As as the title, I have a single brick wall outhouse. This issue is water seems to easily penetrate all the way through and cause damp. I'm looking to build another wall inside to create a cavity.
I'm not sure 100% the best way to go with regards to the damp proof membrane.
Option 1. Line walls with damp proofing membrane going about half meter into the room floor level. Lay floor membrane on top going half meter up the wall. Build wall leaving 20-40mm cavity. 2 blocks up fix membrane into the brick work.
Screed floor.
Option 2: do the above without wall membrane.
Option one I'll insulation, option 2 I'm not sure as it might pass the damp.
Thanks for any help
