The finishing lift, 20mm capping to seal a fill, shed water and present a tight surface for the layers above.
Capping is the transition layer between bulk earthworks and engineered pavement: a finer crushed product placed over fill or rubble to seal the surface, shed rainfall and provide a uniform platform for sub-base construction.
The 20mm grading trims and compacts to tight level tolerances, the difference between a fill that survives a wet week and one that turns to porridge. Natural or recycled supply, scheduled with your bulk material so it lands in sequence.

Figures shown are indicative typical properties and vary by source; details for your delivery are available on request.
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.
