To build a reinforced concrete vault is a costly and lengthy project. This normally has to take place when the building is being constructed. It means that the vault is permanent and is lost, should the need arise to change premises.

The installation of a demountable vault is considerably lower in cost than that of a reinforced one. It can also be constructed in a relatively short period of time. Should the need arise to move premises it is a simple task to dismantle the vault and reassemble it at new location.

A demountable vault can be designed to meet the size requirements of the client. The only limiting factor being the load per square meter that can be carried by the building floor. Allowance is made for the provision of ventilation, lighting and any electric security devices should they be required.
