It does happen occasionally…
I am currently trying to help some people find a way to get pipe under an 8 m wide driveway with access from one side only. It is proving difficult.
With access from both sides you can clear a path, but meet in the middle but with access from just one side it is much more difficult.
I have managed to plunk 5m in, but after that it just gets stuck and with poor water pressure we are struggling to keep the pipe moving. Plunking is normally pretty straight forward but it helps if you have good water pressure and can come at the driveway from both sides.
I explored some options today, one of which was the ‘bullet-mole‘, a piece of steel you smack thru with a sledgehammer. It looks like a great option, but unfortunately it can only go 6m and I need one that can do 8… but it does look like a great option for people who have narrower driveways and are needing to get thru.
The other option seems to be compressed air. I haven’t done this before so I’m reluctant to try it unless I am sure it will work, but it seems this may be where we land up.
