i'm referring to corner wall vertical construction joints and waterstop.


not base to wall

If that's the way you want to construct it, I would probably use a PVC joint with the seal on the outside of the wall with a bentonite rod in a keyway at the centre of the wall thickness.

You may want to put the joint in the middle of the wall rather than the corners.

With a 20' wall, depending on the reinforcing and forming available, you may want to construct it monolythically.

I believe that wall can be poured monolithically if the contractor has the right equipment. You could specify that you want it to be poured as a monolith.

I wouldn't want a joint in a tank that small. You lose much of the advantage of continuity around the corners. Pay attention to the reinforcement requirements for a liquid containing structure, and cast it in one piece.
