Balcony Concrete Cancer on the Sunshine Coast

What balcony concrete cancer on the Sunshine Coast actually involves

Cracks or pores in concrete let water seep in, and that water reacts with the steel reinforcing to produce rust. The corrosion product takes up more space than the metal it formed from, and the part of the concrete that carries the load is the part being eaten away, which is why the damage is serious. A balcony takes the weather on several faces, so the edge and the underside are where the damage is looked for.
