EVA foam rolls that are waterproof are structured to resist water and moisture. Because EVA foam is closed – cell, it provides a good barrier to water, making these rolls useful in submerged or damp environments. In the marine industry, they are used for flotation devices, boat hull lining, and decking. Waterproof EVA foam rolls can also be used in construction as a basement or roof waterproofing insulation. They are used to guard outdoor equipment and gear against splashes and rain. Even in wet conditions, these rolls sustain good functionality and durability due to their shock absorption and cushioning capabilities.
