Mole draining gone wrong

[Laggard]

Looks like lots of sink holes where the moles have collapsed?

When was it moled?
Is that caused by speed of water flow through the mole?
I‘ve had collapsed drains cause sink holes like that.

Any idea how deep mole is

 

[Laggard]

Mole drained 31/5/23 and then ploughed 1/7/23. Didn’t get it drilled with wheat due to weather (110mm rain from Storm Babet).

It’s either a drain washed out or a mole run.

Seen moles washed out causing collapse if moling is done on steeper land ie not moling at an angle to bank.

Hopefully its just the mole run.

Moled up and down the slope, should have gone at more of an angle then? We have had exceptional rainfall though.

I had a mole when i farmed in the UK. Clay land in leics and it worked well. I brought it here to France, along with all my kit, and tried it here. I get exactly that wherever I try it here. Actually I had some much larger holes than that

You need a few of these , then use the soil to fill your in

I would dig down to see if it is the mole as could be an old clay drain at the bottom . Just to be 100% sure. Interesting.

Direction to mole will be on your drainage plans.

24 inches is plenty deep enough for moleing in danger of disturbing drains

I have dug down to check moleing and porous back fill depth
mole at 20 inches as that was into all the back fill
my father usually put backfill to 10 inches as it usually settles down
on one field with clinker back fill it had settled to 20 inches

old drains can be as shallow as 10 inches in unsubsoiled land
