In order to minimize vibration the balance should be located on a heavy table, preferably
marble. Ideally, the balance room should be located on the bottom floor, on a concrete slab
that is isolated by a shock-absorbing material from the rest of the foundation/ground floor
slab of the building. In addition, if the balance and table are not on a slab, it may be
necessary to reinforce the floor upon which the table is placed.
