impermeable + noun

impermeable to + noun

用法筆記

More formal and technical than 'waterproof'. While 'waterproof' applies only to water, 'impermeable' can describe resistance to any liquid or gas. The subject is usually a material, layer, or barrier — not an object's function. Frequently used in construction, geology, and manufacturing contexts.

常見錯誤

'impermeable' describes the material, not the container itself.

in everyday English, 'waterproof' is more natural for finished products; 'impermeable' describes the material or layer.
