Conversion of building existing internal wall no dpc

[daunker]

I'm about to start converting a block built milking parlour. Will be building internal walls with cavity from existing block, they will have dpc and the floor will have dpm and insulation then screed. However, there is an existing wall running centrally that I would like to partially keep. But it doesn't have dpc in it. Is this going to be a problem, is there anything I can do to it.

 

I'm primarily concerned about damp, but not sure if any other problems, they are solid 140mm blocks laid flat if that makes a difference. Only a couple of courses from ceiling so would save me a job if I didn't have to take down, but perhaps be safer to start again?

Cant see why it would be a problem to leave the blocks with no DPC if the wall is structurally sound. I would continue the DPM all up the wall and tape all joints - cheap fix and would do the job.
