Concrete vs Post Foam...Which is Better?

You pulled that post out and it only had a thin layer of color on it? The foam I use turns into a solid block that you would have to use a Sawzall on to even think about separating it from the post. Something went very wrong with this little experiment. For what it's worth, around where I live they use foam to set telephone poles. They wouldn't trust a huge pole that could fall and kill someone to a product that simply doesn't work. I've never seen one of the polls even shift a tiny bit, much less lean.

The shadows and clouds never moved lol

Interesting video. I’m finishing a fence this week and used Fast 2K post foam for the first time. I was able to let the post go in 1.5 minutes and it can hold a load in 3. Must be mixed reviews based on your he chemicals used in the foam products. Thanks for sharing.

You needed to use a bit more post foam, it wasn't even to ground level

Meh, it depends on the chemical make up of that post.

90% of fences will never seen that type of abuse. That stress which you put on it is just ridiculous and i only see that being an isue for a farmer like you that has a half ton animal to worry about. The rest of us with residential homes, swimming pools, and bar b q grills really dont need the extra strength and honestly I would not judge the Silka foam type post material by the way you installed it if you wanted it to be its strongest. I suggest throwing some wooden blocks about 2.5 inches cubed ainto the hole with the foam and maybe even a few scraps of rock the size of softballs so they get stuck in the middle of the hole if you really want it more sturdy. Usually I only use foam for residential installs of short fencing and repair work. Using it for large post holes for a farm is just ridiculous and like using a garden shovel to go dig up a city water main and a 4 foot diameter pipe and then complaining that it doeant do the job as well. Get the right tool for the job and when you have a storm and you are cleaning up your home and the 6 foot privacy fence vlew down with 3 posts coming out of the ground you will be thankful Silla is there and you can repair the fence quickly with 3 bags from a local hardware store because home Depot is an hour away and you have 5 other things yo do like cut fallen trees into pieces and put them at the curb, blow off all the muck that flooding brought and high qinda xaused to fall, and repair a few pieces of siding or trim or even a broken window. Silka is good for residential decks, residential fences, residential mailboxes, and residential light posts. That is a light post that is 5 feet tall or 6 at the highest. Not 14 feet tall or 20 feet tall. You get it? . Silka is good for a garden trellis that is 6 feet tall. Not a city picnic shelter at your local park that spans 40 feet and has 8 inch diameter metal posts. Silka is even up to code for a residential wooden privacy fence at 6 feet tall and will last longer than the cross supports will on a 6 foot fencing panel when they are ruined by rain erosion. It takes about 20-30 years for a properly built fence in a high rain area to rot out its cross supports. Silka will stay its ground in hurricane winds and if a fence is going to blow down with silka then a concrete post is only going to make it break or it will just do the same and fall over. Silka is even good for stairs and handrails and pergolas but you have to choose your battles and if it is a handrail that is skinny metal, like 2 inch diameter, then use concrete because the thin metal will rip through the foam and come loose without a bunch of pieces of hard material in the post to prevent it from moving. Expanding foam works as a mass and has some give. It isnt as strong as concrete but passes code and in 90% of places in the United States at least it is plenty and males life easier and will outlast the rest of the fence and wont vlow over even in high winds. No 120mph winds though. Those are enough to break any fence out the ground. Not just foam.

Why don't you guys just use a screw piles for foundation these wooden piles to STAY in the soil forever!😊 Screws drilled to the ground less than ten minutes each then just add the wooden parts on those. Voila the fence is there for decades to stay!😊

Foam sucks. Concrete is the tried and true method. Foam leaves no counterweight like concrete does and doesn’t harden as firm either. Foam is just another way to make your job easier and create job security by making a product that doesn’t hold up over time and under stress and ends up having to be redone sooner than expected. It’s just so someone could make things cheaper.

Hmmm....I didn't have the same experience using foam to set a temporary fence. That fence was in place for about a year and even after sledging on it and using a farm jack and a choke, those 4x4 posts (7 of them) would not pull out. Ended up sawing them off at grade. Now watching this video, I'd say your level of vigor while attempting to remove was much higher on the foam post.....seriously, you hardly tried to push on the cement post. Great video if you are trying to justify additional labor costs........great entertainment though!!

I can’t stand these videos were there is music over the guy speaking. Why? Nothing creative or entertaining about that. Annoying.
