DPC for a single block wall??

Yes it is fairly straightforward but time consuming. What you need to do using a masonry blade in a nine inch grinder, grind out the length of one brick at one end, slip in a piece of dpc(ie marley etc), fill the joint with sand cement mortar. Move to the other end and repeat and depending on how long the wall is one or two in the middle but no closer than two metres apart. Allow the mortar to cure for at least 3 days. Then grind out another set of random bricks. When you do the bricks next to ones you have already done mind to lap the dpc. By using this method the structural integrity of the wall should be retained
I think you're assuming that the damp is rising, and IMHO this is not the cause.
You have a wall that I surmise is never heated on either side, and one side is exposed to the elements. Absorbancy of the bricks depends on their type and age, and the type and condition of the mortar, so is it not possible that this wall contains a lot of water and that it never dries out?
Have you checked that that the roof isn't leaking onto the top of the wall?
Have you considered just rendering the wall and then applying some weather proofing?

Certainly sort the roof first, then see if the damp problem goes away.
