Harling or Pebble Dashing: Is a Scottish term describing the technique of providing a decorative waterproof render. The technique has also been adopted in other parts of the UK where it is known as Pebble or Dry Dashing.
Traditionally utilising lime mortar, but more recently cement mortars have been used to provide a base coat. Stone chippings, pebbles and even shells are then broadcast onto the surface and lightly pressed in to provide a decorative and durable weatherproof surface.
The technique has been used on buildings form modest sea-side cottages to famous buildings including the Great Hall in Stirling Castle.

Concrete Batching:
The product can be used for exposed decorative concrete mixes. As a direct replacement for builders gravel. When used for exposed polished flooring and worktops the quantity of granite will depend on the desired aesthetics and mix design.
Whilst being durable, concretes made with granite will require more work than marble or limestone aggregates to produce a polished finish. However, exposed (brushed) finishes often refered to as "grano" will have good anti-skid properties
