impermeable
Nothing gets through
Impermeable means not allowing passage through, especially of liquids or gases.
An impermeable membrane blocks water; impermeable rock traps oil beneath it.
The word appears in scientific and technical contexts: The clay layer was impermeable to groundwater.
Figuratively, someone impermeable to criticism remains unaffected by it.
