Moling soil pipe?

[Robbiec99]

Hi all, not a diy /build expert at all however I have a question regarding putting a toilet in my detached garage… I need to run a soil pipe down my driveway (20/25 foot)

The drive will need to come up but I just wondered could one of these moling machines be used to run the pipe or is it not do able?

Thanks

Not really as it’s a certain amount of fall and bedded on pea gravel

Moling/directional drilling is only really suitable for pressure pipework, and/or welded HDPE pipework, and you'd need to look at directional drilling to achieve the required fall on the run. Likely to be prohibitively expensive, for the short distance required.

Open cut, and conventional drainage pipework, (plastic or clay), laid to suitable fall on proprietary bedding material will be the cheapest option.
