How do you keep your forms from sticking to the concrete?

Are you talking about using 'water stop'? I didn't know what that was, was hoping the waterproofer I was planning on using would keep the joint from leaking.

Can you better explain what your saying to do? Are you talking about using this on the foundation before I pour the walls? http://buildingmaterials.cetco.com/L...2/Default.aspx

The first link is what we refer to as "voclay" and will work, but you need the adhesive to glue it down, or you can nail it down.

AN easier option would be to look into "Sikaswell S-2", but I think it only comes in a "sausage" tube and you'd need a bulk gun to put it on.

I actually meant a pvc ribbed waterstop (search for WR Meadows waterstop) when I used that term. This would be poured right into the slab and extend into the walls, but ideally, it should be seemed together, or at least try to glue it........

The second link is nothing more than a band-aid IMO, and will need to be re-coated every few years. You could use a far superior product once, for a fraction of the price, and have far better results IMO, but you're still going to have to hope that the concrete itself doesn't leak through, which is why I offered the other, foolproof method: encapsilating the entire thing in a rubber membrane.........

You need rebar, and unless you can do it all in one pour or shoot gunite, jomama and concretemasonry are gonna say, "Told ya so" 450 gallons of water weighs almost two tons. All that weight is going to be pushing down and out. The deeper the tank of same size the more pressure at the bottom sides.

If you got to Farm and Ranch Supply Store or online, you can find a 4'X8'X2' deep stock tank that holds around 470 gallons. Various sizes; shapes, round, oblong, eliptical; materials, metal, plastic, resin, fiberglass are available. Pillows, or giant water bags, are available at military surplus outlets.
