Good evening. Its been a while since I posted anything on the forum...but I know certainly I would be assisted with the kind of question I have. I happen to trust info I received here big time.
Beside having done my research fully, I'd like to know if anyone has used these kind of concrete boxes, do we even have them in SA? (Picture attached)

I understand I cannot put a surfix cable under concrete and so how would I go about doing (constructing) a light outlet on reinforced concrete pillar without this box that you can put nails on to wooden plate?
Is there any product or anything I could use or do to make it easier? I'd appreciate your advice in this regard
