Because plastic decking is lighter per cubic inch than wood, it will float easily. There are no micro-spaces for the water to seep into, which means that the material will float indefinitely. If the decking is all-plastic, then its resistance to rot and mildew allows for its use in docks and other areas where there is constant water contact.
