What render finish is this.

This external wall has had a render pebbledash/stucco? finish added at some stage, although looks within the last few years. As you can see from the pics, part of it has disintergrated.

For some strange reason the wall inside is damp up to a clean 2m high line. Above this, the condition of the plaster significantly improves and my moisture meter picks up no damp. Obviously there is issues below this level. The other walls are stud.

Outside, the stucco finish is solid in the mirrored affected area except for the bit thats fallen off, however my moisture meter tell me its has moisture content for surprisingly the same 2m height. Above that its perfectly dry.

Whats going on?

Am i right in calling this stucco. Is it likely to be a rising damp uissue or did the previous guys fail to put some waterproofer into the render.

Thanks in advance

looks a bit like rising damp, but it might be the render finish has bridged the DPC perhaps.
