What type of paving is this?

I don't do very much pressure washing, just the odd bit now and again so I am trying to double check this type is OK to pressure wash then hypo? It's only a small area about 25sqm for an existing customer.

Thanks for any suggestions.

Looks like Indian sandstone hypo it and pressure wash be careful with a turbo though as it can blow shale off the surface. It will come up like new
