Footing forms and capillary Breaks

Hello all,
Build in climate zone 4A. Would it be a bad idea to use Fastfoot and the delta footing barrier? The fastfoot seems like a really easy way of forming the footer and the delta footing barrier is what I will rely on to keep water out of the foundation wall.
Anybody see any problems with using both like trapping water or anything?
Thanks in advance.

Mick,
Membranes like Delta's work regrdless of how the footing is formed up.
Malcolm,
Thanks for the reply. Yes I know the Delta will keep the wall dry but I was more concerned with the footing now being in a sealed bag that will forever be full of water? I don't think it is a problem beings that concrete on bridges is fully submerged in water but neither companies instructions recommend to use both.
Mick,
You only need to run the Delta over the area of the footing that is under the stem-wall, not the whole top - and if you are worried about the footing being encapsulated, just cut away the Fastfoot after the pour. But the concrete is quite content to remain wet without problems.
I’m not at all sold on the Fastfoot. Is seems like it works best for large footings, and would use a lot more concrete than necessary on the smaller ones used for houses. Forming and laying out the footings with 2"x8”s usually takes me a day by myself. It’s pretty simple.
Here is a product I have used ...

begreener,
That looks like a good solution, but to a different problem. The capillary break is to stop moisture moving up the stem-walls, not through where they meet the footings.
I thought the whole point of fastfoot is that it's vapour closed, so it acts as the water barrier. (As long as you detail the top of the footing when waterproofing the walls)
I looked it up, fastfoot rating is 0.06 perms.
So kind of redundant to use both.
But to answer your question, there's nothing wrong with encapsulating the concrete. It doesn't degrade from moisture or anything.
