Introducing Earthship Alternatives: CMU, Formed Concrete, ICF, Earth Umbrella
In this video, we discuss alternative options to using tires in Earthship homes. While tires are structurally stable and durable, the idea of having walls filled with rubber can be a concern for some. We explore faster, easier, and potentially stronger alternatives that can be considered.
One suggested alternative is using dry stack block walls, as recommended by a website dedicated to green and healthy homes[^1^]. This method allows for the use of regular blocks without the need for mortar, making it a relatively simple installation process. However, if the site has slopes or if burial of the walls is planned, extra considerations need to be made for proper coating and excavation.
Another option to explore is the use of Insulated Concrete Forms (ICF), with different types of ICF block units available. While ICF provides thermal mass, which may not be necessary for an Earthship design, it does require professional assistance for pouring and potential challenges in case of a blowout during the process[^2^].
Using Concrete Mixer Units (CMU) is another cost-effective and self-installation option to consider. Traditional or dry stack, CMUs can be easily laid by homeowners without the need for tire-pounding labor. Depending on the size and usage of the structure, self-installing CMUs may be a viable choice, especially when combined with additional insulation methods.
Timber, as featured in various sources and books, presents another alternative worth exploring. However, the concern lies in the long-term durability of wood foundations when exposed to the elements. The lifespan of logs in the ground is uncertain and could present challenges for sustainable construction[^3^].
