Liquid damp proof membrane over uneven concrete

Hi guys, I would welcome some advice on what to get to smooth/cover dents in the substrate. We removed a layer of bitumen and concrete doesn't have a flat finish. Dents need to be covered sooner or later before laying ufh pipes and question is, shall we cover before or after the liquid dpm? I dont seem to find an all rounder solution which works, only levellers which won't cover full depth of dents as most need application to less than 12mm and other repair mortars won't stick to dmp or be too fragile to become structural underneath. Any ideas?
