Replacing Natural Stone Mosaic Tiles

Customer called me to come look at some loose tiles, after inspecting them it was apparent that water had managed to get behind the tiles and turn there substrate to mush.  After removing the tiles I could see the old plasterboard was badly damaged and needed replacing.  Once all secure and fixed properly I managed to salvage the natural stone mosaic tiles and re-fit them.  You can not tell the area that has been fixed.
