ToughButterCup Posted April 12, 2020 Share Posted April 12, 2020 My recent re-aquaintace with the mark 1 shovel, MOT1, and Glacial Till has made me much more cautious about how deep to dig my foul drain trench. Its not a matter of popping down to fetch red diesel any more ..... I have found these two YT videos very helpful Osma's guidance (at 4:05) and this gentle bit of mickey taking ... How much shingle needs to be put under the drainage pipe? The guy from Osma says 100mm; is he right? I can't find any guidance that says it must be 100mm.

Russell griffiths Posted April 12, 2020 Share Posted April 12, 2020 I’m putting normal diesel in the digger, breaking my heart and bank account £60 this week already 100mm by the way. Link to comment Share on other sites More sharing options...

What size you using? I got a solid 3 days graft out of a little e10 for less than 20 quid in white Link to comment Share on other sites More sharing options...

But the red here was close to £1/litre unless you could find space for a 500 litre tank before the virus kicked off, so not much difference. I am doing 100mm for the drains as in diagram 10 part b in Approved Document H Link to comment Share on other sites More sharing options...

Temp Posted April 12, 2020 Share Posted April 12, 2020 The gravel also makes it easier to level the bottom of the trench. I think it would be hard to keep the bottom of the trench flat enough to allow much less than 100mm. Link to comment Share on other sites More sharing options...
Miek Posted April 13, 2020 Share Posted April 13, 2020 Worth considering the pipe bedding material. Where I live pea shingle (6mm) is £25/t but graded limestone 'pipe bedding' which is basically 6-10mm clean is only 18/t. Better check with your building inspector but mine was happy with either. I'm laying around 100m of it so it does make a difference. 2 Link to comment Share on other sites More sharing options...
