Are you mixing concrete by hand or mixer , don’t mix by hand  electric mixer hire cheep as chips and easy on the back , 👍

Well it will be done by hand as my next door neighbour who's a plumber by trade and just quite recently done up his entire house by himself seems to find filling the hole an hour worth of a job trust me when i say this, he's no ordinary human

I ordered 10 packs of 16mm studs and capsules from Screwfix, they were the Rawelplug ones.

I dropped the capsules into the holes, banged the studs in with a heavy hammer, then used the driving socket provided with the studs to drive them in further using an ordinary cordless drill.

The 18 mm holes were drilled with my 1500 watt sds drill and a long bit. I had to grip the motor between my knees and put my whole weight on the drill with both hands.

wowzer! that must've taken some force to drill the hole in. I reckon i will end up doing just that given i can't seen to get the threaded rods bent. They are a massive chunk for sure

I found the easiest way to bend rod was drill a hole in an old council path to depth needed   insert , then use a lump hammer and a bit of 4x2  bend to suit

What size threaded rods did you try bending?

It would be really neat if you could put something into the concrete to pre-form the holes rather than having to drill them.  Can't think of anything that would work off the top of my head though.

The guy from my facilities department at work did suggest something, not sure how practical and better it would be but what he said that put the concrete up to say 2 feet and then let that bit cure. Once cured, drill 4 holes and place the bolts inside of them making sure i have enough of the studs length above the top of the concrete which will then be filled with the second pour. This means it will not be a single piece of concrete but two pours but not sure if both pours when done at different times would be as strong as one pour.

I really had to read that twice to make sure what you meant Dave #Akward lol

By the way, just found something on Youtube which might have the potential of bending it without much hassle. Let me know what you think

Always more than one way to skin a cat I'm OK I've got Oxy Acetylene.

Big vice and big hammer will bend stud but I wouldn't bother, just making work.

Dave is probably right - your studs are 30cm long and you would bury 20cm of it in the concrete. That is probably enough to hold without needing any of the extra things we have been discussing...

I would still try and put a bend on them; I am surprised your aintenance department doesn't have access to some heat, a big vice and hammer... I am guessing from what you said they work with big pipes and they must sometimes need slight adjustment to fit...

But if you do put them in straight, then allow the concrete a week to harden and gain strength before trying to pull down the pier on them. Just in case...

Good luck Saturday,

Gordon.

We've used resin to fix studs into concrete ceilings to support trays for electric cables etc which weigh a considerable amount plus we had a habit of swinging on them to hop from one scaffold tower to another, only 6mm studs I think drilled in about 3 inches.

I'm not sure what they have to be honest but by the sounds of it they don't have anything that would help me bend the rods so back to another plan. I can also look in to welding some smaller rods or fins perpendicular to the M16 rod OR try and sacrifice a rod (i've got 5 of them) and see if the above video might do the trick OR last resort use resin.

I won't be looking to put the pier on the top of the concrete for a good week and a half or 2 weeks if that is at all recommended.

I used m12 rod if memory serves me well and 16mm holes in pier plate ,

Nice one. Do you have a detailed thread here that i can pinch some ideas from? How did you suspend the template without getting the rods getting fully submerged in the concrete? i see some blocks of some sort around the base, can't make out what that is.

Another question, since i've only dug the hole so far, do i need to make some sort of a wooden brace around the top of the hole to keep the concrete in a perfect square or whatever one uses it for?

I will find my thread this evening, click on pics to go to my Flickr there are other photos on there .

Hi Ahmed,

if it helps you for Saturday, I had some sand delivered lunchtimee todasy for my terrace work... 1.95 tons, in a big trailer... It's mid-30's here and humid and we* had to unload into buckets and transfer it to the worksite...

Took all afternoon, but it is considerably more than you will have to deal with, so as your plumber buddy next door says, it should be OK.

* normally this would be a BLUE job, but as I could not really do this on my own, I managed to persuade Mrs Bukko to help. Bless her.

Anyway, good luck on Satgurday, looking forward to the pix.

Gordon.

Ahmed,

Forgive me saying it, but as @Davey-T KISS, you are by far over complicating a very simple thing, its not rocket science nor need much specialised thinking, simple Summary: -

1. Dig Hole
2. Fill with Concrete
3. Drill and bolt pier in with Epoxy
4. Use and forget

With the greatest respect Ahmed, 8 pages to summarise the above, it really is a very simple project, no real brain power needed.

Just use and enjoy!

No offence!

None taken  yes I might be over complicating things but as i said from the beginning, i lack the skills and knowledge so asking for help and it is preparing me for any eventualities. Better to be safe than sorry.

Yes it's 8 pages but 8 pages full of information which might be simple things for many but that's all new information to me and help me understand things and see them better

I used 1m long M14 threaded rods in my concrete pier (poured in one go with the base) which I was able to bend without too much trouble.

Yeah i suppose you do get some sort of a leverage to pull the rods of that length easily. Unfortunately the studs i've got are only 30cm long

Top top man. Cheers for that mate. I'll take a look now

[souls33k3r]

So using the KISS terminology, i've decided to pour in the concrete without any template, level it and then drill the holes later. 

Concrete will be poured on Sunday it seems as my next door neighbour has some things to do tomorrow but all in all, things will be moving forward this weekend. 

Will update with pictures once i take them

[Jkulin]

Ahmed, the only thing I would suggest you do to make things easy it to build a square top frame as that makes things so much easier to get level, and once done won't need any correction.
