Yes, it is cement render.



Modern cement render 'should' be OK providing it is checked on a regular
basis for maintainance purposes.. A lot of the myth of ivy being
'damageing' comes from instances where its supporting striucture (be it
wall, house, tree etc) has already been allowed to come into a state of
disrepair through neglect.. Either through complete neglect or because
people do not bother to check up close whilst the structure is covered
by the vine..
