Description & Application:

Pebble Dashing - Harling
Natural Perma Frost White Quartz and Volcanic Black Gravel specifically sized for the renovation of pebble dashing (harling) and for exposed aggregate concrete.

Historically the proportion of black to white chippings used for dashing can vary from 5% to 20%. Hence this renovation pack is supplied as a 3kg pack of black and 12kg of white chippings in order that a suitable mix can be established on site.

This product potentially contains small amounts of iron minerals which may cause staining when used as a dashing.

Coverage will depend on the skill of the applicator, the density of cover required and wastage during application. As a guide application rates in the order of of 5kg per sqm may be expected. ie a 15kg pack could be expected to cover up to 3sqm.

Product Imaging:
Clean gravel for product imaging and promotions. The semi opaque form of the white chippings provides the opportunity to highlight both applied light and base colours.

The black chippings provide a grey form when dry and a dark black when wet. Product may require to be washed with clean water before use to remove loose dust.

Decorative Plant Topping:
Striking black and white chippings for both internal and external plant topping.

When used externally the combination of Perma-Frost White, and Volcanic Black chippings provides for a striking plant mulch and product ideally suited to edging of decked areas.

The low water absorption of both components prevents algal and moss growth and the white spar lightens shady areas.

When used as a decorative mulch coverage of 0.7m² at 15mm thickness may be expected from a 15kg pack.

Historical Note: Harling
Harling 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 and is known as Pebble or Dry Dashing.

Traditionally the technique used lime mortar, but more recently cement mortars have been used to provide a provide a base course on which to stick the chippings.

Stone chippings, pebbles and even shells are then broadcast onto the surface and lightly pressed in to provide a durable weatherproof surface.
