Renovating shower room, and there are both interior walls (non-load-bearing) made of Siporex/lightweight concrete and so-called outer wall insulation of the same material. During floor chiseling and drilling for new pipes, the lightweight concrete has been severely damaged. I assume there's not much else to do but tear down and rebuild?
Interested in opinions?
What is the recommended material? I understand that something like ytong or similar, maybe this Micropor, might be suitable? Which is glued as I understand? No reinforcement required?
In some elements, grooves have been cut by the plumbing company, can these be filled with some common type of concrete/putty?
Everything is a wet area in the basement, grateful for opinions.
