Us in Canada pour concrete footings for decks with no post in the ground, and then a bracket with a post is anchoured to the footing. Depending on the deck, you could have piles of snow sitting against the wood post all winter, which isn't ideal. Also, if the post every rots out, it's easier to change out the post if it isn't embedded into the ground. This also means we are not having to brace posts when we pour footing for decks, which makes life a little easier. For a fence mind you, we do it like everybody else sink the post into the ground with some concrete, need that for lateral stability anyway.

Ireland here, we dig out and pour concrete foundations/footings and fit the weed barrier membrane, the trend lately is to use adjustable decking pedestal risers made from recycled plastic set on the concrete-the odd fixing if even required as the weight of the deck means its not going anywhere. The plastic risers are great when you live in a climate where the ground is as wet as an otters pocket 6+ months of the year.

I want one of those undo mallets. Sometimes the normal one overdoes it.

[@Major-Dan]

Not just in the "States" ;-) The principle issue I can see with embedding chemically treated wood into the ground is leeching of those chemicals into the soil. Don't do it near your vegetable garden... In Canada, we pour a concrete tube and using a post bracket, keep the post above the soil. Not a lot more concrete being used in this method and a lot less post. Clearly, climate is a big factor. We have freeze thaw cycles that can penetrate beyond 1.5 metres in some areas. PS. Love your videos. Seeing the difference in building codes, materials and methods are a great way to not just compare but we can learn from each other.

[@BSCequalBOS]

As Scott described how the posts are buried in concrete, I would not think that the posts will transfer any chemicals to the soil. But where I am from post brackets are most likely used as you mentioned.

[@Major-Dan]

@@BSCequalBOS I agree, it's quite likely not an issue, but I prefer to err on the side of caution and only suggest he keep them away from where he grows his veggies. PS. Concrete is not a moisture block. It will delay any moisture (including dissolved chemicals) but will not stop it.

[@josephdavis8017]

As deck builder too in Canada (and watching the annual ground freeze & thaw cycles take place), I now much prefer setting my ACQ pressure lumber posts on top of the concrete posts with metal connector plates. Me thinks the Simpson Strong-Tie company is doing well now.

How do these concrete post perform in earthquakes. ? We sit on the boundary between two tectonic plates and earthquakes are frequent .

[@mrfusion99]

We use the same wood for building our raised garden beds without any issues.

[@doofusmaguilacutee4998]

Crazy Mate! In California, we don't embed wood in concrete below grade for anything (the building code doesn't allow it). With so much of the soil having a higher clay content that retains water, the "higher end" custom home builders will place some gravel in the bottom of the hole & pour concrete around the rest of the way on fence posts otherwise the post (even pressure treated ones) will rot out usually just below the ground level; for deck posts, the wooden posts are attached to precast concrete piers with Simpson Strong-Tie hardware and the piers are "wet-set" into a poured in place concrete pier.

[@pauls4708]

these posts will not rot.They are treated to H5. H6 is marine grade treatent. As Scott says we can build houses withH5. Certailn piles are buried deeper because they will form the bracing in the subfloor because we have high wids and earthquakes here

[@RoyMulder]

Canadian here. We have hollow pvc tapered tubes that can be used as deck supports (product name is Sonatubes). You put them all at the same rough level in dug holes, then bury around them with dirt. Then you can laser level all of the tubes and cut the difference off with a skill saw. The tubes are then ready to pour cement in the hollow tubes.The tubes are tapered because in Canada where it is cold, the frost can push up just regular posts. I built a 2 container/hybrid home and placed them on 6 sonatubes per container.

In Australia we have used round iron bark power pole posts as stumps set in concrete. The bearer is rested on the top of the stump with an ant cap and tied in with bracket bolted to the bearer and side of the stump. I also like using adjustable galvanized stirrups to help get a marginal fall in the deck away from the house for better drainage of storm water.

A day with a new Scott Brown video is always a good day 👌 We don't use treated Timber in Germany, so we use zinc coated metal braces in various shapes that we screw onto the post and then either anchor them on top of the foundation or pour concrete around them. They also allow you to raise the post above groundlevel so the wood is protected from spray when it's raining

[@21sheik]

Same in serbia, malta and greece, guess its a european thing 😁

[@dozaroner642]

How does the timver and zinc stand up to the weather conditions. Just curious cause here that would fall apart in a few months

[@SovereignStorm]

@@dozaroner642 depending on the species of tree, any further protective coating, the quality of your hardware (you can also get stainless steel for corrosive environments) and the effort you put in for maintenance, I would say something from 15 to 50 years in most cases

[@rainerl-h259]

Yes. We call it "structural wood protection" to make shure, that the wood will not be in contact with water, and, if it will happen, that the wood can dry fast.

[@mikerichardson415]

Posts direct in the ground also provide resistance to sideways pressure and minimise further bracing requirements. They work well in New Zealand!

[@rpaasse6453]

In the Netherlands to.

[@Major-Dan]

The issue is not in whether the wood provides structural integrity, it is that CCA leeches into the soil and can be absorbed by plants. CCA is no longer used in residential construction in Canada, since 2003. If New Zealand still allows it, go ahead.

[@muzzthegreat]

I did a bit of building-work in Queensland, where I live; and tens of thousands of houses have local-species of hardwood 'stump' directly into the dirt, no concrete, nothing. Stumps are often more than 1.5metres in, to provide bracing. Many of those houses are now 70+ years old, and plenty are 100+ Often a house needs one or two stumps replaced after 50 years. The replacement - where visible from the street [to maintain "character'] - is usually a CCA treated hardwood pole [typically a power-pole] into concrete, little metal termite-cap on the top. Replacements where not-visible [such as the second row] are often steel, for convenience, ease and price.

The piles here are pretty high rated H4 hence why the old school CCA treatment. Most fences are made with H3 treated timber and interior timberwork normally H2. H2 is the bright pink timber you houses framed with :P

I've used a multitude of methods to install posts for both decks and pergola's...stirrups embedded, posts embedded, brackets fastened or embedded into the footings...all work well, and I think it's up to personal preference...unless your Codes dictate the post installment method...i.e. high wind loadings for pergola's, but whenever I@ve embedded posts into footings...have ALWAYS wrapped them in plastic and taped edges/seams, cut the plastic off at footing level...then run a small bead of silicone around it to prevent water ingress...can then hide the footing/post with whatever floats your boat...works a treat everytime...and unlike our Canadian/US/UK commenters...never have the snow issue to worry about here 😁😁😁😁

As many other comments have stated, I typically pour a concrete footing with a metal bracket above the surface to accept to post (Canada). In the past I did use an additional product that could/should make the method Scott used last forever. You drill a hole in the post, drop in a pellet that dissolves and leaches when moisture reaches it, and prevents rot. The hole is capped with a removable plug so new pellets can be added every 5 or 10 years. It is common to see these in utility poles I’ve noticed as well.

[@mattv5281]

They sell extensions, so you can go as deep as you want, but it will be more work to clear the dirt out of the hole as it gets deeper. I think the widest auger is 8 inch (200mm), but in hard soil you probably don't want to go that large. And if you have lots of 48 inch holes to do this probably isn't the right tool anyway.

Seeing as you're drilling into the ground, ever thought of using ground screws instead of wooden posts? I've used them recently to build a deck. Easy to install, super strong but probably more expensive.

Hollow ground screws then stick reo down the hollow center and pour in concrete - what they had to go in my mate's warehouse/workshop built over really wet bottomless sand. Should be good for a lifetime or two.

Really enjoying watching this deck being built. Would love more videos though!

While we are talking digging, the carbide pruning blades are amazing for cutting roots out. I usually end up breaking the blade attachment off before the blades are dull.

In the ground with concrete works for us in Oz. First time I have seen 'Stools' that big. My experience has been coffee cup size to support Reo bar. You did well to get the holes dug with the battery power auger. I have the 18v Ryobi which does about four holes. But have plenty of batteries. 😎

[@subbasebuildingtechnologie6897]

yes those 'stools' are SubBase125's - SubBase also make the Subbase100 which has signoff for using 90x90 H% piles for residential timber decks !!

Concrete posts are what I'm familiar with. Empty tube, and fill it with concrete.

[@marekogarek6329]

I prefer putting wood on top of the poured concrete, above ground level (using the metal holders you drop in before concrete hardens). Less likely to rot, easier to replace if it does.

This was great!

Always interesting to see how construction is done outside of the US. I don't think we even use CCA here any more, as I thought it was phased out years ago.

[@chad3601]

Crazy how shallow the posts can be without freezing temperatures or a frost line

[@mcyclonegt]

We get so much rain where I live the post just rots out if you encase it like that. No matter the chemicals. We don't use concrete anymore, just crushed rock. Works great. All depends on your climate I guess.

[@anderw2]

In Minnesota footings are all concrete, but they also have to be 6 feet deep, to be below the frost line. If they were less deep than that the frost heaves in the spring will lift and break up your foundation.

I wasn't sure what you meant by Americans wondering why you put timber in concrete, they LOVE doing it. In Australia we don't do it, the standard procedure is putting a steel stirrup in the concrete then mounting the timber to the stirrup

[@robh.8214]

CCA is outlawed here in Canada. We only have access to ACQ locally. ACQ is effectively a crap ton of aqueous copper and is crap compared to ACQ which is not rated for direct burial or fixation in concrete….

[@vary8114]

I can't believe how good that laser showed up. I have a nice bosch and any sun and I can't see it. I've made tents and shade so I though

[@ardynottle]

Always love a build project. Good onya guys👍👍

[@tslee8236]

You can sit the posts on top of concrete blocks without digging holes. The deck is not that high. It makes sense to do it the way you do if you are putting up a cover on top and you need to anchor it.
