The structural screening, 14mm single-size for concrete that needs body, and drainage that needs flow.
14mm aggregate steps up the particle size for structural concrete mixes, high-flow drainage and sealing work. The larger stone gives concrete more body with less cement paste, and creates bigger voids in drainage applications where water volume matters.
Washed, single-sized and angular, it’s the standard coarse aggregate in many 25–40 MPa mix designs and the workhorse behind retaining-wall drainage and soak pits. Supplied alongside 14/10mm blends where specified.

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.
Dust-extracted and consistently graded for concrete, drainage and sealing.
As a guide, this material weighs around 1.5 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.
