I used both the peel and stick "blueskin" and the dimple sheeting. The idea was to have an impermeable layer on the buried ICF wall, but since nothing is perfect the dimple sheeting would not allow any hydraulic pressure to be developed against the wall. All the water would shed donw to the weeping tile at the footings.
