And whats wrong with grout ??? Id of cut the old grout out, sprayed some expanding foam in, let it set (thats the secret) then just grouted it back up,been fine for ages

That's exactly what I thought and then read something about Dom being in the area soooooo.....

@John Benton i hope you don´t mind i share this in your thread, but since it´s related i thought it would be the right place instead of opening another thread.
This is a job that i did this year, it was a balcony in the attic of a house. The room right bellow the balcony had an infiltration and some of the mosaics on the balcony were starting to peel off.
Because the whole house as the same mosaics on the floor, the client wanted to stay the same.(It´s a discontinued mosaic) So i had to take all the mosaics and clean the adhesive behind . The funny thing is that the they did the waterproofing with fiberglass... the same that boats are build!(this helped me to take off almost the entire mosaics) First time i saw that !
After cleaning the mosaics and the floor i did the waterproofing with sikagard-570w (4 crossed coats) and then applied the mosaics with cross adhesive on the piece and the floor.
Because the client had saved 6 or 7 mosaics, i was able to do the job.
