Corrugated pipe is not meant to be sealed before backfilled. I did a ton of research on this during my last irrigation job. Once the trench is backfilled, the compaction is suppose to create the seal. I used 9x9 drain basins last time, and used blackjack roofing tar to create a water tight seal before backfilling the trench (for testing purposes).
