Any builders? DPM externally exposed

[Deleted member 262063]

I have a single skin brick shed with render outside, there is a wedge of concrete around most of the bottom. I am removing it to slab up to the shed.
Upon removing it I've noticed the blue DPM is showing (it was always exposed in other areas.

Should I be looking at tacking it to the concrete slab or is this standard building see pictures

The problem is the dpm has been bridged by the outside ground level via the existing concrete. There may be a dpc higher up the wall but that is unlikely given the position of the bottom of the door. If its not living accommodation and there is no current damp, dropping the finished height of the path might be the practical solution.
