I have friend that build about 5000 homes and put in both interior draing tile in every one and it was not an extra since it is cheap when you are standardized and do it during construction. He even periodically put in flexible plastic pipes in the bottom of the block cores and ran them into the rock around the interior drain tile to take care of any leakage ot condensation. Not one problem in any home.
If it is standard construction you have 4" of concrete over the drain tile and the tile is surrounded by aggregate to collect water fot the tile. If this is the case, a shallow nail will be no problem. I you have one of the after-thought "drain tile" systems you could have a problem. Also if you have archaic cast trench system along the along the wall that is common on some eastern states, this could be a problem.
