Uneven concrete floor with low DPC

This is my very first post, so hope I get it right.

I have a question regarding the part levelling of a garage floor. It’s a twin garage which has a very uneven floor and about a quarter of it (6ft x 5ft )needs to be raised. The amount it needs to be raised varies from 90mm to about 5 where it joins the old concrete. As you can see from the picture, the DPC is almost at ground level which means I can’t easily raise the floor level without it going above it. I was thinking about using some DPM where the new concrete meets the wall above the old DPC. Would this work?

Many thanks,
