Vault Backfill Upon arrival onsite, ESNW rep observed the contractor place the footing drain around the exterior of the footing. Rep observed the contactor placing a 4” perforated drainage pipe around the base of the footing, bedded in 7/8th inch washed rock. The washed rock and drainage pipe were wrapped in geotextile nonwoven fabric. ESNW rep observed the contractor placing another drain approximately 5’ above the footing drain, also wrapped in washed rock and geotextile nonwoven fabric. ESNW rep observed the contractor placing 12” lifts of grey sandy silt with gravel and compact it with a diesel sled compactor and a vibrating drum roller. ESNW rep took compaction tests and observed adequate compaction of at least 95% of the proctor at the tested locations. Please see map and table below.
