".....We're slaves to what we're told. On Saturday we were told the above was a "wildest dream" scenario and you have now told us it's a worst case one. As i said, we intend to accept the account offered to us by EH on Saturday and will assume that the plan is to go in there without causing damage or enlargement."

You are reading and quoting from a Risk Assessment as I said before - you appear not to understand how to interpret the information, nor exactly what a risk assessment is nor what its for.

However you are happy on the one hand to use the information for your own stated aim of 'grouting' but not so happy when it appears that re-filling with chalk is by far the most stable solution for the Hill.

Which is what you've wanted all along isn't it?

I see know why Ishmael described you as 'ranting' on Saturday.

From the locked thread -
"We referred to it as a new tunnel because

First, EH's article in British Archaeology Jan 2005 [Appendix 5] said – "Atkinson's tunnel entrance would be re-opened and "a new tunnel constructed to the centre of the hill" "

From Britarch -
"Atkinson's tunnel entrance would be re-opened and a new tunnel constructed to the centre of the hill, <b>ideally wholly within the line of the original</b>. Then working outwards from the centre, the remaining collapse and infill material would be removed and all voids re-filled with properly compacted chalk."

Prefer to leave certain information out do you Mr Swift?

For the gaps in your knowledge, regarding your pet subject -

Slurry grouting - the engineer actually said no-one can predict what might happen if a slurry containing water was introduced into a 4000+ year old dry environment. One of the implications being that slurry might destabilise the structure.

Pressure grouting - rejected on the grounds that it was only normally done when you'd already created a sufficiently stable and strong structure.

With either method what you could not ensure was that all the voids would be filled.

Bye! Bye!

You can have your 'bat & ball' I'm off to enjoy the Vale of Pewsey (and Marden Henge), the Marlborough Downs (and Avebury) and Salisbury Plain (and Stonehenge) - its fabulous living around here. :-)
