Horizontal barrier injection method

Hello

I have read that there are different methods for horizontal barriers. Often the injection method is favored. Can someone tell me if this method is also suitable for a 20cm thick concrete wall?

One more question: Due to capillarity, water can rise up a wall. Is this also possible with a concrete wall, or is this only the case with masonry?

Thank you very much

These injection methods can also work with concrete - except with [wasserundurchlässigem Beton].

But: Horizontal barriers make no sense in a leaking basement. A basement exterior wall has contact with moisture over its entire height!
