I've done it. Glue outside perimeter with landscape adhesive. Use polymeric sand for the joints. The rain draining off the roof will cause you to refresh the polymeric sand every few years where it hits. Much easier than mortar.



I've been researching this myself. I read one article that suggested drilling holes (completely through to the dirt) in the existing concrete to allow for drainage.

Not sure how valid that approach is.

Drainage is certainly a concern. I was not comfortable with the pavers being above the slab lines and above the weep holes so I left a 2 foot gap from the brick for drainage and painted the concrete slab. The patio already had the proper tilt for drainage and is completely exposed with brick on 2 sides.

Don't do that. When water gets under concrete it will heave and/or crack.
