Tank foundation
Tank foundation
(OP)
We have a concrete tank foundation that is out of the flatness tolerance specified by API 650.
What remedies are commonly used? We are considering a sand and bitumen layer to bring the flatness into spec, any comments?
Further, due to the location of the site and availability of bitumen, would it be possible to use old machine oil instead of bitumen for this solution?
Any advise would be appreciated!

If it's an existing tank, see API-653.

Also remember, depending on the unlevel condition, raising the tank elevation will affect pipe connections.
