Hi i have a garage which is single brick walled along teh back. it was plaster boarded with dabs and a large amount fo codensation formed. - i have not converting it myself into a room with heating etc. when i took the plasterboard off (which had lots of moisture where the dabs were)it was very wet and there was lots of condensation.
i have had a few companies out some suggest
1) old paint stripped
thin layer of render
tanking with a cementious mix x3 coats
plus DPC injection for added protection
2)just a membrane newton 5mm
3) both of the above - we are keen to go overkill to make sure no mositure comes through after it is converted
