Doric Bronze Olympian® The Doric Olympian® burial vaults are unmatched in the burial vault industry today. Designed for families who desire only the best for their loved one, the Olympians® are known for their handcrafted beauty, superior strength and durability. The Olympian® vaults offer a fourth layer of material to surround the casket. This outer casing of durable bronze or stainless steel forms an extra barrier against the elements occuring naturally in the ground. Each Doric Olympian® is formed from the high strength 5000psi reinforced concrete, bonded to ribbed inner liner of fiber-enhanced Doric Fiberlon®. Bronze or stainless steel is then chemically bonded to the inner liner for additional stability. The entire unit is then encased in hand brushed and clear coated bronze or stainless steel.
