Got a foul drain under my gravel driveway. 4" pvc. Encased in concrete about 4" above and below. Proper stone makeup above 30-70mm clean, type1 then driveway gravel all compacted.
Top of pipe is about 500/600 below ground. I've been paranoid about anything over 7.5t driving over it but need to get some skips in. Everyone keeps telling me fully loaded 18t skip lorry be okay as weight will spread. They've all been in the game longer than me and seem pretty sure, however they don't have to dig it up and change it if things go wrong.
What do you lot think? I've seen some shallow drains in footpaths, albeit clay.
