is reinforced concrete enough to carry out a vmc?

Hello

I created an insulation inside the reinforced concrete roof and wonder if there will be condensation on the concrete if a few towers allow air to pass.
this concrete is quite rough
I do not know if I would have a formation of chamoignons and if I then have to use a vmc hygroragable
the installation of vapor barrier will not be unreliable and the place very quirky to avoid any risk of air leakage
the configuration of the premises is very complex and I think about an internal air circulation with air chambers very dry l
because at the base the insulators are planned to be ventilated in summer to evacuate the heat of the concrete which heats in the sun by the air inlet coming from the outside

Thank you

Re: is reinforced concrete breathable enough to do without a cvm?

Bonsoir
reinforced concrete is watertight, not "breathable" so provide a blade of ventilation air

Thank you
air knife yes, I made one but I will have to ventilate internally with dry air
I imagine several possibilities
