Earthbag construction Wikipedia. Earthbag School Building Survived Nepals 2. Quake, Edge of Seven. Earthbag construction is an inexpensive method using mostly local soil to create structures which are both strong and can be quickly built. It is a natural building technique developed from historic military bunker construction techniques and temporary flood control dike building methods. The technique requires very basic construction materials sturdy sacks filled with organic material usually available on site. PNG' alt='S_Code Adobe' title='S_Code Adobe' />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. Buildings with straight walls longer than 5 m 1. International standards exist for bracing wall size and spacing for earthen construction in different types of seismic risk areas, most notably the performance based standards of New Zealand1 recommended by the ASTM Internationals earth building standards2. Static shear testing shows that earthbag can reach similar strengths to New Zealands reinforced adobe standards with specific soil strengths and reinforcement3 although unreinforced weak soil earthbag can have lower shear strength than unreinforced adobe. To improve friction between bags and wall tensile strength barbed wire is usually placed between courses. Twine is also sometimes wrapped around the bags to tie one course to the next, to hold in progress structures together and keep courses well seated on barbed wire prongs.

Collaborative post by Mateusz j00ru Jurczyk and Gynvael Coldwind Several months ago, we started an internal Google Security Team effort to improve the general. Rebar can be hammered into walls to strengthen corners and opening edges and provide resistance against overturning. The structure is typically finished with plaster, either cement stucco on a strong mesh layer or an adobe or lime plaster, to shed water and prevent fabric UV damage. This construction technique is one of the most versatile natural building methods and can be used for benches, freestanding walls, emergency shelters, temporary or permanent housing, or barns and commercial buildings. Earthbag is frequently chosen for many small to medium sized institutional structures in the developing world. Subgrade structures including underground and bermed dwellings such as Earthships, cisterns, spring boxes, root cellars, and retaining walls can be built with stabilized soil fill or with additional reinforcement and water resistant gravel or sand fill. Earthbag developmenteditSuperadobeeditWhile Gernot Minke, the German professor of earthen architecture, first developed a technique of using bags filled with pumice to build walls, it was architect and builder Nader Khalili who first popularized earthbag construction particularly for residential buildings4.

The Immigration and Nationality Act, or INA, was created in 1952. Before the INA, a variety of statutes governed immigration law but were not organized in one. Khalili called his technique superadobe, because he filled the bags with moistened adobe soil. Buildings at the Cal Earth Institute in Hesperia, CA, which he established in 1. Khalili pioneered code approval of earthbag domes for seismic risk regions5. Several books and videos have been produced by the institute to demonstrate his methods, however a number of other individuals and groups now offer training workshops. WriterseditAlthough Joseph Kennedy probably invented the term earthbag as well as contained earth, Paulina Wojciechowska wrote the first book on the topic of earthbag building in 2. Building with Earth A Guide to Flexible Form Earthbag Construction. Kelly Hart developed a massive online database of earthbag information that encouraged idea sharing. Kaki Hunter and Doni Kiffmeyer worked on a variety of projects after studying with Khalili, calling earthbag flexible form rammed earth. Their 2. 00. 4 book, Earthbag Building  the Tools, Tricks and Techniques is available as an ebook. Free online booklets have been developed by different authors, including Owen Geiger and Patti Stouter. These include structural research and field testing techniques developed for rural areas7A 2.

Hart, with Geiger9 encouraged earthbags development into different culturally and climatically appropriate shapes. Dr. John Anderton of South Africa has tested a triple channel bag version that reduces the slumping problems inherent in non cohesive fill material like sand,1. E khaya. Fernando Pacheco of Brazil pioneered the use of lighter HDPE mesh tubing for simpler hyperadobe walls. Rebuilding after natural disasters and in low income regions around the world has included earthbag. Although heavy earthen walls are usually dangerous in quakes, Nepals spring 2. Engineer Nabil Taha developed the first general specifications for one type of exterior pinning reinforcement appropriate for the highest seismic risk zones. Several engineering students have tested uncured or low strength earthbag, and Build Simple has tested cured cohesive walls1. Organizations building in Nepal are currently working with engineers to improve and refine reinforcement options for seismic resistant earthbag. Construction methodedit. Timelapse video of an earthbag building being made. Construction usually begins by digging a trench to undisturbed mineral subsoil, which is partially filled with stones and or gravel to create a rubble trench foundation. In high seismic risk regions a reinforced concrete footing or grade beam may be recommended. Several courses of gravel in doubled woven bags form a water resistant foundation. Each layer usually has two strands of barbed wire on top, that attaches to the bag to prevents slippage and resists any tendency for the outward expansion of dome or rectangular walls. Bags on the course above are offset by 2. Bags can either be pre filled with material and hoisted up, or bags or tubes are filled in place. The weight of the earthen fill locks the bag in place on the barbed wire below. A light tamping of the bags or tubes consolidates the moist clay containing fill and creates interlocking bags or tubes anchored on the barbed wire. Container typeseditSolid weave polypropylene is most popular, available around the world to transport rice or other grains. Polypropylene is low cost and resists water damage, rot, and insects. Tubes are often available from manufacturers who sew them into bags. Mesh tubes of soft crocheted poly fibers are also used, although stiff extruded mesh or woven mesh bags can also be used. Organicnatural materials such as hemp, burlap like gunny sacks can be used. Since these may rot, they should only be used with cohesive fills containing a significant proportion of clay that form solid masses when tamped. TerminologyeditEarthbag is now a varied family of techniques. Each type of fill and container has different strength and reinforcement requirements. For hazardous locations, accurate terminology is needed. Contained Earth CE is based on the original technique, but with specific soil strengths and reinforcement chosen for hazard levels.
