This was done to provide guns for arming merchant ships and auxiliaries and to improve watertightness under North Atlantic conditions.

The government of New Zealand has set up a mediation serviceWeathertight Homes Resolution Service to resolve cases of houses that failed watertightness.

High end fuel bladders are made of elastomer coated fabrics manufactured by homogeneous vulcanization in one operation. The fabrics ensure mechanical resistance. The coating and design engineering provide watertightness.

The building envelope should be examined thoroughly for cracks, watertightness (infiltration or leaks) and mortar joints. It is important to examine these exterior walls for future fenestration and air conditioning ducts.

There were seven Gemini boilerplates: BP-1, 2, 3, 3A, 4, 5, and 201.Field Guide to American Spacecraft Boilerplate 3A had functional doors and had multi-uses for testing watertightness, flotation collars, and egress procedures.

The Barton Aqueduct of 1761, and subsequent canal aqueducts in the United Kingdom, used large quantities of masonry and puddling to obtain watertightness. After the success of The Iron Bridge in 1789, however, cast iron was used by Telford on aqueducts such as Chirk and Pontcysyllte. Aqueducts built in the early part of the 19th century use either puddle clay or an iron trough in no particular pattern. The Almond Aqueduct uses an iron trough to achieve watertightness, as well as containing the outward pressure of the water, allowing it to be of more slender construction than a purely stone aqueduct such as the Kelvin Aqueduct.

Each block was carefully dressed to accurate dimensions and laid in courses 0.6m high. The dam wall extended about 4m into the abutments on each bank. At Moriarty's suggestion the stones were bonded together with cement mortar to ensure watertightness. Two different cements were imported from England.

89, No. 1, Centennial Issue (Jan., 1985), pp. 71-101. The ship was intended for long service and underwent four major repairs in her life. In the last repair her owner(s) had a skin of lead sheathing of 1,5 to 2 millimeters thickness applied to her body to hopefully keep the old ship comparatively safe from woodworm and probably help watertightness.

The concrete shell of the roof is left rough, just as it comes from the formwork. Watertightness is effected by a built-up roofing with an exterior cladding of aluminium. The interior walls are white; the ceiling grey; the bench of African wood created by Savina; the communion bench is of cast iron made by the foundries of the Lure.

We spent the next two hours feeding ammunition to the gunners. Ifkin is now recognized as the first U.S.sailor to report the Japanese attack that completely shocked the American Navy and burst the nation into the World War.{cite: Kruth interview} By 0800, the attack on Pearl Harbor was well underway. The men of San Francisco secured the ship for watertightness and began looking for opportunities to fight back.

A joint in the iron trough that makes the canal watertight The Barton Aqueduct of 1761, and subsequent canal aqueducts in the United Kingdom, used large quantities of masonry and puddling to obtain watertightness. After the success of The Iron Bridge in 1789, however, cast iron was used by Telford on aqueducts such as Chirk and Pontcysyllte. Aqueducts built in the early part of the 19th century use either puddle clay or an iron trough in no particular pattern. The Slateford Aqueduct has eight arches of span, and is long and high above the Water of Leith.

Having demonstrated the watertightness and corrosion resistance of duralumin monocoque flying boat hulls with the Short Cockle, Shorts became leaders in the design of metal floats for seaplanes. The floats for both the Supermarine S.4 and Gloster III Schneider Cup seaplanes were built by Shorts. They had built their own hydrodynamic testing canal at their Rochester base to explore the performance of floats on the water and decided to build a small aircraft to test them in flight. This was the Short S.7 Mussel; the name was a natural complement to the Cockle but also a nod to "Mussel Manor", the clubhouse on Shorts' first airfield at Sheppey.

The unique characteristic of the Spragg Bag system is not the large volume of water in each bag, but what is called the world's strongest zipper (produced by Italian company Ziplast) that allows connection of several bags together in long trains.WATERBAG TECHNOLOGY AND INTER-STATE WATER TRANSFERS The large connecting zipper can be operated manually or by remote control with radio signals. The string of such flexible fabric "waterbags" may be coupled to a barge via a reinforced fabric nose cone where a tow line is attached. The REFRESH scheme is enabled by a specialty zipper, again developed by Ziplast, that uses a completely different tooth engagement design able to keep the strength of the original "Spragg" zipper while adding watertightness.
