Central heating leak under the concrete floor..

Hi, I have a lot of dampness coming up the wall in my hallway. The red pressure tank in the picture drops from 1.5 bar to zero practically in 24hrs without any zones being turned on Is it possible to blank off zones one at a time to isolate the leak down to a certain pipe?

Each zone (and radiator) can be isolated at the manifold and then pressure tested, but the dampness probably identifies the leaking zone.
You might need a plumber to do this.
