impermeability
Nothing gets through
Impermeability is the quality of not allowing passage through—especially of liquids or gases.
A material with high impermeability blocks water or air: The impermeability of the clay layer prevented groundwater contamination.
The term extends to figurative barriers: His impermeability to criticism frustrated his colleagues.
