Abstract
Abstract A burial vault having preformed hollow fiberglas resin base and cover shells, the shells having fiberglas anchor loops integrally formed on their inner surfaces. The shells are filled with a cement-sand-stone composition that is mechanically locked to the anchor loops on the inside surface of the liners, the cementsand-stone composition including a plurality of straight steel wires of short length randomly disposed throughout the walls to increase the tensile strength and crack-resistance of the vault.
