I'm surprised at the use of concrete. I was assuming fiberglass, although that would create a lot of work to get the bark texture, I suppose.

He did use a mix of fiberglass strands and concrete for the bark. We'll use a similar setup for construction projects occasionally depending on what our structural engineers call for in their specs.

When I was studying glass design we would make molds out of a mixture of plaster and fiberglass. it's surprising at how much strength that stuff adds to a mixture.
