Earthbag Building
Affordable Lava Rock Insulation for the Far North

Porous lava rock — scoria (cinders) and pumice — is an ideal building material. We’ve covered this amazing material many times on our blog, but I just learned something very exciting. It turns out scoria is available in Alaska, British Columbia and to some extent the Yukon. All these areas have cinder cones (a type of volcano) that produce scoria. This is great news because porous lightweight lava rock is a good insulator and also fireproof, rot proof, easy to work with and doesn’t attract pests. It’s affordable if there’s a nearby source to minimize shipping costs. So this discovery makes it practical to build lightweight superinsulated earthbag houses in Alaska and Canada.

Shelters for All Update — One Year Later
It’s been about one year since the Shelters for All $300 House design competition. (Earthbag building was the most popular building method.) Let’s look at the progress made since then. Two videos below show their work in Haiti and India.
