What do you mean by this? I bet you I can buy ten tons of water for way less money than ten tons of concrete, not only because you need lots of water to make concrete...
Apart from that, you need lots of dead weight just to hold the cranes in a stable position.
Did you read the article? The concrete block is supposed to be reused for a long period of time, that's why the guy said it's a long term return project.
Yes, did you? Did you also form your own opinion based solely on the article?

Every crane need a lot of dead weight for a stable position, don't see problems where are no exists. Concrete isn't a sustance which contaminate, is cheap and disposable in any quantity as byproduct in any fundition of steel. They all have beside mounts of concrete.
