Earthbag Building Basics is a simple poster covering some of the most basic aspects of earthbag building. It can be translated automatically with the Google Translate button. A PDF version of the same poster can be seen here.
Step by Step Earthbag Construction The basics of filling and laying bags are demonstrated in 8 easy steps, complete with videos showing exactly how to do things.
Temporary Wall Construction shows a crossection of how a tarp roof can be attached to the wall, with temporary wall protection, and berming to keep water out.
Raised Floors for Tents described a simple way to use earthbags for strengthening the sides of tents and raising the floor level.
Wall Reinforcement describes various ways to reinforce earthbag walls in key locations, including corners, to resist lateral movement.
Openings in Walls discusses ways to safely make openings in walls: reinforcement, lintels, window grills, vent block and pipe.
BOND BEAMS: Concrete, Tubular Steel, Corrugated Metal, or Tubular Bag
Earthbag Modules advocates the use of 24" modules for earthbag lengths.
EB Options for Nepalis a draft set of specifications for earthbag building addressing various levels of earthquake risk, prepared by Patti Stouter of buildsimple.org in response to the need for this information in Nepal after the devestating earthquakes in the spring of 2015.
Reinforced Earthbag Specifications is a 6-page PDF describing in drawings and text exactly how one might construct a reinforced earthbag wall that would pass most building codes in areas of high seismic risk. This document was prepared specifically at the request of Dr. Owen Geiger and Kelly Hart (who manage this website) for use on reconstruction projects in Haiti, but it could be useful wherever reinforced vertical wall structures may be built. We want to acknowledge and thank Nabil Taha of Precision Engineering (www.structure1.com) for his patience and diligence in preparing this document.
Vibration Damping for Earthbag Walls in Seismic Regions by Patti Stouter.
SITE WORK: Figuring Soil Needed, Grading for Drainage, Footings, Cisterns shows how excavation for buildings and and cisterns can provide the soil for filling the bags.
Earthbag Foundation outlines the steps in preparing an earthbag foundation for a floor system.
Earthbag Housing: Structural Behavior and Applicability in Developing Countries by Bryce Daigle. This thesis explores the structural behavior of earthbag housing under vertical compressive loading, in an attempt to broaden our quantitative understanding of this alternative building technique. Furthermore, this technique is assessed, along with other alternative construction techniques, for suitability in southern Sri Lanka, an area heavily damaged by the 2004 Indian Ocean tsunami.
Prism Testing of Polypropylene Earthbags A prism test was conducted on earthbags using three different types of fill: sand, rubble, and dirt. The tests gave us the failure stress of the bags with the different types of fill (43.06 psi, 57.84 psi, and 311 psi respectively), as well as providing deflection data on the earthbags. These tests were conducted at the West Point Military Academy Engineering Department.
Earth Architecture and Ceramics: The Sandbag/Superadobe/ Superblock Construction System by Nader Khalili (Cal-Earth Institute) and Phill Vittore (Structural Engineering Consultant),1998. An article outlining the chronology and results of testing done on Nader Khalili's superadobe system of building.
An Amazing Experiment If anyone had any doubts about the strength and integrity of this system of building, this experiment should allay those concerns. Earthbag building of this sort can be STRONG!
Friction and Tensile Strength of EB Components by Patti Stouter explains some of the current understanding of engineering related to earthbags based on other earthen techniques and personal experiments.
Cyclic Simple Shear Tests on Base Isolation Using Soilbags Soilbags have been understood to have the effect of vibration reduction and can be used as a kind of base isolation in building foundations. In this paper, a series of cyclic simple shear tests were carried out on soilbags filled with three kinds of soils under different vertical stresses to investigate the damping and stiffness characters of the soilbags. The results show that soilbags have a relatively high damping ratio and variable horizontal stiffness so that they can be used as base isolation materials.
Structural Information for Earthbag is a detailed description and evaluation of testing done on earthbag assemblies over several years by both educational institutions and Patti Stouter, the author.
