The fine single-size, 7mm screenings for drainage around pipes, fine concrete mixes and sprayed sealing.
7mm aggregate is a single-sized basalt screening, small enough to flow and self-compact around pipes and conduits, clean enough to drain freely. Plumbers and drainers order it by default for pipe surround; concreters use it for fine-textured mixes and toppings.
Like all our screenings it’s washed of dust, consistently graded from vetted quarries, and available by the tonne or truckload. It also serves as a sealing aggregate for sprayed bituminous surfacing.

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.
