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.
