40-75mm Aggregate

Our 40–75mm Drainage Aggregate is a coarse, open‑graded stone produced through controlled crushing and screening to deliver exceptional free‑draining performance. Its large, uniform particle size makes it ideal for high‑capacity drainage applications, including soakaways, attenuation and infiltration systems, land drainage, filtration layers, embankment drainage, and general civil engineering works where rapid water flow and long‑term ground stability are essential.

Available for collection or delivery within a 50 mile radius of our Howley Park and Fletcher Bank quarries.
