fences will be fine using this product however concrete is far superior for longevity! PRO-TIP--Coat the bottom 2-3 feet of your PRESSURE TREATED 4X4'S to prevent rot where the post meets the concrete ( or foam) and coat the top of the post also or put a cap on each post. The top is open grain and melting snow, rain etc will soak in weakening the post over time. Maximize your results by taking a few minutes to do the little extras that ensure a great fence.

[@rickjames6948]

Concrete is superior??? I used Secure Set foam on 20 posts. Price was nearly the SAME as Secure Set foam. Now you have how many TONS of concrete to load on a trolley? AND lug it through the store. Then load it into a truck YOURSELF. Then lug many TONS of concrete to each hole. Needing water and all that crete dust in your lungs later.... Here's another one. Concrete absorbs water like a sponge. Wood does the same. See where this is going? Foam doesn't absorb water people. Foam is waaaaaay lighter to finally get to each hole LOL LOL.

[@frankie7508]

This demonstration was a good, practical one. It is commonly referred to as structural expanding foam. But I caution people that it does not replace concrete because it simply does not have the compressive strength. It would have been helpful and more informative had the novice simply told us the performance test figures shown on the bag in terms of ultimate compressive and tensile strength. Another important factor is that the foam does not plastically yield, but rather fails immediately with no premature warning. Whereas concrete, engineers and scientists know a great deal about Its Behavior under load as well as what conditions cause it to break down. Structural expanding foam has not been used nearly as long and so we know much less about it. I think it would be very dangerous to use this type of foam as indicated in this demonstration because tgere is no apparent use or installation of any fixed lateral or cross bracing between his posts and so the application is Reliant solely upon the structural foam for these directional loads. It's very dangerous and borders on foolishness and dangerous. Using this material for a fence post is one matter. Using it to support a load that will carry people is quite another. It's the problem with KZbin, anything goes and so the buyer must beware. When it comes to using materials of construction for their intended purpose, it would be very wise to seek the advice of a degreed engineer or a construction worker with Decades of experience who has seen and used the material in both methods of success as well as failure. I caution any viewer of this KZbin video not to use the fiam without relying on proven structural Materials and bracing. Another source of useful information is to contact the manufacturer of the structural expanding foam for technical guidance. It's simply not worth risking life and limb using a product that is beyond its intended purpose and use.

Post hole levels are good only if you are ok with each post being close to plumb. It only covers about 6" of the board. What about the rest? If the board has a crown, which most do, it's good to know that where ever the 6" is that you put your mini level is plumb. The rest is going wherever.

[@jamarnicholas5697]

For a fence I can see yes for a deck No! A fence moves lateral while a deck has weight going down. So you need a pad in the bottom to support the weight and your deck shouldn't have any side to side or lateral movement. So your porch will still settle. Essentially your post is sitting on that three and a half inches versus where if you had 12 inches of concrete pad on the bottom it would be sitting on that 12-in pad. That's most of my 2cent

The top is mixed but not below. Not all the way to the bottom of the hole as it needs to be. Mixing concrete in the hole is the lazymans way & it is a halfass technique. To do it right, the concrete needs to be mixed OUTSIDE the hole. You do want to do a good job, right? I HATE mixing concrete thats why I used this foam for my mailbox post.

You really only need about half a bag per post. Given that the foam is roughly $10.50 a bag, concrete is still less expensive at $3.15 a bag. Foam per post $5.25 Concrete per post $1.57

[@Komputar]

You have to add in delivery cost for concrete

Did it shrink or did it keep it solid in place?

Still doing great. Really happy with this product 👊

what timing i have to replace 2 fence posts im going to try it

Let me know how it works out bro👊

Wazzup!!!!!! Bro THANKS for the info 👍🏼

Thanks JR!!!

Hopefully you’re still checking comments, did this stuff kill the lawn surrounding the post hole? Wondering about chemicals in the dirt

[@ToolReviewZone]

No, everything is still fine

[@davez2989]

Looks like 1 bag could do 2 posts

[@elizabethbuslon7271]

I noticed you didn’t mix property rubbing it in your thigh … while he was kneeling down … with foot … base on their video o watched

[@suqmadiq68]

Isn't this for fence posts?

[@AB-nu5we]

Joe Everest on his fencing channel had very different result (not good). Hmmm...wonder what the difference was. If you used a concrete pad at the bottom and he didn't, that might explain it. I don't know. Ineresting.

[@ToolReviewZone]

I just watched it. I'm wondering if there is a difference between using a metal post or 4x4 lumber? I haven't noticed any of those issues, but maybe I'll try with some metal posts to see if I get the same results

[@ToolReviewZone]

Very possible brother. I really enjoyed you video 👊👊👊

[@banksj54]

Cool video and thank you. Do you think it's necessary to use a full bag on one post with it being = two bags of concrete. Im using for a mailbox post im thinking a 1/4 bag should be sufficient

[@MaxxsHandle]

Better to have it and not need it than need it and not have it

[@pamelah6431]

Problem is, you have to use 100% of it as soon as the bag is open

[@kieoneyoungphotos]

For one post $15 a bag might be OK but if I were actually setting a fence line there's no way in the world I would spend that much on a bag of this when I can spend four bucks on a bag of quick Crete

[@soldbyoctavio8738]

Nice video but next time you would level the post stake them down then pour it..

[@jaybeezy5429]

Foam loosens up easy, so if any gates are set, it will let go. Concrete is clearly superior

[@robertabiamiri213]

How did you dig such clean 4x4 post holes?

[@ToolReviewZone]

Post hole digger 👊

[@dank9288639]

can you use regular expanding foam for a 2x4 into dirt? It will be a holding up a 1lb security camera

[@ToolReviewZone]

It should be just fine.

[@wht240sxka]

2 questions. Hows it do with weather like rain or snow getting down along the post and heaving it when it freezes? When the post is setting up, does it try to lift the post out of the ground?

[@AkSonya1010]

It does fine in rain, we have had 3x the amount of rain this summer and it's doing fine. it does not raise the post up. It just expands not compress. I am not happy with it. The foan is not hard, my post is wobbly, I wouldn't us it again.

[@future8783]

Bro how many times you gonna move the column and level it??🤦🏻‍♂️

[@ToolReviewZone]

Well come and help me then "bro!"

[@life_score]

Holes not wide enough, that too is why it’s pouring out

[@GunSlinger221]

I have so been wanting to try this stuff, I cannot beleive that it is strong enough to hold any type of load. I bet this stuff is light, will not load my truck down like concrete. Just have to wonder if it can be used on decks, or any place where you are going to have people traffic. I sure wouldnt want som,ething to fail.

[@ToolReviewZone]

It's been holding awesome so far. Haven't had an issue

[@rickjames6948]

Power companies in Texas and Oklahoma use foam all the time on big stuff. Much larger than a 4x4 obviously.

[@cfrench61995]

Question, can this stuff be used to fill part of an unground pool?

[@ToolReviewZone]

Fill in the pool or around it?

[@CallSignWhiplash]

Utility companies call it pole foam

[@MTECH909]

Do you think it can be put inside a vinyl post to strengthen it up wo cracking the post?

[@ToolReviewZone]

Might work OK. I would only use a little bit just incase though

[@sparlin88]

Use Fast 2K ! Much Much Better and doesn't shrink like Sika

[@amoscardoza5253]

They tell you 15 seconds to keep you on point.

[@ToolReviewZone]

That's what I was thinking. I was running around like my ass was on fire trying to get it level within 15 seconds lol

Hey brother, didn’t realize you were in Ohio. Eastern or Western Ohio?

[@ToolReviewZone]

What's up bro. I'm in the Youngstown area (eastern Ohio) where you at?

[@johnnyllooddte3415]

youre supposed to be able to do 2 posts per bag

[@FJBsaidcornpop]

I will stay with old fashion concrete. My grandfather set two solid metal posts in the ground for a clothes line in 1977, the concrete is still the same today as it was poured, 45,+ yrs ago and counting. Do you think that foam would have made it this lon? c Nope, it will turn to dust

[@brucecave8937]

This product is not for vertical pressure only for horizontal pressure like wind on a fence. your poles will sink .

[@rickjames6948]

Show us a picture of YOUR fence and all those sunken in posts. Another zero credibility comment.

[@high_fructose_corn_syrup]

Looks like great stuff foam to me..

[@yorkiepit]

Great product for fence posts, but the product is for non-structural purposes only, it won't meet IRC code, anywhere, for use as a deck post footer.

[@jimyeats]

Well, to be fair, he wasn’t using it as a footer. The post is resting against the ground, just like the myriads of decks built with the posts directly buried. The foam is just basically acting as a lateral stabilizer. Granted, do you want wood posts that are structural just buried in the ground? Maybe not, and certain areas don’t allow it, but other than arguing about long term buried wood durability, there isn’t anything unsafe about how he did it. Now, if he poured in the foam and then put the wood on top of that…..

[@user-fd6oo8rf4v]

Not a good way of setting a post using foam. The post should be set level and supported with a few props to hold it whilst you set the level. Then you pour the foam, and it sets as it should. If you move the posts to set a level whilst its expanding, you introduce potential weakness to the foam and the movement means the post doesn't set as strongly as it would if you supported and levelled the post before adding the foam mix.

[@tarricjomaa2515]

I used this when it was hot outside it expanded so fast in the bag it exploded in my face lol be careful.

[@ToolReviewZone]

Lol, dayuuuum 🤣 thanks for the heads up Tarric!

[@MP-vd6ho]

Any updates?

Still holding awesome

[@B.E.C.K.]

What region are you in? I have an upcoming fence project where the frost line goes down around 4 feet in the winter. I’m putting together my material list and was planning on using 2 foot deep holes filled with Quick-Crete until I saw this foam product. Now I need to look more into using foam in my climate zone and check with the building inspector. Thanks for the content! I just subscribed

Does the bag give a recommendation on when to trim the excess above the ground ?

[@ToolReviewZone]

You can just cut it flush with the ground

[@krissanchez4816]

@@ToolReviewZone I understand that. But does it give an approximate time that it will be too hard to trim
