watertightness
Seals out all moisture
Watertightness is the quality of being impervious to water—the degree to which something prevents water from passing through.
Engineers test the watertightness of hulls, seals, and basement foundations.
Figuratively, a legal argument's watertightness is how well it holds up against challenges: The watertightness of his alibi convinced the jury.
