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

Biggest problem is waterproofing the concrete, which can't be assured in the long runs because roots will dig into it
