Historic use indicates that it is capable of service life well in excess of 60 years providing that exposure conditions are not subject to severe frosts or high concentrations of sulphur dioxide, and that good stone detailing methods are employed to give best protection from surface water ingress.
It is estimated that the likely weathering rate of this stone would lie between 1mm to 3mm per 100 years in normal exposure conditions.
