Water tanks?

  • Can one make a water tank out of the material, and has anyone done this?

  • Air Crete is porous and will absorb water so you would have to finish the surface. Due to the low tensile strength of aircrete you would have to add a lot of rebar or better yet fibers if you want an above ground tank. I have not tested it for water retention on its own but am building a turtle pond that will be finished with a tadelakt (lime based) top coat.
