So, In summary: The pictures are of two different drainage plane products. Both appear to be improperly terminated or sealed at the top. One (the first picture) may possibly be improperly installed with the dimples facing the wrong directions. Of course, all of this is assuming these are not just scrap pieces left behind during backfill.
It sounds like my client should request some excavation for further investigation as well as some product information and assurance from the builder that these products are installed properly.
Thanks for all the input.
