I want to mount bookshelves on an internal wall in a mid-90s build apartment. I plan to use the metal vertical rails with brackets and fill them with books - so it will be heavy.
Here's the problem - I can't determine what kind of wall material it is. If I knock on it, it sounds hollow, or at least more hollow than the external walls. But if I drill into it, it seems to be solid all the way through to the next room - about 6 inches. I have tried this in three separate locations, 6 inches apart vertically and horizontally, to check if I was drilling into wooden battens.
Does anyone have any clue as to what kind of wall this is? And if it would support heavy bookshelves?
Many thanks for any advice.
