It has a very good quality in that when it becomes wet the stones maintains a grip surface, even when sawn to a smooth face. 

 

Unlike the Chinese granite they've used in Douglas.

The Pooilvaish marble steps is an old wife’s tale. It’s too soft.

Surely the steps could be as soft as sandstone for the number of people using them???

 

Pooilvaaish stone is not soft (in stone terms). In the vernacular "it's as hard as fuck" sort of thing. So is Castle Rushen limestone of course, and that's not soft either. (Whereas Peel sandstone is soft).

Marble is less porous than limestone and as such is considered to be more durable than limetone. Both from the same make-up of calcite. Generally, Pooilvaaish limestone has not gone through the full metamorphosis of pressure and temperature to be considered as a true marble.

So Pooil Vaaish/Pooilvaaish stone is somewhere in between limestone and marble. And certainly not soft although it may well have other qualities that might not be 100% ideal for steps.

Certainly 20 years ago there are at least some steps, or parts of steps, at St Paul's Cathedral that could well be Pooil Vaaish.

I'm not sure it would last long in Strand Street, but . . . . . Pooil Vaaish has been used in the so-called Town Square. That's been there 25 years, although obviously relatively little walked upon.
