To limit the probability of nail withdrawal, which could lead to the deformation or movement of underlay, which could lead to the displacement or cracking of finished flooring.

Where finished flooring is required to provide water resistance, this is to limit the probability of the ingress of water into the underlay and the subfloor, which could lead to:
