Description

Grano to Dust 6mm

Grano dust is a crushed granite aggregate (0–4 mm) used as a compactable, permeable base layer. Its angular particles lock together under compaction to form a firm, load-bearing sub-base for block paving, stone slabs, gravel paths and artificial turf. One bulk bag of grano dust will cover roughly 8m² at a 50 mm depth, ensuring easy material take-off and consistent depth control. Clean, screened to remove excess debris, it provides a stable, smooth finish that resists wash-out and allows surface water to drain away quickly.

Features

High permeability: Rapid drainage to prevent water pooling and reduce frost heave.

Screened: Impurities are removed during processing to deliver a clean, consistent aggregate.

Stable sub base: when compacted it becomes a very stable surface that acts as a great base for a artifical grass or block paving.

How do I calculate how much grano dust I need?

Measure your area (m²) and decide on depth (e.g. 50 mm). As a guide, each tonne covers around 8m² at 50 mm. Round up to allow for compaction.

Disclaimer: This is only a rough guide and can vary from job to job.

Do I need a membrane underneath?

Not essential, but a permeable geotextile membrane will help prevent weeds and keep sub-base layers separate.

Can grano dust be used under artificial grass?

Yes, a compacted 50 mm layer provides a flat, well-draining base that supports synthetic turf.

What equipment do I need for compaction?

A plate compactor (minimum 100 kg) is recommended; spread in even layers and lightly dampen, then compact each layer until firm.

Will it wash away in heavy rain?

When properly compacted and edged (e.g., with kerbs or edgings), grano dust remains in place even under heavy rainfall.
