It would be easy to strengthen this greenhouse design with rebar. The same basic idea could be used to build low cost ferrocement housing, shop space, etc. by adding rebar, small mesh and cement plaster.
“A team of folks in africa make some 7.3m long ferrocement roof channels for placement on top of a CSEB (cement stabized compressed earth brick) house.”
“Total roof size 360sqm approx
1 inch wire mesh 22 gauge
Days worked so far: 34 working days till last layer on last section laid.
Total cost so far $2800 not including patio post rebuild. Also waterproofing and painting not included but whole roof is covered.
Check out my new how-to article at Instructables.com on building earthbag water tanks. I pulled together content from previous blog posts, added a drawing and edited everything into one concise article. Let me know what you think. Instructables.com is a major site that’s been very effective in promoting my natural building projects.
I wrote in a previous blog post how I’m loving earthbag water tanks. My fascination with these water tanks jumped up a notch after reading an article about the difficulties of building a concrete water tank. From what I’ve recently learned by visiting Vanuatu and assisting in water tank design and construction, I know earthbag water tanks are much faster, easier and lower cost to build than concrete tanks.
What’s the best, most efficient way to build water tanks? That question has been burning in my mind since seeing the extent of water shortages firsthand on my recent trip to Vanuatu. While looking and thinking about possible solutions, I’ve found numerous good ideas on the Internet such as this underground ferrocement tank made with mortar and chicken wire. This wouldn’t work in Vanuatu and on many other islands due to the rocky soil; however, it will work in many other areas. I love the simplicity of this method.
