RESIN ANCHOR BOLTS: What you need to know! 

A few ideas: you can use the exiting air from your vacuum cleaner to have an "airblower", helps with the cleaning of the holes. That or a compressor ofcourse, but I hate this hand-held pumps. Also, instead of the brush i use an 8mm steel rope - put it trough small pipe, about 10mm id. so you can hold it while it spins. Take one end of the steel rope and bend the wires outwards, so they act like a brush. Then put it trough the pipe and put the other end of the rope in a battery drill, then put it in REVERSE... boom, clean your hole with that. If you dont put it in reverse, it will untangle the rope, which is what you dont want. Another tip is to scoop the excess resin with your finger (wear a glove) and smear it onto the next bolt before you put it in. That way you save on some on the resin, and also you make sure the resin is well inbetween the threads. Oh did I mention to degrease the threaded rods? :) I use acetone, but most anything will do. You shouldnt skip that step, because they have a bit of oil on them from the factory. And always prime when you put on a new mixer. Good job by the way with the video, I loved it. Sorry for the comment, but I thought you might use some of the tips, like I'm gonna use some of yours! Good day sir!

Nothing arty farty with glamorous video recording here, plain simple professional demonstration... learnt something new today - thanks!

And tony is still there brushing them holes out ready for resin fixing lol 🔥🔫

good to see a building company not staffed by chancing yobbos. nicely done

very diligent in getting the dust out... makes sure for a strong bond... I will pay more attention to this as I have just this job coming up.. thanks for putting this up !

Excellent account - quality workmanship and attention to detail. Great to see! I wish A&E had done my extension - it wouldn’t have been the nightmare it was! Keep it up guys!

Nice well put together video lads! 9:35 - As the materials are not mixed in the tube though, every fresh go you have to prime. Hence why the material in the end was cream, as it hadn't mixed.

Thanks Tony keep the vids flowing. (awaiting next spiral staircase).

Okay, so... we see where the concrete has been chiseled out, the bottoms of each square hole pretty rough and uneven. the bottom plates of each steel column are spaced above the bottom of the square holes with the nuts for the threaded rods (obviously to keep them more-or-less upright, and to avoid contact with uncured resin). All well and good. Now: are those square holes partially filled with concrete to level the bottoms, before affixing the plates permanently to the foundation/slab? Or: what? If the bottom plates are fully fastened to the uneven bottoms of the square holes (with the nuts fully tightened), they won't stand upright, perfectly perpendicular to the slab. AND: none of those bolts are long enough to mount the plates above the actual slab, once the square holes are refilled with concrete to match the slab. Much time was alotted to showing each of the bolt holes being perfectly cleaned out. A single bolt hole would have sufficed to demonstrate the procedure. Unshown: how were these things all leveled and finally secured? I got the gist of the two-part resin being injected through the mixing tube (I've worked with lots of that stuff-- 1:1, 2:1, 10:1, etc...). But the base plates being leveled to the square whole bottoms was entirely omitted. Enquiring minds want to know!

I'm using steel brush used for cleaning copper pipes fixed in to battery drill plus compressed air. Power tools are so helpful.

thank you brother

Why do you not want the plate sticking to resin? I’m putting an SHS post in and I was going straight from base as post is never moving for my extension.

I use my Bostich compressor to blow out, hoover out also & I Pva the holes. Top work, followed this series in last few days, quality work from a fellow builder/ carpenter.

Some work involved in that job. Super job

Hi guys great videos loads of tips and tricks 👌💪💪here's one I cut the end of the bottle brush and and stick it in the drill works a treat 👍

Thanks for taking the time to make this video really helpfull

Interesting, informative and helpful. Good instructive video. Paul

Useful clip so thanks, makes the results a DIYer can achieve so much better.

Yes! Another vid!

Didn't see you putting on the spacer nuts under the baseplates - assuming these were critical to getting the final level of the stanchions right how did you go about this? Excellent detail - now't more important than the footings!

Nice graft mate just one thing -Tape some cardboard or something against any existing walls before pouring the footings -it saves a lot of cleaning after .really detailed and great video 👌👌

Craftsmen at work...loved.

Yep, there’s definitely no dust left in them holes

Great video Keep up the good work 😊

Thanks for the vid, very well explained ! You wouldn't want to get this process wrong as you could end up with a right ball ache on your hands.

Awesome video. One thing though is judging from the color, it looks like the resin in the tip wasn't fully mixed at 9:45 before it was put in the hole. I'm sure you already know, but a proper respirator and eye protection are good idea when working with that dust.

Thanks for this, you explained it really well. I'll be using the resin for the first time for a DIY project and this clear explanation really helps. How long do you have to work with the stud in the resin before it starts to go off?

great and thorough explanation. thanks

Professional job. Why don't you place oversize nuts over the screws to support the studs just underneath the bolting nuts? Otherwise, not placing these nuts but sitting the stud on the excess resin might be even better, in order to keep the stud at correct level after hardening.

Good work on the cleanout. I'm using some thick staws, just throw in the staw and use your hand as an adapter to the vacuum and then do the brushing and blowing. You can use one of the bolts to smear the excess so you do not need to touch it with your bare skin, this stuff is nasty while wet. Also you do not need to use a new nozel beween cartriges.

Very interesting. Not easy. One question. Why the extra concrete cuts in line with wall. The extra slices in the square perimeter???????

Great video guys very neat job

Wouldn’t it be better to just lay a piece of paper under the plate instead of those nuts to prevent the plate from sticking to the resin? Don’t the nuts make the platform weaker as it’s not fully resting in the concrete below? When you tighten the nuts on the rod doesn’t it bend the flange corners down because of the nuts under the plate? Can those nut rust? I’m not a contractor, I’m just wondering.

Great attention to detail! Clean and tidy site! It’s a joy to watch you guys!! Got any jobs?

Cracking video.

Quality boys

What a carry on to get a fixing a Rawlbolt or through bolt would have done similar, the base will be filled in later anyway.

Great I’ve got some really long studs to fit into concrete. Will do it this way thanks. Might have covered that window before you poured the concrete though.🙈

Great video…make sure you wash that finger 😂

I’m screwing brackets to hold my deck posts down to existing footings. The footings are over 20 yrs old. Can I use the resin with a concrete screw or is it just for studs? Are these special studs like stainless, galvanized or hardened?

You should made the openings bigger for grouting underneath the baseplate

Hi I am looking to build a window cannopy at front of house. However I am getting external wall insulation on my home in a few weeks. I have been advised to attach 6x2 C16 grade timber on the house where I want the cannopy frame to be prior to any external insulation being done. My question is what fixings / fasteners should I use for the 6x2 timber and how far apart should I position said fixings? The length of the cannopy will be 5m and will I need any supports underneath the cannopy? I'm thinking that some chemical fixed m12 screwed rod should do the job. But not 100% Thanks in advance.

Great

Tony,when I first saw the thumbnail for this video and seen the cut out in the footing, I thought uh oh somebody’s cocked the levels up,but then I thought about it did you use them as grout forms after bolting up the steels.

i would have though is you use a sucking tool to clean out the hole instead off a blowing tool you would get a much cleaner hole. you could cut the blower long thin tube of the blower and attach it to the vacuum cleaner to create a sucker, ( a bit like BORIS JOHNSTON), to clean out the hole. using the bottle brush would make this approach even better. maybe use it on BJ also. oh yeah BJ stands for something else too. haha

She didn't flash her ginger growler at them, I notice.

Silly question but I’ve never seen these metal studs before. What are you guys using them for??

Nice vid, if you want to use m12 bolt for the resin do you use m12 drill bit or the next size up? Thanks

What's the advantage using chemical fix rather than a concrete anchor bolt/screwbolt, stronger fixing?

Nice video, thanks! Do you use something like a structural grout underneath the metal posts when you ultimately bolted them in place?

Would you be able to screw out studding from the resin if you had to?

Do you think you could fill a hollow tube with that then screw into it with normal screws.

This obsession with brushing can't be healthy.

Definitely missed a spec of dust in hole number 3. Henry be like ffs lol

Have the hoover going while youre giving it the in and out. Save all that dust going in your lungs and also some time. Nice demo though.

Thank you very good video. What diameter of hole you need to drill for a 12 mm threaded rod? (What is the recommended gap, if any, between hole and threaded rod)?

Why do you need resin in solid concrete?

Why or did you ask engineer why resin bonded bolts rather than standard rawlbolts?

What a faf just to put resin in and cost hr

that stuff would be great for a gun cabinet thx guys

What is the purpose of these ‘steels’? Is there a link to their use....

What are these metal posts for?

v. good

This stuff gets off at no time at all. Really a nightmare.

Why fill the hole completely ? Surly it’s a waste of resin.

Don’t do not fill all the holes with resin - do one at a time because if it’s warm the resin will set before you put the fixing in

Christ! Talk about OTT with the repeated blowing, brushing and vacuuming! And what a waste of resin! Why not do one stud at a time initially until you get a feel for how much resin each hole needs without wasting it?!

Dentists use this stuff to fill holes in teeth 😉👍

Ughhhh VACUUM 🤪. Hoover is a brand. 🤡 Why don't you have the VACUUM running next to the hole as you are blowing the air out of the hole and using the brush?

Bit ott tbh

More talking than work

Poor home owner having to pay for all that faff! Yes, I do know what I'm talking about!
