Composite decking, base installation

- Not posted in a while as we are expanding and its taking a bit of leg work. We are fitting a composite deck to this build and in this one we fit the base out of 4x2 tanalised, 4x4 treated posts to support, the holes are filled with post crete, we then put a black weed membrane over the top of the 4x2 to create a black shadow gap when the composite decking is fit.

I am learning so much from these videos, even though I do have a trade background but that was years ago.
Nice to see you again, doing excellent work as usual. Take care and stay safe to all.
I was having withdrawal symptoms Liam...welcome back.another great vid mate and looking forward to seeing the metal sheet installation.Cracking job as always
Looks brilliant already
Can't wait for the next one! 👌👍
Nice work you doing there. Your jobs are quality.
Love the way he makes it sound so easy.
The detail for the shadow gap is exceptional!
Why not use bitumen black paint instead?
Quality job mate. Good team you’ve got there.
Every time I watch one of your videos I am truly baffled how anyone can 'dislike' it or leave negative reviews. Mental. Looks cracking as always mate, great to have your videos back!
I’m perplexed as to why fix a composite decking on a wooden frame which will eventually rot. Surely you would use plastic of concrete into the ground. I’m not disliking the video it just seems questionable as to the choice of materials. What are your thoughts??
@@donaldtriumph1682 Treated, membrane, air gaps. the answer is in the design.
@@JamesT65 yeah get all that but plastic wood would be for life. Wood will always rot eventually??
@@donaldtriumph1682 maybe the clients choice but otherwise I'd agree.

Love the video mate. You come across really well, friendly and informative 👍
Thanks mate
Hi mate. I did a deck about 15 years ago using 4x4 posts concreted in as you do. I recently changed the timber deck for a composite one and everything was sound below with no rot. . Great work again.
This will be another excellent build.
Quality theese videos pal keep them coming
Another great job. Still baffles me when people try and give you negative feedback. Does every house builder build a house the exact same way?! Suppose the negative feedback are from people trying to bigup themselves. Keep up with the good work guys.
Big up themselves, what nonsense 🙄 the fact that putting composite decking on a wooden frame is the reason why.
Again amazing free information. Now I can redo my decking properly. Thanks
Dont do your posts like this they will rot in a few years
@@tyler4164 then I will have had the experience to redo them. As a non DIY person I need the experience. Plus chances are my wife will want a different type of decking, so in a few years I change it.
25k subscribers, congratulations!!!
another great video with priceless info.
Welcome back keep them coming
Can't fault any of your work, good job!!
But people remember, your making a lovely little "home" for uninvited guests!!
Any chance of a video showing how you do the electrics, spotlights, fuse board etc.?
Great video and just what I needed to know. Can I ask please what you used on top of the joists?
Great content again.
Great video, thanks for that. Genuine question, as the decking is connected to the garden room, does the size of the decking get summed up with the garden room or each one is treated as 2 separate constructions in terms of permitted development?
I literally looked up your youtube channel to see if there were any new videos 8 minutes ago. what are the chances!
like the way you put black membrane on top base wood
U are fantastic sir
Always wondered what’s involved in decking! Thanks
Genuinely you’re the only guy I see building the quality you would for yourself. Well done. Love your videos
Hey man I’m about to build a deck for my cousin, if you could help me with advice that would be awesome, only thing I’m not sure of is the posts what exactly is the deal with the posts I’ve seen a few different methods. Do you put gravel or hardcore underneath or do you allow the post mix to go underneath to prevent sinking. Or is this not an issue with enough posts. Cheers mate rate the builds.
Did you allow any gradient to the decking for water run off ? - not built with composite decking yet - wood a few times over the years - any issues with grip / pooling ?
Good stuff boss
Did u do the the fencing or buy it , like to copy this ,just the job for winds.
How do you attach your noggins in a straight line, I've always seen them staggered and screwed from either side, your way looks much neater but can't work out how you have fixed them to the frame? Are you using a jig to go in through the cheek?
What is that connector block in the electrical wiring? Would that not give issues later on?
Legend.
Did you create a fall on the deck for water run off or install it level ? Just curious, I thought that you were supposed to create a fall. Not being negative, just curious and keen to learn. Great video and channel - new sub !
I am about to do the same with 4x2 and 4x4 posts, what can you recommend for the spacing of the 4x4 posts? thanks
What tape is it you've used on the joists there? And where did you get it from? Looks like another cracking build. Thanks
looks like damp proof course. All builders merchants stock it
would love to see how you do the metal sheeting on the back, need to add this to the back of my build
CharlieChapling tomorrow!
@@thegardenroomguru do yo have w Instagram
Are 4x2 boards strong enough for the under frame?
Can I just ask is composite deck as lethal as normal decking when wet?
Hi how many post do you put in the ground and is this the same for a composite frame please
What protects the top of the support post?
People nick picking on what what do different. Just RUclips bells. It just shows you're doing amazing job because they can only pick petty shit. Your builds are as sound as you'll get. So be grateful just wasters picking something or nothings
Excellent! Woodworking with a chainsaw, now why didn't I think of that?
Did a full composite build earlier in the year, not got the video up yet (Edit: it's on my channel now). The composite joists were crazy to work with, so much flex and expansion in the slightest bit of sunshine. If I did it again I’d do a timber base. And responding to those who are commenting on the longevity of timber - the composite deck replaced a 20 year old timber deck. And the joists from the timber deck got re-used on a second timber deck. And it was just tantalised timber, nothing else. It originally stood on wooden posts on pieces of paving slab with just a square of dpm under. Not so different to what’s shown here.
I couldn't agree more about the plastic 'lumber' it is an absolute b*tch to work with. It kills your tools, everything from drill bits to TCT blades wrecked in seconds. The stuff I used wasn't even dimensionally consistent. It is man-made, at least they could get it the same size, and cut the ends square. I wouldn't use it again, but at least it will see me out.
@@nigel4425 Haha yeah I missed the damage to blades but I had exactly the same thought when I built mine, it’ll outlive me. I really must put the video together for it
Did one before Christmas using aluminium joists an adjustable feet .product called rhino deck .they were pretty much aluminium 3x2s but came with jointing brackets screws the lot .was a decent set up was quite impressed
Totally agree.
Just a quick question - is that frame only being supported by the screws in the posts?
Yes
Great work guys but I seriously hope the Heath & Safety Executive doesn't see the lack of the required personal protection with the chainsaw usage. I've seen many very large fines issued for less than this. Keep safe boys.
this is addictive viewing get on to sponsors paslo milwaukee dewalt ect ...PS..can you smile more it brightens my day Liam
😁
Could 4x1 be used for the frame?
Anyone got any advice on building a raised composite decking on top of an existing patio? It is very solid so I didn't see the point in digging it up, was just going to put a membrane on the end of the posts and set them on the flags. It's going to be raised about 400mm above ground.
Perhaps you could use 4x4 bolt down post supports if the slab is solid and you can fix to
Why is there no follow up video to this with the finished composite decking fitted??
I'm not being abrupt in anyway just curious as to why a composite decking would be held up by wood?
it's how it's done in the UK don't ask . you can get composite framework but it gets real expensive
The wood below won’t need maintaining. Wood for the deck would.
sir would like to know where can i get hold of these fence panels
How deep do the posts that are throughout the middle need to be into the ground? Do they need to be the same depth as the outside posts?
Yes & no really….they’re just to take the bounce out so you can get away with a little bit shallower if the digging is difficult
Hey man what brand of pants are those I'm looking for more durable work gear
Did you say last chance to buy a build pack is on Friday mate ?
No mate, last chance to get them at the sale price
What do you do with all your cut ends? Didn't see any treatment on them.
Do you ever use anything like bitumen paint to lengthen the life of the wood?
Its time consuming but keeps the wood from rotting early. Especially in a sunny Scottish back garden. 😂
used motor oil and diesel 50 /50 mix works a treat.
@@SteveZussou agreed, not environmentally friendly but as a wood preserver it lasts!
Just curious! Why not the same footings as the garden rooms (eg threaded studs)?
the 4x2 will last along as the 4x4, so threaded bar would outlast it all, no need for a deck mate
If done right decking can last for years. I know this as i recently removed my raised decking & the timber was still like brandnew after 13+ years. Only reason it was removed was we wanted a patio instead
@@thegardenroomguru Just about to start ordering the base for a new garden room, a new workshop and some decking. I was going to use the threaded rods all round, along with UC4 timber for a bit more longevity on the base.
I might be barking up the wrong tree, but my previous deck frame (c24 150x50 UC3, and UC4 100x100 posts) only lasted 13 years before starting to fail in certain high moisture areas... the wife was not too happy!
If I understand your reply above Liam, I may be wasting my time doing the whole thing with rods and UC4?
Do you think I would be just as well using 100x100 posts for all of the base, including the garden room and workshop, if the timber on the base is still the weakest link and will rot at the same rate as the posts anyway??
Hi William I have watched all your videos and have mirrored your garden buildings . I’m very happy with the result only I’m experiencing some condensation on my Bifolds (no trickle vents) what could be causing this? Do you get this? Have I done something wrong? 🤷🏼♂️ please help
PF trader01 we have trickle vents, but due to the insulation you do get condensation on the doors and glass as the internal air temp is higher than the external and as cold meets warm you get condensation, leave the heater on at a low 18 degree
@@thegardenroomguru i am about to install aircon wonder I that will resolve? Failing that i may need a heat recovery system? Thanks for the reply 😁👍🏻 also loving the deck video mixing it up!!!
@@pftrader0149 think this was just the plaster drying out. fixed within a few days and a dehumidifier
Can anyone recommend the best composite board for Uk weather. I’ve watched lots of vids but prefer personal opinion. Cheers
Do they need planning permission or required to meet a spec?
hope not because that decking wouldnt even pass lol
I have always been told not to fix 4x2 to the side of a post using screws, which are brittle and don't have good shear strength, and that the posts should be notched so the vertical load is taken by the timber post and not the screws. I have just finished a 50 sq m composite decking project and notched every post.
Thoughts?
150mm screws ain’t breaking
@@thegardenroomguru 😅🤣😂 No but the wood will be a ROTTING!
COMPOSITE DECK on wooden subframe 😅🤣😂
@@robertday8619 pressure treated tanalised? lets put it this way it will probs out last the composite deck
@nigel, notching out the posts to support rails is good practice when supporting extremely heavy loads ie, a log cabin, big out house etc. You're right, using screws is bad practice when attaching a rail or joist to a post. M10 or M12 bolts paired diagonally from each other, however would be the best way to go for a simple deck supporting the weight of a good few people. Screws can shear, even bolts can shear which is why you would set them diagonally.
I would have shoulder cut the posts. Load is then supported by the post rather than rely on mechanical fixings to support the load. Certainly would not use screws due to weak sheer strength, coach bolts better option.
Looking at that thumbnail video you looked like you were re-enacting Bjorks video where she stands on the back of a lorry.
Composite decking on a wooden frame, MADNESS 🤣😂
What else would he use? As far I know there isn't a composite joist on the market and it's best practice to use a deck tape/membrane between joist and deck board. When a deck fails its rarely the joist that goes first.
The only other option is galvanized frames but big bucks
@@tedcopple101 I put recycled plastic joists under my composite decking, 4 X 2 can get them from several places now never rot.
We just recently took up a hardwood deck that had been down for 20 years. The sub frame had rotted in places but was still structurally sound. This was the old style treated timber too, with the red treatment on it. Bottom line is, we use c24 externally treated timber for our subframe when undergoing a composite decking install. As long as you have a decent airflow around it and you've constructed it solidly, it can last 20+years. We also use European grean oak for our concreted in posts which will also last 20+years under ground contact.
Oh, and as a side note, I would always do 350mm centres on the joists and not 400mm
👍👍👏👏
Where do you get your timber from I live in sheffield
Shire timber Leeds
Well done. Here in Australia I use treated timber as you've done, but also galvanised steel. We've a big problem with termites.
Should the joist not be recessed back into the 4x4 post so the weight is bearing on wood not screws which rust snap and losen.
No
@@thegardenroomguru 😉😉😉👏👏👏
Yes they should Stu.
@@ollydearden Recessed joists are essentially weaker.
@@patsavage1245 Rubbish.
Use the right timber, requisite carpentry skills and the correct fixings.
I like this guy but that deck will be knackered in fifteen years.
I'd personally not use timber for the posts. Guess budget dictates.
Paint the posts with black jack and they won't rot.
Wooden posts into the ground will only lead to disaster tantalise or not. Screws into the posts will lead to disaster.
I do like a good Northan accent how do I collect my nailer gun please
3:30 Good woman yourself!
Has it rotted yet?
no
@@thegardenroomguru Just banter 👍🤣
Odd, so they'll have almost zero garden left
No maintenance garden is a thing to cherish
You are meant to bank the concrete where it meets the post so the water will run off and not pool around the post. See Ultimate Handyman for demonstration.
It’s never going to pool, unless it’s Mississippi
Those posts will be rotten in no time. Seen plenty of decks built this way & the posts always rot at ground level.
@@tyler4164 how do you build them to stop the wood rotting?
Depends where you live....In frost prone areas the concrete should be several inches below ground level to prevent frost damage and heave.
Good that you are using tanalised timber not so good that you are not resealing the ends when you make cuts. Not doing so invalidates the guarantee on the timber!
Composite should always go on 6x2
Why
thats what is always specified by our suppliers, two much bounce on 4x2
thanxx not if you put enough supports in , m
@@thegardenroomguru eco dek wont warrant the product on anything less than 6x2
@@thegardenroomguru also by putting all them noggins in like that you are trapping moisture. what do you think them two lines on the back of the boards are for??
Not the way to do it posts in holes will rot laying course of blocks to sit in is better
@@leemurphy855 yes
Do not put membrane like this on your joists !!!…you will rot out your joists quicker….use deck tape…it’s specifically made for the job
Use decking tape , that weed membrane under the boards is a terrible idea
