Like all the videos you made about NYD. Good job. Well done

Me encantó mucho, felicidades amigos míos. Por su dedicación.

[@LimestoneCoastCustoms]

This is interesting. While I have actually poured concrete under water, the thought of mixing it with diving certainly throws in a different perspective (maybe I should have completed my dive ticket all those years ago 🤣🤣)

[@skullfire_9]

amazing!

[@eliseoguzman6939]

Interesting to see how concrete is done. Something different other than welding.

[@paulstonepaul879]

Looks like a very professionally run course.

Good job good diving

[@Eduardo22099]

Que aditivo usaron para el concreto? Les quedó muy bien

[@paulstonepaul879]

Just an idea I would have used 2 circular half shell with a 2 bolt flange etheir side sandbags to seal the outer side of the shutter.grease the inside of the shutter to stop it sticking to the concrete. After it sets remove shuter and reuse on next pile. Just trying to be helpful as I am a diver with over 30 years experience and I wish you all luck. stay safe! 2 sayings !. There are old divers and bold divers. But no old bold divers. 2. Any one can just jump in but no one can jump out!

Nice video again Ranna. I could not see it, but I suppose that there was a quater turn valve on the airlift?

[@rannarlaur]

Yes. The valve is there. I know it skipped the screen, but diver has the control over it ;)

[@josencleves100]

I'm a brazilian commercial diver and would like to do it.

[@zien123]

Good morning good job

[@superkeen2242]

I went there very good school

[@geert7128]

he Rannar, love the video.. i have to do similar works but and have some questions. the steel pipe is it like a funnel or is it connected to a flexibl hose? i it is do you use a concrete pump and what kind of pump it is ? thanks in advance.

[@rannarlaur]

The steel pipe is connected to a flexible hose which is connected to a pump (mixing and pumping). It was a very old pump... I guess from 20 years old... old and slow =) ...

[@gchqjtrig6492]

Portland cement?

[@kinggkongg9694]

Is it fondu???

[@hahahahahahahaha3241]

Hi Is there a PDF study for maintenance and cleaning ships and small marine boat

[@changrnpro4998]

Hi can portland cement use underwater about 2ft only

[@rdvlog0422]

What kind cement used for underwater?

[@cnfhabagat7062]

Regarding underwater fresh concrete pouring, is there added special chemical admixture used in the concrete to keep the concrete become cohesive?

[@rannarlaur]

The concrete powder itself was some special mixture (extra tuff and so on) and yes wed did add some chemical liquid, but it was for fluent flow (so it wouldn't get stuck during the pouring). Otherwise, time did the job... it took around one week to set, and then we could remove the casting..

[@cnfhabagat7062]

@@rannarlaur thanks for reply

[@eijijivjiv]

what kind of camara do u use underwater ????

[@rannarlaur]

GoPro7 Hero Black. At that time it was the newest Gopro there was ;)

[@tarabrown7399]
