Had a poured concrete porch added to my house two years ago.
The original house had a 8 foot by 10 foot concrete pad in front of
the door with no roof over it. I concracted to have a hundered square
foot covered porch added. Contractor poured around the existing pad
but did not pin old pad to the new floor. Contractor did not do a
good job of preparing the base/footings for the new porch. Over the
course of the first year the back side of the new porch sank where the
land had been back filled near the foundation so an about 1 inch gap
appeared at the edge toward the house and at the edge of the old small
concrete pad some edges broke off and there was an about 3/4 inch
level difference between the old pad which had not sunk and the new
porch floor.Over the past year there has been no additional movement
of note of the new porch. I am told the only way or at least the
cheapest solution is to even out the height differences by covering it
with outdoor porcelian tiles. I am having the contractor repair the
porch but feel I would be better able to get the best job if I knew
more about the whole process. A google search lists mostly indoor
tiles and some outdoor tiles but could not find any information about
how to install outdoor applications. Am in North Carolina mountains
and the temperature extremes run between a low of say 10 F in the
winter to 95 F in the summer. There is some snow but not much. Porch
is covered so gets little of snow or rain except what might blow in.
Can any one point me to:

1. Good source of plain outdoor tiles

2. Tile installation tips

3. Any one do a similar job willing to share their experiences?
