Method for entombment of tanks in concrete

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 said positioning of the sidewall creates an open top enclosure bounded by the base plate and the sidewall form;
• pouring a layer 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 during subsequent pouring of concrete;
• wherein the vertically restraining step includes the steps of:
• positioning a hold-down member over the open top of the container so as to overlie the container;
• connecting the hold-down member to the base plate and;
• forcing the hold-down member against the top of the container;
• pouring 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 to form a homogeneous entombing layer of concrete about the vertically restrained container;
• allowing the concrete to set;
• and
• removing the wall forms and the base plate from the concrete encased container.
