Could you help this inspector in South Africa if you know the answer? Here’s the message he sent me this morning:
I have a question not relating to Spectacular, I hope you can assist me. In South Africa 99.99% of houses are brick and mortar, occasionally we have interior walls made from dry walling but this is literally 0.01% of the time. I recently inspected a house in an area I am very familiar with and found the walls to be constructed in a way I am not familiar with, and would like to know from you, or if you know someone who could tell me more about it just from the photos attached.
In my experience, guniting of swimming pool walls is the closest thing I have seen to this construction. In the pics you will see what seems to be some type of expansion foam centre, reinforced on each side with cement overlaid both sides.
Would you be able to tell me what this is or point me in the right direction?
