Straight Versus Zigzagging Barbed Wire

Do not zigzag barbed wire between courses of bags, because this will lessen its tensile strength. A load (stress) on the structure, such as a hurricane, earthquake or differential settling, would tend to pull the structure apart as the slack is taken out of the wire. Zigzagging the barbed wire would provide more attachment points, … Read more

Dispensers Versus Uncoiling Barbed Wire by Hand

I’ve seen various barbed wire dispensers being used and have wondered what design works best. I started making a dispenser for our roundhouse workshop, but gave up when things weren’t quite working out. It seems easier to move the roll of barbed wire by hand to where it’s needed instead of using a dispenser. Also, … Read more

Corrugated Metal for Bond Beams and Wall Bracing

Our earthbag design team is busy creating home and shelter designs, as well as innovative building ideas for the reconstruction effort in Haiti. (See Kelly Hart’s Alternative Bond Beam and Lintel system, for one example.) As you’re probably aware, conventional bond beams and foundations are made with reinforced concrete, but these are costly, labor intensive … Read more

Earthquake-resistant Earthbag Building Details

There’s obviously a great deal of concern about the recent earthquake in Haiti. Disasters like this are all too common, and so we’re working hard to develop at least two low cost, easy to build earthquake-resistant earthbag house designs. We hope to be better prepared in the future with plans ‘ready to go.’ But in … Read more
