Earthship Can Wall Construction In Steps
Constructing can walls in Earthships is an innovative and sustainable building technique that repurposes discarded aluminum cans, contributing to eco-friendly construction practices. This method not only reduces waste but also offers remarkable adaptability, allowing builders to create structures of various shapes with minimal technical expertise.
Adaptability and Ease of Construction
One of the significant advantages of using can walls is their flexibility in design. The lightweight nature of aluminum cans enables the formation of curved or straight walls, accommodating diverse architectural visions. This adaptability is particularly beneficial for constructing unique Earthship designs that harmonize with the natural landscape.
Moreover, building with cans requires relatively simple techniques, making it accessible to individuals with limited construction experience. The process involves basic steps such as crimping the bottom of each can to enhance mortar adhesion and adhering to the “two-finger rule” for spacing, which ensures structural integrity. These straightforward methods empower novice builders to participate actively in the construction process, fostering a sense of accomplishment and community involvement.
Construction Process
- Foundation: Establish a solid base using materials like cement or cob to ensure the wall’s stability.
- Laying Cans:
- Crimp the bottom edge of each cleaned can to improve its grip on the mortar.
- Place the cans horizontally into a layer of mortar, maintaining a spacing of approximately two finger-widths between them.
- Stagger the cans in successive rows to enhance structural strength.
- Mortaring: Apply mortar around each can, filling gaps and securing them in place, while keeping the exposed ends free of mortar for aesthetic purposes.
- Layering:
- Limit construction to two or three layers at a time to prevent instability.
- Allow the mortar to set before adding additional layers.
- Leveling: Use a level after completing each row to ensure proper alignment.
- Plastering: Once the wall reaches the desired height and the mortar has cured, apply plaster over the joints, leaving the can ends exposed if desired.
Conclusion
The use of can walls in Earthship construction exemplifies a harmonious blend of sustainability, adaptability, and simplicity. By transforming waste materials into functional building components, this method not only minimizes environmental impact but also allows for creative architectural expressions. Its accessibility to individuals with varying skill levels further promotes community engagement in sustainable building practices.
