Well after a busy Monday we now have 4 holes, which is more promising, though all 37-39m deep. So the definite plan is to go for 8 holes and we have the requisite extra pipework coming tomorrow.
My geologist Professor friend signs up to the 150M yr old blue-grey lias clays OK but the underlying creamy limestone containing the voids is not really what the UK geological map says. Next hole we will get him a sample!
They now hope to be away late Thursday if all goes well.
The big family party went well - we got 3 cars in the other drive section (with some care) and the other 9 or so cars used the road. Perfect weather anyway!
