and then it rained and washed the lot away :;):

in seriousness it is fantastic work but i worry about arches built without any mortar

1 slip and the lot is gone

awesome find Giles

Luke De Col does say as an answer to one of the many questions that "there are pretty big footing stones in there about 8inches below the water level

dry stone walling has been constructed this way for many thousands of years, what the difference with his arch, why would this bridge not stand the test of time when other dry stone structures have without the use of mortar ?

WOW I think that is spectacular. I would be so proud of it if I did it. I don't think it will ever collapse. The forces holding it together are huge.

Worked for the Egyptians......

I'm guessing now, not being a dry stoner, of the type you think, that it will fuse more and more over time as bits of grit get in and gum it up a bit?

Ball park figure on getting something like that done?

[GB_Groundworks]

decent waller £120-£150 a day depending on how far south you are

stone and flags £400 max

timber for form work £40

2-3 days for an experienced guy i reckon

I did wonder how he was going to buttress it then by the end, there was no doubt what was supporting it. Great bit of work and history

2-3 days giles?
I reckon more like a week
not knocking it but to my mind wouldnt have hurt putting some strong mortar in their
the Egyptians built pyramids but never arches

it is a thing of beauty but I still wonder about is longevity

It's only 600mm wide arch think i could do it in 3 days and my dey stone work is limited

Ill copy some photos a Norwegian member of the digger forum posted on this same subject, think it was from the 1800's (oops)

I heard on radio 4 today that the accrington brick works made the bricks for the Empire State Building foundations. There famous nori or iron but they made the reverse brick mould wrong

So you're saying worse case scenarion 890. I'd be very happy if I paid 890 to have that in my garden. I'd be happy if I had a garden but you get the idea.

I agree it wouldn't hurt to hide some mortar in there but in my totally unprofessional opinion I think that'll hold for a long time.

I'm south and I reckon you could sell that as a job at £1200 (at least) and rich people would pay it and be happy.
