Alternatives of Oil/Sand in Tank Ring Wall Foundations
Alternatives of Oil/Sand in Tank Ring Wall Foundations
(OP)
I know that using a fuel oil-sand mixture is not an environmentally friendly solution anymore inside ring wall foundations. One viable option that I have seen is a liquid asphalt-sand mixture. However, in this case, a suggestion has been made to use a vegetable oil-sand mixture because where we are located, we have an ample supply of vegetable oil at our disposable. Has anyone ever heard of doing anything like this before? My concern is that the properties of the vegetable oil mixed in the sand will not produce the same slope stabilization affects as the liquid asphalt. Are there any suggestions or other concerns here?

When you think about it, why is putting oiled sand under a tank environmentally evil, but using asphalt on roads is OK? They're basically the same.

NFPA-22 mentions using lime as an alternative, and a cathodic system can also be used. They also make tank pad products as a replacement for oil sand. I don't know that slope stabilization has anything to do with it if it's inside a ringwall.

We've put down aggregate base and had the bottoms of steel tanks corrode very quickly. I'd like to think the oil would of helped.
