now down to bare bricks some below ground level.

3)what adhesive on the tiles they are big 41 x 30 x0 . 6 cm red clay on back?[/img][/b]

hmm, looks like you got salts coming through the brickwork, gues it's a tad damp down there? it will need tanking:

this will stop the damp and moisture getting back through to the plaster work causing it to blow again.

do wait for a second opinion though before going ahead but fairly sure it's the best solution to your problem.
