Alternative Bond Beam for Curved Structures

Forming bond beams for roundhouses and other curved structures is somewhat difficult. Here’s a brief description of an alternative bond beam that requires little or no formwork. It’s made with two layers of long poly tubes filled with stabilized soil (non-seismic zones) or concrete (seismic zones). Tubes could be filled 3″-4″ thick to save on … Read more

Earthbag Structures for Disaster-Prone Areas

Ever since the earthquake in Haiti we have been inundated with requests for information about using earthbags for reconstruction efforts. Owen Geiger and I have joined with Patti Stouter to assemble a coherent response to this need that is based on our understanding of the strengths and weaknesses of earthbag building, coupled with some knowledge … Read more

All-in-One Outdoor Oven, Stove, Grill & Smoker

Once you’ve built your dream earthbag house, you’ll need an efficient means of cooking. At our house, this includes an oven as one part of our outdoor kitchen that keeps heat out of the house. This latest project was a collaboration by Owen Geiger and Mother Earth News Magazine to develop a super efficient multiple-use … Read more

24” Earthbag Modules

Using a standard-sized module can simplify the building design process. An even two foot module, for instance, is easy to plot on graph paper. This makes it easier to draw plans and calculate materials and costs. Another benefit of 24” earthbag modules is increased overlap between courses. Many earthbag builders just fold over the ends … Read more

Filling Bags to Capacity

I’ve seen some photos lately of structures with ‘thin bags’ where the earthbags were not filled all the way. My recommendation is to tamp the contents lightly as the bag is being filled. This just takes seconds and ensures the bag is filled to capacity so you need fewer bags. Here’s the process: 1. Fill … Read more
