HAVE YOU TRIED THE ARDEX DPM SANDWICH? 
ARDITEX NA is moisture tolerant, which means it can be applied below ARDEX DPM 1 C, direct to damp concrete. 
This allows you to maximise the coverage of ARDEX DPM 1 C by creating a smooth surface for your DPM.
ARDITEX NA can then be applied directly to ARDEX DPM 1 C without priming. 
The result is the ultimate moisture control system.
