Romtec vaults are lightweight for ease of installation. The molded one-piece design can’t crack and leak. The impervious surface will not absorb dampness and odor like pre-cast concrete vaults. The vault is completely separate from the building’s concrete slab, so dampness and odor cannot seep through.

  • Material: rotomolded cross-linked polyethylene
  • Integral rib design.
  • Steel reinforced concrete center column
  • Includes center steel post and footing form
  • Material thickness: 3/8″ average
