We have bought a house that is entirely made of precast concrete elements (reinforced concrete). Since there is no screed in the bathroom, we had to chip out 2cm (0.8 inches) of concrete in the shower area to create a slope for a level-access shower. Now the area looks like in the attached picture, and you can already see the steel reinforcement. Tiles will be installed there in a few weeks.
We have a very skilled tiler who will waterproof the area anyway, but we wanted to ask briefly how we can protect the concrete/steel from corrosion, since this 2cm (0.8 inches) layer of concrete is now completely missing. A friend of ours in the construction industry recommended “Sikaguard,” for example.
Do you have any other ideas or suggestions on what we can do to protect the concrete and steel over the long term?
Thank you in advance.

My intuition: there will be no walk-in shower there.
