A Scrapper's Dream

We went from a very expensive plan to a simple solution because a security guard offered some common sense. Lesson - keep your ears open and never underestimate the contributions of others.

How much concrete are you thinking about? It sounds like the simple solution might be pretty costly. I don't have much experience with concrete, but I'm wondering how easy it would be for a large volume of concrete to cure. Also, how would it stress the tank itself while still in a semi-liquid state.[/I]

Too many unknowns on my end, but really don't like the sounds of the adding concrete to the tank to make a smaller tank idea. What's going back in the tank and what is that going to be used for? What happens if the concrete breaks down, crumbles? When it is time to remove everything what will happen? Will it end up costing your company big at that time? Be a hazardous situation?

Can the walls be shortened to make a smaller tank?

Really think you should just remove it and replace with new on this one. Don't try and invent in this situation.
