Bay Of Biscay Soil
Bay of Biscay is a term used in South Australia for a dark clay soil of a highly reactive nature, forming a sticky mass when wet and shrinking during long dry spells, developing deep cracks. Though found elsewhere, it is prevalent in many parts of the Adelaide plain. It is a particular challenge to all-masonry structures, resulting in fractured foundations and vertical cracks in walls. It is not uncommon to see older buildings with walls braced with railway iron or having long steel rods at ceiling level, holding opposite walls together. A common type of construction in such areas is brick-veneer — essentially a timber-framed building with non-structural brick outer walls — accepting cracks as a likely, but cosmetic outcome, not affecting the building's performance.

Gilgai is also used to refer to the overall micro-relief in such areas, consisting of mounds and depr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Australia
South Australia (commonly abbreviated as SA) is a States and territories of Australia, state in the southern central part of Australia. With a total land area of , it is the fourth-largest of Australia's states and territories by area, which includes some of the most arid parts of the continent, and with 1.8 million people. It is the fifth-largest of the states and territories by population. This population is the second-most highly centralised in the nation after Western Australia, with more than 77% of South Australians living in the capital Adelaide or its environs. Other population centres in the state are relatively small; Mount Gambier, the second-largest centre, has a population of 26,878. South Australia shares borders with all the other mainland states. It is bordered to the west by Western Australia, to the north by the Northern Territory, to the north-east by Queensland, to the east by New South Wales, to the south-east by Victoria (state), Victoria, and to the s ...

Building (Australian Magazine)
''Building'', full title ''Building: The Magazine for the Architect, Builder, Property Owner and Merchant'', was a monthly magazine about architecture and building published by the Building Publishing Company in Sydney, New South Wales, Australia, from 1907 to 1942. It was subsequently published under the following titles: ''Building and Engineering,'' ''Building, Lighting and Engineering,'' ''Building,'' ''Products, Projects and Trends in Building,'' ''Building: Australia's National Building Journal.'' Publication history ''Building: The Magazine for the Architect, Builder, Property Owner and Merchant'' was first published in September 1907 by the Building Publishing Company, established by George Augustine Taylor and his wife Florence Mary Taylor. The magazine "offered influential commentary on the built environment in Australia for the next half century". Florence Taylor wrote a regular column in the magazine which highlighted women in architecture. From 1927 to October 193 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brick-veneer
Masonry veneer walls consist of a single non-structural external layer of masonry, typically made of brick, stone or manufactured stone. Masonry veneer can have an air space behind it and is technically called "anchored veneer". A masonry veneer attached directly to the backing is called "adhered veneer". The innermost element is structural, and may consist of masonry, concrete, timber or metal frame. Because brick itself is not waterproof, the airspace also functions as a drainage plane, allowing any water that has penetrated the veneer to drain to the bottom of the air space, where it encounters flashing (weatherproofing) and is directed to the outside through weep holes, rather than entering the building. Other advantages of a masonry veneer include: * The air space can include additional insulation, which is typically in the form of rigid foam, increasing the thermal performance of the wall. * The structural framing or masonry backup can be erected first to allow the re ...

Hills Gazette
A hill is a landform that extends above the surrounding terrain. It often has a distinct summit, and is usually applied to peaks which are above elevation compared to the relative landmass, though not as prominent as mountains. Hills fall under the category of slope landforms. Terminology The distinction between a hill and a mountain is unclear and largely subjective, but a hill is universally considered to be not as tall, or as steep as a mountain. Geographers historically regarded mountains as hills greater than above sea level. In contrast, hillwalkers have tended to regard mountains as peaks above sea level. The ''Oxford English Dictionary'' also suggests a limit of and Whittow states "Some authorities regard eminences above as mountains, those below being referred to as hills." Today, a mountain is usually defined in the UK and Ireland as any summit at least high, while the UK government's Countryside and Rights of Way Act 2000 defined mountainous areas (for the ...

Gilgai
A gilgai is a small, ephemeral lake formed from a surface depression in expanding clay soils. Gilgai is also used to refer to the overall micro-relief in such areas, consisting of mounds and depressions. The name comes from an Australian Aboriginal word meaning small water hole. The pools are commonly a few metres across and less than deep but, in some instances, they may be several metres deep and up to across. Gilgais are found worldwide wherever there are cracking clay soils and marked wet and dry seasons. Gilgais are also called melonholes, crabholes, hogwallows, or puff and shelf formations. Formation Gilgais are thought to form in vertisols through repeated cycles of swelling when wet and subsequent shrinkage upon drying. That action, known as argillipedoturbation, causes the soil to crack when dry, allowing loose soil material to fill the cracks. When the soil swells upon subsequent re-wetting, the soil pressure cannot be dispersed into the now-full cracks and the so ...
