Hi Ban Aik,

Concrete was all site mixed...but the actual pour is underneath that rough rendering work. The wall will be covered in multiple layers of the black capillary mat that I used in the seedling house benches. The plants will mostly root into the mat but hopefully some roots will grab onto the rough concrete surface as well. All those little bumps on the wall are 1/4 bolts with rubber washers and anchorbolts mounted into the wall...hopefully they will be more than enough support for the mat but like I said, I wouldn't mind if the roots grab onto the cocncrete wall as well.

Tiles - Yep, terra-cotta, locally made (mainland). Every house here has some variation of these... lots of small companies making them. I'll take pictures next time I'm up there.
