Plaster over DPM

[oasiz]

Hi folks, new here!

I'm looking to put plasterboard up in my integral garage as part of a mini conversion into a games room - I was wondering if the yellow sheet (see attached pic) is the DPM layer and if there's any problem with me plasterboarding directly on/over it and/or if it needs covering with something else first?

Information-wise, the image shows breezeblock, a concrete layer (which seems to have some silver/foil lining inside?), the yellow sheet and finally the floor. The bottom of the breezeblock is approximately the level of the main house (you step down into the garage) - and the external garage wall is thick (breezeblocks with stone exterior) - there's a bedroom above the garage, so presumably well insulated all around.

Appreciate your help!


Regards,

Rob

Hi - small correction, just felt what I assumed was the concrete bit (immediately below the breezeblock) and it's actually semi-flexible, some form of tough membrane?

OP,
The DPM(the membrane) should flop up the wall a little.
Fix your p/b over the yellow sheet. But keep the p/b about 35mm - 40mm from floor contact.
