I am setting up gutters on my house, and building a tank to have water
for the garden
. I have done quite a bit of research, and decided to go for a semi-buried ferro-cement tank, with a construction process very similar to that described in this document (http://www.itacanet.org/doc-archive-eng/water/Buried_water_tanks.pdf
I've dug most of the hole, but need to build walls and support them with earth to get a reasonable volume and water level compared to the veggie garden.
The idea is to do pretty much like on the pictures:
- build a brick (or stone ?) wall around the hole (with cement)
- Bring in quite a lot of earth to pile on the external face of the walls, for support.
- Coat the inside with a structure of metal rods, chicken
mesh and cement, like described in the document linked above. About 6-8cm total thickness.
I have however a few hesitations I'd like to clear before I continue with the project
- Does that look feasible given the setup ?
- Shall i build the wall with terracota bricks -- isn't there a risk of decay when in contact with soil/humidity -- or stones ?
- I am guessing about 10m3 of earth will be enough
to build the supportive slopes around the wall, does that sound right ?
- Anything else I should
be aware of ?
Thanks a lot for your help !
