Watertight. Must exclude at least 65 GPM of water from a 1-inch nozzle delivered from a distance not less than 10 feet for 5 min. Used outdoors on ship docks, in dairies, in wastewater treatment plants and breweries. X (as 4X) indicates additional corrosion resistance. 5: Dust-tight.
Waterproofing conducted on the exterior of a freeway tunnel. Waterproofing is the process of making an object, person or structure waterproof or water-resistant so that it remains relatively unaffected by water or resisting the ingress of water under specified conditions.
A hull is the watertight body of a ship, boat, submarine, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline.
Watertight subdivision limits loss of buoyancy and freeboard in the event of damage, and may protect vital machinery from flooding. Most ships have some pumping capacity to remove accumulated water from the bilges, but a steel ship with no watertight subdivision will sink if water accumulates faster than pumps can remove it.
Schematic cross section of a pressurized caisson. In geotechnical engineering, a caisson (/ ˈ k eɪ s ən,-s ɒ n /; borrowed from French caisson 'box', from Italian cassone 'large box', an augmentative of cassa) is a watertight retaining structure [1] used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, [2] or for the repair of ships.
The sunken vessel, lying on the seabed at a depth of some 50 meters (164 feet), is thought to have watertight safes containing two super-encrypted hard drives that hold highly classified ...

Puddling is both the material and the process of lining a water body such as a channel or pond with puddle clay (puddle, puddling) – a watertight (low hydraulic conductivity) material based on clay and water mixed to be workable.
