Trimming up Concrete Slab DPM Post your questions and get answers regarding all areas of drives, pathways and patios

[Bogart]

I have just had a concrete slab laid with a DPM. I would like opinions as to where to trim the DPM at the sides. Hopefully the attached drawing makes it easier to understand.
I obviously do not want the DPM to extend past point A or it will be visible. I am uncertain where to cut it between points A and B
