Crazy building line

I have the ground unit. The two units above me have a balcony which is set back more than a metre from mine. This means that all of the water, both rain and tap, comes directly onto my balcony. Unfortunately my balcony does not have a sufficient g radiant to allow the water to run of so it pools and is creating mould. These are separate issues both of which I have reported to Strata Management who say neither is a strata problem. I feel that this is a building fault, a mad one at that, as the consequences were obvious to see. Any suggestions, ideas, facts?
