London gem heist. Clean professional job with Core drill.
They used core drills, Hilti core drill to be exact , as they left it behind. Cored through the basement walls.
Those walls look to be about 4 feet thick? As a commenter notes: where's the rebar in the wall? All I see is one possible rebar end at the center of the cored hole. Like the below comment and agree with it as I got a Hilti combi-hammer ; Hilti stuff is top notch. "The next job should be sponsored by Hilti. Their equipment is top notch." Hatton Garden heist in pictures released by Scotland Yard | Daily Mail Online - So are the coppers going to make a fuss about seeing who buys Core Drills? Wouldn't surprise me what with how intrusive and nosy UK government is. |

Didn't see any rebar in that wall , it looked like mass concrete . Schoolboy error for the contractor who installed that . If the wall had rebar it would have took at least three times longer to core that out .

I assume it is not a load bearing wall as evident by the lack of rebar. It is odd to see a non-load bearing wall not made of cinder blocks, but of poured concrete. Maybee they thought a poured wall offered more security for the vault than a cinder block one, but if so why forgo the rebar?? I am neither a structural engineer nor a contractor so : Is it normal for a poured wall of that height not to crack when it does not have re-bar to add tensile strength? My hunch is the sheer thickness of the wall and it being only the height of 1 floor made tensile strength a non issue? |

Wall thick and big. Drill strong and bigger. Big hole.

Better than some of the concrete over here though. I reckon some of the older basement walls could be excavated with a rusty spoon.....

Re: London gem heist. Clean professional job with Core drill.
You guys can do beton than this surely. I mean, you lot are experts - at least the aggregate in here cements you all as the pinnacle of knowledge in such an area?
Just reinforce the point, I'm sure a few of you work with the composite, so must be able to mix some ideas together. That being said, don't get prestressed over it, maybe just think about it when you're at the rebar. |

Never mind. Everything will be better after 28 days...

Re: London gem heist. Clean professional job with Core drill.
I've slumped. But I've got some tests coming up in 7 days, then some more a week and three weeks later, by which time I'm hoping to be at full strength. Just hope I don't end up crushed...

Re: London gem heist. Clean professional job with Core drill.
According to news just in, over 200 officers have put their lives on hold over the past month to arrest 7 men aged between 49 and 76 in connection with the grooming of young girls by Asian men in Rotherham.
Oh, sorry, to recover some baubles. Rotherham carries on as normal... |
