that once needed instant concrete, like putting in a new washing line, mailbox or fence, can now be done much quicker and easier thanks to Sika’s new Post Fix.
Suitable for wood, PVC, metal or concrete posts, Sika Post Fix turns big projects into easy DIY jobs. So rather than using 60 kilograms of instant concrete to fix one average sized post into the ground, you can do so with just one 1.1 kilogram bag of Sika Post Fix.
The easy-to-mix solution requires no special tools and does not use water. Simply pre-mix in the bag before opening, pour and watch it expand rapidly to fill the hole and fix the post in place. Setting in just three minutes, it hardens completely in two hours, so you can get on with finishing the job. Any excess material cured above the surface of the ground can be cut away with a sharp knife before covering with top soil.
Sika Post Fix has a unique chemical formulation that does not harm the soil or surrounding environment. Once mixed and in foam state, Sika Post Fix is inert and will not leach into the soil.
Available from Hardware & General, Mitre 10, Bunnings and other hardware stores, visit Sika Australia for more information.

I live in South Africa. Where can i get my hands on this?
I found it in my local Lowes store in Severn, MD.
Is this “Wonder” product available in the U.S.? …this sounds so Kewl!! ??
Lowes in MO has it
Is it bouyant? Is my post gonna float when a big rain comes?
??????? I was thinking the same thing! ??
Bonjour, Où trouver ce produit en France ?
Merci
Cordialement
Wow I just checked the price of this stuff and it makes the cost of each post go to $18. Good luck selling it. I’ll stick with mortar mix.
I was a little hesitant to use this product, however when I premixed it in its own bag and opened it and poured it in the hole it was easy and a snap to use. Drying and setting time was about 15 minutes. Deeper holes are better because this expands. Pour quickly this stuff heats up. Sure changed my me about the hassle of pouring. And no it’s not boyant ….. duuuuuuuuuh !!!!
I’ll stick with fast set concrete!! Foam holing in a fence post, common sense screams…. Not a good idea!!!
What temp range does this stuff work.
If it can be cut with a sharp knife the material can’t be as strong as concrete.
Yes and once cut the seal is broken and the pores opened so wouldn’t it take on water? What the when it’s wet and freezes?
Not for heavy load bearing usage! Fence posts are ok. No deck posts though!
Seriously!?!?! Expansion foam? To secure fence posts? What is wrong with you people? Stop with the instant gratification shit. If you want secure fencing, like it or not, you have to use concrete. & yes, R rozales, it is very much buoyant. It’s foam!!! Hence, buoyant. You try & use this on anything load bearing, it will fail. Both from a compression, & rigidity point of view this is a ridiculous product. Anyone with an once of building experience would, & will laugh at this product. Not to mention it’s insanely expensive.
Foam has it’s uses, fence post installation is absolutely not one of them.
This “foam” does not stay soft but turns hard as it dries. If your hole is deep enough it will not go anywhere once dried. I have used it where
I stayed before and can vote for it working. Just fill the top 10cm of the hole with eg. soil/gravel.
Won’t the foam hold in moisture?
In power line construction they have been using a similar product called pole set, in places where the compaction is difficult to obtain, where the hole gets very large and not easy to tamp back. Spray the foam in and it’s the thing that works. Never had a problem. But this is a single hole solution and I’m applauding, as I know how well foam works.
Railway companies use a product much the same to fill old spike holes in railway ties. holds new spikes great, yes this is used everywhere even in curves…
I agree with you Chad 100%
I agree with you wet ground and foam.. I can see my poles laying over now.. folks must not have a tight fence if this crap works for them lol..my fences are tight cause my horses love to test them regularly
Agreed, absolutely not something load bearing. It would float and so would the wood. There may be a place for this product ( Home Depot) holding up signs that have been mounted in a 5 gallon bucket. But, not close to any of my projects.
Well I have seen it all now! A bag of post fix/ pour some water over.. job done ! Expandy foam for a fence , no thank you .. and anything that can be trimmed with a knife is not as strong as concrete, simple fact! I would t want to be the fencer who gets called the night after a gale force wind as IMO this will most definatelly fail.
Some things work just fine and concrete/ postfix is one of them . Definatelly aimed at the DIY market
I have seen Power companies use a foam similar to this when they set power poles
I did not have a good experience using this product. I used it for a basketball goal. First bag didn’t expand like it should’ve(yes I mixed it well). Ended up having to use a total of 3 bags for a total of $60. We had a night with high winds and it ended up coming out of the ground. Power companies may use something similar but it ain’t this product. It’s not quicker and it’s not easier than dry set concrete. It’s just easier to carry. For $5-$8 dollars a bag use concrete.
Rush idiots. Buy it ASAP.
The same company “SIKA” supplied the compound that Holden(the Australian arm of GM) attached by gluing the structural firewall into the VN and later Commodores, in the early 90s the trade erupted into turmoil, ” it won’t last”, “it’s not safe”, cars need to be welded anything else is ridiculous/stupid/criminal”, etc
Anyway… It worked… Is now used across the Industry & loved by many in the trade gluing cars back together rather than welding dissimilar metals and hard to get to joints etc.
Sorry guys, the future is here & now it’s gone, get used to it, in ten or twenty years y’all will be using foam/polymer house foundations and most likely it’ll probably be an effective sink for waste/recycled polymer stock too.
I used this to set a few fence posts. I was hopeful, but a couple of weeks later noticed that some posts were loose. Will definitely go back to concrete after my experience with it.
If you’re not getting the benefit of heavy cement anchoring the bottom of the post, why not just fill it back in with dirt and tamp. That’s gotta be better than foam that costs extra.
Have not read all comments, sorry if I am repeating anything.
1. I have never seen anyone use 135 lbs of concrete for a post, even larger ones.
2. Anyone that thinks of the environment would probably use concrete.
3. Costs difference is ridiculous.
4. With a post of correct length and hole depth, neither would be needed.
5. This looks like an answer to a question no one is asking.
The last thing we need in our life environment is more plastic!
I haven’t read the background info, admittedly….is it not made of Recycled plastic?
That was an assumption on my part.
But what about any excess once the hole is filled? Can it be mixed outside the bag for amounts needed.
I live in Liverpool UK is this available in UK it so
Were I need this to put up a new fence by my self
This would be FANTASTIC
MANY THANKS
Utility companies have been using expanding foam forever, on power line poles.
I bought four gallons of this stuff. Yes I was a sucker!! I used it on two corner post to start my project. This product was too messy, nothing like you see in the video, and it could be torn apart by hand. And yes I followed the instructions and used the proper amounts. I had to remove the post, clean them up and use concrete. If anyone wants this stuff I’ll gladly give you mine just to get rid of it. Buyers beware!!!!!!!!
Fantastic
As a handyman around the home this product is invaluable to me. Thankyou.
This crap made a mess! Bag broke when I rolled it. Went all over my concrete.. can’t clean it off.
Makes one hell of a mess
If building a two story pole barn, would this product be able to deal with the weight? How sturdy and stable would it be?
If you can cut it away with a knife how can it hold anything securely
Hi can I find this material in Malta please
Who sells it
Will never replace quick-set concrete mix on performance and price.
Like selling ice to the Eskimos…
Road construction companies use foam when building new highways and interstates. I use expanding foam underground in a coal mine to secure solid concrete block walls. And these walls can be up to 18’wide x 18’tall. Seals off unwanted airflow and holds the wall upright.
Where can I get this stuff? What’s the name if you know? Thanks I have a project that I need something strong like ur describing.
just let me tell you how comforting f’ing FOAM will be when what stands between your HOUSE and hundred mile an hour wind it a couple posts and fence sections set in it.
NOT.
Another non-biodegradable, non-recyclable material. What happens when you remove the post? The seeing material can’t be reused like concrete. The day has come when we have to go back to reusable methods. No one will take our garbage anymore. Polyresins don’t degrade. They just become landfill. The engineers need to stop with these quick methods that are leading to long-term issues.
Thank you for commenting on this joke. The part where the man is hanging on the post, that is about as false as you can get.
As a carpenter, I’ve used A LOT of products including Sika and this is a winner! I will be trying this out (if my Lowe’s carries it) soon!
I am raising a 2” PVC to use to hang bird feeders. I saw this product and was debating buying it. I couldn’t find it on the web site, looked under “Sika Post Fix” and ‘Cement Substitute.”
I wanted to know what the price was, if this product was biodegradable, does it lose it’s waterproof ability if it is cut with a knife, etc…
Needless to say, after reading these comments, I will stick with using Quick-Crete – the “old standard.”
If your theory about it floating in floods proves true, and our roads, power poles, and buildings are secured with it, what is next? Not biodegradable either?
Not used I well published when I use it
Such a cool product!
