The unique purple stone for the very extensive restoration undertaken over years at St David's was quarried at low tide at Caerbwdy Bay, a few miles away. A dangerous occupation in itself but even more hazardous was the journey up the cart tracks - carrying the stone on stretchers to the areas where it was worked.
It is also said that Ralph invented a unique formula for slow-drying concrete for certain repairs to the roof of the Cathedral
