Roadbases

	DGB20 - Densely Graded Base Course material with a nominal size of 20mm. A well graded product from 26.5mm to fine dust, compliant with RTA specification 3051 for DGB20. Base course for main roads, high traffic areas, residential subdivisions etc.
	DGS20 - Densely Graded Sub-base. Crushed Recycled Concrete, top particle size 26.5mm. Well graded down to fine dust. As above but as used for a sub-base.
	R2 SUPABASE - A cost effective Crushed Recycled Concrete (80% to 85%) and Brick (15% to 20%) base or sub-base course material. Suitable for car parks, hardstands, roadways and under paving etc. Complies with new R2 Spec.
	HARDROAD - A cost effective Crushed Recycled Concrete (50%) and Asphalt (50%) Base or Sub-base material. For rural service roads, fill under slabs, driveways, car parks etc.
	-53MM SANDSTONE - Crushed natural Sandstone, used as Sub-base material. Suitable for car parks, hardstands, roadways and under paving etc.
	-75MM SANDSTONE - Crushed natural Sandstone, used as Sub-base material. Suitable for car parks, hardstands, roadways and under paving etc.

Aggregates

	10MM AGGREGATE - Crushed concrete and brick, with minimal fines, with a nominal particle size of 10mm. For use as a free draining material, retaining wall backfill, under pipes, slabs etc.
	20MM AGGREGATE - Crushed concrete and brick, with minimal fines, with a nominal particle size of 20mm. For use as a free draining material, retaining wall backfill, under pipes, slabs etc.
	40/20MM AGGREGATE - Crushed concrete and brick, particle sizes nominally between 20mm and 40mm with an average of approximately 30mm. Minimal fines, perfect for back-fill behind retaining wall and site access roads, reducing contamination carried onto streets from construction / demolition sites.

Sands

ENVIROSAND - A crushed recycled Bedding / Fill sand, with better compaction than dune or river sands, ie, crushed particles giving better mechanical interlock than round grained sands. Suitable for use under slabs, pavers, and as pipe bedding, fill etc.

Cement / Water Modified

	WATER MODIFIED ROADBASES - Water is added to roadbase and mixed through a pugmill providing moisture consistent material thus reducing work time and costs during placement and compaction. (ONLY AVAILABLE AT CAMELLIA YARD) PREORDER ONLY
	CEMENT STABILISED ROADBASES - Cement is added to roadbase by weight through a pugmill to modify strength of layer of material – from flexible to semi-rigid to rigid pavements. (ONLY AVAILABLE AT CAMELLIA YARD) PREORDER ONLY
	CEMENT STABILISED SAND - Cement is added to sand by weight through a pugmill to strengthen material and assist in spreading and compaction in difficult areas. (ONLY AVAILABLE AT CAMELLIA YARD) PREORDER ONLY
