Hello everyone, I have built a limestone wall between two terraces. What is the best way to fill gaps that have formed between the stones? Because of the tongue and groove system, you can’t get in between, but soundproofing isn’t really possible this way, is it? The manufacturer states that adhesion is only applied at the top and bottom.

I would use masonry mortar or lime-cement plaster.
Will the wall stay as it is, or are we planning to do something else here?

First, the wall will be plastered, but the vertical joints at the bottom sometimes go all the way through. Later, this will serve as a wall for an extension and needs to be soundproof and insulated.This is the separation between two terraces. It is enough to plaster properly—making sure to press the plaster firmly into the joints.What I don’t understand is your second sentence. A wall for an extension? Soundproof and insulated? How should I imagine this extension, because if so, you will need to comply with energy efficiency regulations, and I wonder how you plan to install the insulation on the other side of the terrace (i.e. on terrace 2). You will likely need 16–20cm (6–8 inches) of insulation as a minimum. Or do you own both sides?
Basically, what I said applies in this case as well.
