Doric Standars burial vaults are crafted of durable, strong reinforced concrete chemically bonded to tough Lustra-Tech®, Fiberlon® or Durapreme® plastic linings featuring Doric's exclusive strengthening rib design. These ribs are formed into the plastic to increase the load bearing quality of the vault. Doric double wall vaults are excellent values. The Doric Patrician® features a delicately marbleized carapace cover to match the vault interior. The Phoenix® has six attractive exterior lifting handles. Both have hand applied two-tone finishes that complement casket selection. The Tiara® and Titan® also employ the same reinforced concrete and ribbed linings but vary in their exterior details. All Doric double wall vaults offer an exceptional value.
