DPC's are called Barrieres anti-humidité.
Look e.g. here
Well-known brands are:
Hygrostop, Murtech, Rubson, Sanimurs and Technisec. Perhaps you also find DPM's (membrane anti-humidité?
) on their sites.
I've got no experience with inside DPM's (the membranes).
But, please, give your wall the time to dry!
In my house it took, in a similar situation, two years.
