The structural cap, 40mm capping where the fill below needs bridging as well as sealing.
40mm capping does the same job as its 20mm sibling with more bite: the coarser grading keys into rubble and soft fill below, bridging weak spots while still trimming to a workable platform. It’s the standard first cap over deep or variable fills.
Used through subdivisions, industrial estates and road projects across Victoria, typically followed by a 20mm cap or directly by sub-base. Natural and recycled options by the truckload.

Full loads to open sites, sized to your access and the day's program.
Maximised payload where site access and mass limits allow it.
Every load GPS-tracked from the weighbridge to your gate, with the tonnes on the docket.
Placed and compacted to stabilise variable ground before pavement works.
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 200 mm deep = 20 m³ × ~2.1 t/m³
