Class 2 40mm Crushed Rock
Class 2 performance in a coarser grading, for deep lifts, heavy pavements and the layers that do the structural heavy lifting.
About this product
Class 2 40mm carries the same quality limits as its 20mm sibling, fully crushed, controlled plasticity, dense grading, but with a larger top size that suits deep-lift construction and lower base layers. The coarser skeleton gives excellent stability under construction traffic before the upper layers go down.
It’s typically placed as the lower base in thick pavement designs, on haul roads, and under crane and equipment pads where layer thickness matters. Available plain, wet-mixed or cement treated, weighed and tracked load by load.

How much do you need?
As a guide, this material weighs around 2.1 tonnes per cubic metre. Multiply your area by the layer depth to get the volume, then by the density. Tell us the area and depth on the quote form and we will convert it to tonnes and price the delivery for you.
100 m² at 150 mm deep = 15 m³ × ~2.1 t/m³
