Aco drain solution - without lifting the drain / driveway?

[MattM1]

I have an ACO drain on new build (7 year old), the drive keeps sinking in one corner, most recently repaired by setting the outage edge in a motar bed. Aco drain is solid, looks to have been laid on concrete and haunched. Looking for a reasonably permanent fix without needing to lift the drive / ACO. I was thinking of buying a 110mm insert for the pipe to bridge the gap, tidying up the opening so it fits around the insert and using a flexible waterproof filler around that. Any better ideas / products? (DIYable, success measured by not having to fix the drive every 3 months….

What is the actual issue? Is the drain pipe not colleting water from the Aco outlet as efficiently as you would like and weeping into the ground?

Weeping into the ground and washing the sand away under the paving

If the weeping occurs where the surface water drains into the gulley could you not take some blocks out and concrete round the new fitting.

It's a cowboy botch job. Re-do it properly using one of these...

If you put a giant lump of filler in, it will definitely end up detaching and falling into the pipe, causing much bigger issues.

It's a difficult fix without lifting and re-bedding the Aco channel.

We'd prepare the drain pipe, concrete flush with the top of the drain pipe, then bed the Aco on top of the (wet) concrete, using a screed sand mortar bed. We'd then remove the excess mortar from around the joint and give the pipe a careful blasting with the hose.

Too late for that now though.
