Morphology

waterproof = waterproof (transparent) = water + proof

The meaning is directly compositional: something that is waterproof is resistant to water.

Etymology

Waterproof can also mean the material itself, made of water + proof, so a waterproof fabric is cloth that will not let water through and so keeps things underneath dry.
