deck post hole too close to drain

[buddy]

I have drilled a stump hole for a deck that is 450mm deep. Unfortuantly the hole had wandered whilst drilling and has clipped a trench for a aggi drain. The hole fills with water from the drain. I will realign the hole by hand but could someone please advise what would be the right way of of closing or backfilling up the aggi drain breach?

once you fill the footing with concrete the drain wont have anywhere to leak to. Should be fine IMO

Agree but I would keep digging to 600 min to get well past the loose crap from the drain trench. You could even stick a bit of formwork in (piece of timber or fibro) to keep the concrete out of the trench and backfill when its set
