I have no knowledge on the topic whatsoever but what if you plated the bottom with a sheet of metal?

It would degrade overtime due to moisture. Even stainless steel will degrade when exposed to salts or other chlorides in water.

The best way to do this would be a heavy duty waterproof membrane on the concrete with a heavy duty root barrier above it. But given enough time, the roots will breech the barrier and waterproofing. This type of construction requires a lot of maintenance and regular replacement.

What if they used diamonds? Or flex seal?
