In the past couple of days they've started drilling for real although it has been considerably slower than expected. I think this is partly because they've had a staff shortage due to the October week holiday, and partly because they had to go down 29 metres before hitting solid rock. This means that every three or four metres they have to stop and weld in another piece of pipe casing which goes down with the drill, slowing the whole process down significantly. Now that they have hit solid rock they're expecting it to be much faster.
The drill causes a bit of vibration and is a bit distracting while trying to work - not dissimilar to having a pneumatic drill nearby.
These are photos taken from the past couple of days.

29 metres???? Now I know your house is on a hillside, so wouldn't 29 metres of muck just slide away down to the rugby pitch???
ReplyDeleteIt was slightly surprising. We always assumed that being raised up a bit, it was more likely that the rock would be fairly near the surface. For the fourth hole (yes, really) they had to go even deeper before they hit the rock.
ReplyDeleteSo far the rugby pitch hasn't got any closer. I guess the 'muck' is pretty solid.
