A storage vault includes an inner tank entombed within a concrete outer tank by first erecting a pair of sidewall forms on a base plate to create an open-top enclosure. The wall forms are securely clamped together. A layer of concrete is then poured onto the base plate and the inner tank is lowered onto the layer of concrete. Concrete is poured into the enclosure to entomb the inner tank while the bottom layer of concrete is still wet. The inner tank is restrained by a pair of reinforced hold-down bars extending over the top of the enclosure and having a pair of downwardly extending hold-down tubes which contact the top of the inner tank. A back hold-down bar is forced downwardly by a chain which passes over the hold-down bar and is fastened to the base plate. After the concrete has set sufficiently, the hold-down bars and tubes are removed and the holes created by the hold-down tubes are filled with concrete. After curing, the wall forms and base plate are removed from the vault created within the form assembly.

A method for entombing a container within a homogenous layer of concrete comprising the following steps: selecting a container having a container top; placing a base plate on a support surface; positioning wall forms on the base plate; fastening the wall forms to one another to create a sidewall form; positioning the sidewall form relative to the base plate wherein the positioning of the sidewall creates an open top enclosure bounded by the base plate and the sidewall form; pouring a first portion of concrete onto the base plate to form a bottom layer of concrete in the enclosure; lowering the container into the enclosure until the container rests on the bottom layer of concrete to define a region within the enclosure surrounding at least a portion of the container; vertically restraining the container within the enclosure, such that the container contacts the bottom layer of concrete subsequent pouring of concrete; pouring a second portion of concrete into the enclosure in the region surrounding the container to contact the bottom layer of concrete before setting of the bottom layer of concrete wherein the first portion of concrete and the second portion of concrete form a homogenous entombing layer of concrete about the vertically restrained container; allowing the homogenous layer of concrete to set; and removing the wall forms and the base plate from the concrete encased container.
