Installation by former vibrator gives a denser, more consistent and more repeatable installation. Mechanisation reduces the effect of different installers and, by eliminating the need for spiking between layers, means less likelihood of lamination or of tearing the mica sheet, both of which can lead to metal penetration. Less vibration by hand ramming also means less exposure to vibration white finger, an industrial injury triggered by using machinery.

Orane supplies vibrating hand-held equipment and associated tools – three-pronged fork, crescent and flat-rammer – for the compaction of dry lining and plastic material.
