The wall panels are molded first using a special [[reinforced concrete]] mix. In addition to the usual cement powder, stone, etc., additional materials such as metal shavings or abrasive materials may be added to resist drilling penetration of the slab. Unlike regular concrete used in construction, the concrete for bank vaults is so thick that it cannot be poured. The consistency of concrete is measured by its "[[Concrete Slump Test|slump]]". Vault concrete has zero slump. It also sets very quickly, curing in only six to 12 hours, instead of the three to four days needed for most concrete.<ref>{{cite web|title=Discovery Channel (UK) How Do They Do It?

*A network of reinforcing steel rods is manually placed into the damp mix.
*The molds are vibrated for several hours. The vibration settles the material and eliminates air pockets.
*The edges are smoothed with a [[trowel]], and the concrete is allowed to harden.
*The panels are removed from the mold and placed on a truck for transport to the customer's construction site.
