Is there any way to seal/waterproof behind natural stone, without using concrete blocks? My house is T/F and part of the house is to be faced with local stone (PP Condition). There is a section of the house, where roof is cut away, with very little room for same, ie., I don't have enough room to put blockwork - to seal the area - and stone on top of it.
1. Is there anything else I can use instead of the blocks?
2.What are the implications of putting the stone on with nothing behind it, stone being porous?
