Irrigation Pipe Under Driveway

[swisstoni]

My DIY installed irrigation system has been doing a good job but now I need to extend it under the gravel drive. This means trenching or tunneling the 1/2 inch water pipe.
I really want to tunnel it because I just know its going to sag and look rubbish after a couple of years if it's trenched.

Who does this sort of work? The bore hole would be about 7mtrs long and only needs to be 6 inches below surface I would have thought.

Can't help, but interested in the replies as I'd like to do similar eventually. I'd start by googling for a company that has a mole. Kicking myself I didn't run water to the front of the house when I had the floor up.

If it gravel should not be an issue, just move gravel around or add more?

Moleing will cost (sticks finger in the air) about £10 per metre, depending on what the soil is like.
We had a new house water supply put in which was about 50 metres in very rocky ground and, according to the guy who did it, was a right ba5tard!!
Our pipe was about 50cm underground and he put in a 40mm liner pipe in which he ran the new 25mm supply.
Very neatly done though.

Thanks for responses. So much easier when you know what to Google.

As mentioned under a gravel drive you won't notice it.

Well, a trench to lay electrical cables by a previous owner has sagged and there seems to be a tarmac like, solid surface under the gravel in places. I don't fancy trying to excavate.

Tunnelling it seems to be a more solid way IMHO.

Let us know how you get on.

Be sure you know where the service pipes and cables run!

Well that's a worry. I'll post when I get around to doing anything about it - I seem to be spending all my time cutting grass at the moment. Why can't it pick a length and stick to it!

Thought I'd finish this thread off - I like it when others do that;

I have just had the moling done and am really pleased about the results. In the end I had the drive moled in 2 places to allow me to get irrigation to all parts of the garden. So a total of 3 holes were dug out (by hand) and 2 pipes were put in, with my Gardena irrigation pipe fed through them. Apart from the new pipes sticking up, its as if nothing had happened, so well did they return the site to normal. That included lawn and graveled areas.

So I can heartily recommend Impact Moling of Basingstoke for a great job.
