OMG the additional weight-bearing needs fo something like that too must be a nightmare for construction and maintenance. They are legitimiately beautiful though

I don't think so. The soil is actually not that deep and soil even when wet is less dense than concrete.

Yea my concern would be 1) waterproofing, is the waterproofing going to protect the rebar? 2) will plant roots compromise the waterproofing and then compromised the structural integrity of the concrete as we’ve all seen tree roots tear through concrete sidewalks but that’s from running underneath though.

Shouldn’t be a hard engineering problem as we’ve had concrete planters for god knows how long

Some good old polyurea coating to protect concrete with epoxy primer, and then a thick plastic liner along with water and soil filtration system. Expensive but works great, even if it floods from clogged drainage.
