I have a corridor with a sand/cement screed that is completely f***d
up. It was laid without enough cement or water and is now breaking up.

The carpet was (glued?) directly to the screed.

To minimise disruption I would like to: -

Lift carpet
Make good obvious holes
Cover with floor leveling compound
Put down exterior ply layer
Relay carpet

Any thoughts on this process?

I am wary about lifting all screed, because of disruption and likely
hood of damaging dpm and or polystyrene insulating slabs.

Cheaper method would be.

Lift carpet
Put down exterior ply layer
Relay carpet

Plywood will be enough to level and cover the floor on its own I think.

Ah. One thing to say here, if you don't want to lift out the crumbling
mess that was the screed and replace, which is the best option.

Get a ****load of PVA and dilute it 50:50 - really quite strong and
pioyer it over all the crumbling mess.

Its expensive, but it WILL stablise the mess. I have actually glued a
cracked slab of screed in place with it.

Once the crumbly mess is sorted, fix biggest cracks with mortar, then go
for levelling compond. Be aware that levelling compund doesn't level
though :-)

However it may be cheaper to lift the lot and get it rescscreeded
professionally.

By putting down exterior ply on the top you will hear/feel crunching every
time you walk on it as I do at a friend's house.

not if you glue it down. And that same glue can bind the junk together.
PVA or other glue diluted can do a remarkable job of sticking
disintegrating things back together.
