Industrial Earthbag Projects

Industrial earthbag projects include massive projects such as highway retaining walls.

Our focus here is on low cost, owner-built homes. From time to time it’s interesting to explore related ideas to see what’s available or going on. As we’ve reported before, there’s a whole industry that specializes in industrial earthbag projects using geotextiles or geosynthetics. Their primary journal is called Geosynthetics Magazine.

As our regular readers know, earthbag building is growing rapidly. It’s time to take things to the next level to speed this building method into the mainstream. I just wrote Geosynthetics Magazine and asked if they could refer me to a geotextile engineer who is willing to design a standardized polypropylene gravel bag foundation or gravel tube foundation for mainstream home construction. The intent is to come up with an owner-builder friendly design as a substitute for concrete foundations.

  1. I love to see civil engineers confident to use earthbag. I’ll have to look through Geosynthetics and find out exactly what sort of soil in what climate with what finish surface they used.
    Civil engineers know that earth in poly textiles can flex and make cheaper stronger walls than concrete. Now for architects to apply this.

    • Yes, it may take an engineer who specializes in this type of work to pave the way. We know it works. It just takes an expert in the field to get it code approved.

  2. When you say foundations, are you referring to the floor? I don’t believe you’re talking about the walls. If you are talking about the floor slab then what would go on top of it? Correct me if I’ve got this all mixed up. You covered one time about using scoria and sand and then setting tile on top of that then, sweeping sand in between the cracks etc. to secure each tile. Is this what you had in mind? Forgive me if I’m way off base.

  3. Here are some previous blog posts about earthbag and gravel bag foundations:

    Another Earthbag Foundation Method

    Seismic Resistant Gravel Bag Foundations

    Insulated Earthbag Foundations

    The subject is also covered in detail in my Earthbag Building Guide and DVD:

    • You can get code approval for rammed tire foundations, but I don’t know if gravel bag foundations have ever been approved (except in really lax areas). Kelly and I have been promoting gravel bag foundations for years and I would love to see a licensed engineer come up with an open source design everyone could use or learn from. This includes using regular gravel for most applications and porous lava rock for insulated foundations in cold climates.

      Not only are earthbag/gravel bag foundations super low cost and simple to build, another key advantage is avoiding/minimizing the use of concrete for environmental reasons. Also, owner-builders may not have the skill to pour concrete foundations. Placing gravel bags is about as simple as it gets, and the work goes quite fast.

      Geosynthetics Magazine is in contact with all the leading companies who work in the field and so maybe they’ll know someone who can help. It’s worth a try. If they can design million dollar industrial projects, think how easy it would be to come up with a generic house foundation.
