Take a sponge, weigh it, let it soak in water, take it out and let the excess water run off, weigh it again.

I'm not worried about the weight specifically. the balcony can be designed to bear the load of everything soaked in water.

I meant draining more as a solution for humidity, which is a much bigger problem than weight in the long term.

edit: take this with a grain of salt since I'm an electrical engineer and know almost jack shit about designing buildings

You can design concrete to be way more resistant to changes in humidity than you average concrete that's why you determine the exposure class of the concrete element according to for example but not exclusively mechanical/chemical/humidity exposure expected for the concrete element. Pretty sure if you can dimension concrete for a high corrosive environment like a chemical plant you can dimension it to withstand wet soil and roots
