aviation vaultPCC manufactures underground vaults servicing numerous operations such as telco and telecom cable runs, etc. Much lighter than the tongue-and-groove double sealed concrete vaults, the fiberglass vaults are unitized with no underground joints to leak.

  • Meet Tier 8 (12,000lbs), Tier 15 (22,500lbs) and when used in aviation applications can support passenger jets rolling over them.

  • Exceed ANSI/SCTE 77-2007 specifications and Western Underground Committee 3.6

  • Grounding lugs are standard equipment

  • Skid-resistant covers available
  • Lightweight compared to concrete having up to three times the compressive strength of concrete, no special water-sealants required to prevent water migrating through walls

  • Ideal for corrosion resistance and areas exposed to salt
  • Exceptional resistance to chemicals, fertilizers and sunlight

  • Can be made from non-metallic, dielectrically-resistant, and fire-retarded material, yet

  • Not affected by freeze/thaw conditions

  • Field-adaptable: Fiberglass requires no special tools

  • Many sizes and depths available, custom vaults and pits also available, either new or replacement parts for Highline, Hubbell, Dabico, Cavotec SA, Combibox and other manufacturers.
