Earthbag Construction
Earthbag construction is an inexpensive building method using mostly local soil to create structures which are both strong and can be quickly built. Earthbag development Features It is a natural building technique developed from historic military bunker construction techniques and temporary flood-control Dike (construction), dike building methods. The technique requires very basic construction materials: sturdy sacks filled with organic material usually available on site. Standard earthbag fill material has internal stability. Either moist subsoil that contains enough clay to become cohesive when tamped, or a water-resistant angular gravel or crushed volcanic rock is used. Walls are gradually built up by laying the bags in courses—forming a staggered pattern similar to bricklaying. The walls can be curved or straight, domed with earth or topped with conventional roofs. Curved walls provide good lateral stability, forming round rooms and/or domed ceilings like an igloo. Build ...

Emergency Shelter
An emergency shelter is a place for people to live temporarily when they cannot live in their previous residence, similar to homeless shelters. The main difference is that an emergency shelter typically specializes in people fleeing a specific type of situation, such as natural or man-made disasters, domestic violence, or victims of sexual abuse. A more minor difference is that people staying in emergency shelters are more likely to stay all day, except for work, school, or errands, while homeless shelters usually expect people to stay elsewhere during the day, returning only to sleep or eat. Emergency shelters sometimes facilitate support groups, and/or provide meals. Post-disaster emergency shelter is often provided by organizations or governmental emergency management departments, in response to natural disasters, such as a flood or earthquake. They tend to use tents or other temporary structures, or buildings normally used for another purpose, such as a church or school. ...

Subsoil
Subsoil is the layer of soil under the topsoil on the surface of the ground. Like topsoil, it is composed of a variable mixture of small particles such as sand, silt and clay, but with a much lower percentage of organic matter and humus. The subsoil is labeled the soil horizon, B Horizon in most soil mapping systems. Because it has less organic matter than topsoil, subsoil soil color, soil colour is mainly derived from iron oxides. Iron oxides and clay minerals form due to soil formation, weathering. Rainfall moves these weathering products downward as solutes and colloids by rainfall. The subsoil is the depth where these weathering products accumulate. The accumulation of clay minerals, iron, aluminum, and organic compounds is called illuviation. Whereas the topsoil tends to be the depth of greatest physical, chemical, and biological activity, the subsoil is the depth of most deposition. Due to physical, chemical, and biological activity, the subsoil generally has a soil struct ...

Trench
A trench is a type of digging, excavation or depression in the ground that is generally deeper than it is wide (as opposed to a swale (landform), swale or a bar ditch), and narrow compared with its length (as opposed to a simple hole or trapping pit, pit). In geology, trenches result from erosion by rivers or by geological movement of tectonic plates. In civil engineering, trenches are often created to install underground utilities such as Pipeline transport, gas, Water distribution system, water, Underground power lines, power and Undergrounding, communication lines. In construction, trenches are dug for foundations of buildings, retaining walls and dams, and for Tunnel construction#Cut-and-cover, cut-and-cover construction of tunnels. In archaeology, the "trench method" is used for searching and Excavation (archaeology), excavating ancient ruins or to dig into stratum, strata of sedimented material. In geotechnical engineering, trench investigations locate faults and investigat ...

April 2015 Nepal Earthquake
The April 2015 Nepal earthquake (also known as the Gorkha earthquake) killed 8,962 people and injured 21,952 across the countries of Nepal, India, China and Bangladesh. It occurred at on Saturday 25 April 2015, with a magnitude of Moment magnitude scale, Mw 7.8–7.9 or Surface wave magnitude, Ms 8.1 and a maximum Mercalli intensity scale, Mercalli Intensity of X (''Extreme''). Its epicenter was east of Gorkha District at Barpak, Gorkha, roughly northwest of central Kathmandu, and its hypocenter was at a depth of approximately . It was the worst natural disaster to strike Nepal since the 1934 Nepal–India earthquake. The ground motion recorded in Kathmandu, the capital of Nepal, was of low frequency, which, along with its occurrence at an hour when many people in rural areas were working outdoors, decreased the loss of human lives. The earthquake triggered 2015 Mount Everest avalanches, an avalanche on Mount Everest, killing 22 people, the deadliest incident on the mountain o ...

Super Adobe
Superadobe is a form of earthbag construction that was developed by Iranian architect Nader Khalili. The technique uses layered long fabric tubes or bags filled with adobe to form a compression structure. The resulting beehive-shaped structures employ corbelled arches, corbelled domes, and vaults to create sturdy single and double-curved shells. It has received growing interest for the past two decades in the natural building and sustainability movements. History Nader Khalili popularized earthbag construction. Initially in 1984 in response to a NASA call for housing designs for future human settlements on the Moon and on Mars, he proposed using Moon dust to fill the plastic Superadobe tubes and velcroing together the layers (instead of using barbed wire). He came to term his particular technique of earthbag construction "Superadobe". Some projects have been done using bags as low-tech foundations for straw-bale construction. They can be covered in a waterproof membrane to k ...

Nader Khalili
Nader Khalili (; 1936–2008) was an Iranian Americans, Iranian-born American architect, author, and educator. He is best known for his inventive structures that incorporated a range of atypical building materials to provide shelter in the developing world and emergency contexts. His work was heavily influenced by the traditional arid house designs of Iran. Early life and education Nader Khalili was born in Tehran, Pahlavi Iran into a large family, he had 8 siblings. He attended the University of Tehran where he studied Persian literature and poetry; followed by the study of engineering and architecture at Istanbul Technical University. Career In 1970, he was licensed by the state of California and practiced architecture in the U.S. and around the world. In 1975, Khalili was working in Iran at a conventional western-style architecture firm on projects for the Shah Mohammad Reza Pahlavi, when he realized his profits were coming at the expense of traditional Iranian architecture ...

Earthship
An Earthship is a style of architecture developed in the late 20th century to early 21st century by architect Mike Reynolds (architect), Michael Reynolds. Earthships are designed to behave as Passive solar building design, passive solar earth shelters made of both natural and Upcycling, upcycled materials such as earth-packed Steel-belted radial, tires. Earthships may feature a variety of amenities and aesthetics, and are designed to withstand the extreme temperatures of a desert, managing to stay close to 70 °F (21 °C) regardless of outside weather conditions. Earthship communities were originally built in the desert of northern New Mexico, near the Rio Grande, and the style has spread to small pockets of communities around the globe, in some cases in spite of legal opposition to its construction and adoption. Reynolds developed the Earthship design after moving to New Mexico and completing his degree in architecture, intending them to be "off-the-grid-ready" houses ...

Root Cellar
A root cellar (American and Canadian English), fruit cellar (Mid-Western American English) or earth cellar (British English) is a structure, usually underground. or partially underground, used for food storage, storage of vegetables, fruits, nut (fruit), nuts, or other foods. Its name reflects the traditional focus on root vegetable, root crops stored in an underground basement, cellar, which is still often true; but the scope is wider, as a wide variety of foods can be stored for weeks to months, depending on the crop and conditions, and the structure may not always be underground. Root cellaring has been vitally important in various eras and places for winter food supply. Although present-day food distribution systems and refrigeration have rendered root cellars unnecessary for many people, they remain important for those who value self-sufficiency, whether by economic necessity or by choice and for personal satisfaction. Thus, they are popular among diverse audiences, includi ...

Spring Box
A spring box is a structure engineered to allow groundwater to be obtained from a natural spring. The spring box functions to protect the spring water from contamination, normally by surface runoff or contact with human and animals, and provides a point of collection and a place for sedimentation Sedimentation is the deposition of sediments. It takes place when particles in suspension settle out of the fluid in which they are entrained and come to rest against a barrier. This is due to their motion through the fluid in response to th .... In many instances it also acts as the principal water storage for the household water supply. The area surrounding the spring box should be fenced off in order to reduce the risk of contamination from animal feces. An overflow pipe should be installed into the spring box, as well as a sedimentation drain and the supply lines to & from it, and it should also have a well fitting lid. If the flow rate is relatively high, a spring box may not ...

Cistern
A cistern (; , ; ) is a waterproof receptacle for holding liquids, usually water. Cisterns are often built to catch and store rainwater. To prevent leakage, the interior of the cistern is often lined with hydraulic plaster. Cisterns are distinguished from wells by their waterproof linings. Modern cisterns range in capacity from a few liters to thousands of cubic meters, effectively forming covered reservoirs. Origins Early domestic and agricultural use Waterproof lime plaster cisterns in the floors of houses are features of Neolithic village sites of the Levant at, for instance, Ramad and Lebwe, and by the late fourth millennium BC, as at Jawa in northeastern Lebanon, cisterns are essential elements of emerging water management techniques in dry-land farming communities. Early examples of ancient cisterns, found in Israel, include a significant discovery at Tel Hazor, where a large cistern was carved into bedrock beneath a palace dating to the Late Bronze Age.
