Infiltration Bed Compaction
Infiltration Bed Compaction
(OP)
I'm designing an infiltration bed for a residence. It includes AASHTO #3 stone and HDPE pipes and fiberglass catch basins. I've noticed that the pipe and catch basin manufacturers require that backfill around their products be compacted in accordance with ASTM D2321 (the standard for gravity-flow pipes). However, the DEP spec requires that the crushed stone in the bed be loosely compacted.
I know infiltration beds with stone and pipes are common. Can someone please explain what I'm missing, or how this dilemma is addressed?
I don't have a copy of 2321 handy. Does anyone know if it addresses loose compaction for infiltration?
Thanks, everyone for your time and help!

How would these options mesh with the manufacturer's spec to backfill and compact in accordance with D2321?
I'm afraid of getting into a situation where the warranties on the pipe and catch basins are voided because we specicied something other than what the manufacturer requires.
