Something didn't quite go to plan when this concrete was laid

If you want to lay concrete in the future I'd suggest watching this 24 second long video will help you get a better finish on your concrete.

Concrete pour.... when we did our double garage slab five years ago I put in two layers of mesh, supported on Meshmen.

The Meshmen were made of cement.

When the concrete pump started sending the mix, the Meshmen which had the same specific gravity as the mix, started floating. And the mesh went all over the place.
Grrrr

I assume (hope) that the concrete base was prepared to lay down other paving or similar? So not much harm done.

However, it has reminded me to keep my old air rifle well oiled! ;)

PS The rifle is probably so rusty and decayed that the pigeon would die laughing!

Precast concrete path edgings broken up laid on their side give 50mm cover and no floating

That's brilliant!

Last pour I helped at was only about 6 tonne around a swimming pool
- but my cheapskate mate didn't book a truck with a hose
- so it was an "it's a knockout" nightmare with 3 of us and old wheelbarrows for the last 10 metres - could barely lift a beer afterwards

as it was the order was also a fair bit short - completed with 20kg bags mixed by hand (and totally blowing any savings over getting the right bloody tool for the job! :evil: )

I also know of a perfectly poured house slab that was put on the wrong plot :roll:

My first concreting lay was a base for a conservatory at the back of our first house.
Terraced house with no rear access for a large vehicle.

Premix in three timed loads... I forget the qty but the base was 19 x 8ft with 6" slab and 36 x 18" perimeter, so it was quite a lot.

The load was dropped on the tarmac verge of our suburban street and had to be barrowed in, up the garden path, up the wobbly plank, through the house, the hall the kitchen, down and across more wobbly planks, and tipped.
I also hired a vibrating poker which no doubt further improved the already overspecified slab, but added more time.

The second load arrived long before the first load had been cleared. The third load ditto. The job which had begun at 0800h and had as its labour force me, and me... continued long into the evening. Then the verge had to be hosed down. Oh, and I ordered too much.
On the bright side, it wasn't raining.

We moved house and I never did build the conservatory. I understand the next owner built a two-storey extension on my slab.

Forget about Meshmen you want "strong boys"!

That's what my guys who I'd hired to take out my supporting walls and shore up prior to the steels being put in place said to me.

"Can you have 20 acrows and 10 strong boys here for us next week"

I had asked my rugby playing son if he could get some of his mates round before I realised that it was 10 of these I needed.

You'll need three resin anchors, a key grip, and a dubbing mixer

Ha. the instruction "Simply hammer the blade into a raked mortar joint and support it with a steel prop while you remove the masonry beneath" has the air of Haynes workshop manuals "simply rotate anticlockwise to remove", translation "this is going to skin your knuckles..."

Indeed...this was an incredibly sphincter tightening job where two right angle walls were removed leaving the upper floor of the rear of our house dangling on strong boys and acrows.

I used to know the publishing director from Haynes, a long time ago. They were well aware of the breath-stopping potential of lines such as "reassembly of the gearbox (or dashboard, or whatever) is the reverse of disassembly", or "finally, extract the hub using the specialist spigot alignment tool which is available on order from Jaguar". (Or, these days I imagine, "contact a Honda dealer to have brake tolerances reset by the CPU".

My friend's favourite was "heat motorcycle to 180 degrees and rotate anti-clockwise", which might or might not have been intended in jest. But he was emphatic about one thing. People didn't buy Haynes manuals so that they could repair their cars, he said. They bought them so that they could argue with their garages. Smart observation. :)
