Ballast can be used in standard concrete mixes for footings, slabs, posts, and general construction.

Day Aggregates supplies Ballast in 10 mm and 20 mm variants – 10 mm provides a smoother finish, and 20 mm suits deeper, stronger pours.

No, the high fines content makes Ballast unsuitable for drainage layers.

Gabion stone is used to fill wire baskets or cages (gabions) for retaining walls, erosion control, river works, and landscaping features.

Gabion stone is typically supplied in larger sizes, commonly 75–150mm, to ensure it stays securely within the basket while allowing good drainage and stability.

The correct size ensures the stone does not fall through the mesh and provides structural integrity. Larger, angular stone helps interlock and create a stable, long-lasting structure.

Yes, Gabion stone is free-draining, allowing water to pass through easily, which reduces hydrostatic pressure behind retaining structures and helps prevent water build-up.

Absolutely, while primarily functional, gabion walls and features are widely used in landscaping for their natural, robust appearance.

Typical applications include retaining walls, slope stabilisation, flood defence schemes, highways, rail infrastructure, and commercial or residential landscaping projects.

Day Aggregates supplies gabion stone in bulk loads, making it suitable for large-scale projects and trade customers.

Minimal maintenance is required. Occasional inspections of the gabion baskets and stone fill will ensure continued performance and stability.

Stone chippings are a versatile decorative and functional aggregate, commonly used for landscaping, pathways, driveways, drainage, and surfacing applications.

Day Aggregates supplies a range of sizes to suit different uses, typically from 6mm to 20mm. Smaller sizes are ideal for pathways and decorative finishes, while larger sizes are better suited to driveways and heavier-duty applications.

Yes, larger, angular chippings (such as 14–20mm) are ideal for driveways as they interlock to form a stable surface that can withstand vehicle traffic.

Yes, stone chippings allow water to drain naturally through the surface, helping to reduce standing water and supporting permeable surfacing solutions.

A wide range of colours and textures are available, from natural browns and greys to more decorative options. This allows specifiers, merchants and end users to achieve the desired aesthetic.

The quantity required depends on the area and depth of application. As a general guide, a typical decorative layer is 30–50mm deep. For more information visit our Aggregate Calculator

Yes, products are available in loose loads and bulk bags, making them suitable for trade customers, large projects, and merchant supply.

No, Breedon self‑binding gravel is not free‑draining and should be laid with a crossfall/camber to shed water into suitable drainage.

Breedon Golden Amber Path Gravel should be laid directly onto a Type 1 sub‑base, with a finished compacted thickness of 50 mm.

One tonne of Breedon Golden Amber Path Gravel should cover approximately 8 m², at the recommended compacted depth of 50 mm. For more information visit our  Aggregate Calculator

Yes. When correctly laid and water‑rolled, Breedon Amber Path Gravel provides a semi‑bound surface which is considered wheelchair/buggy‑friendly.

It can be used as flat roofing ballast, for holding down insulation, in a drainage system, and as decorative cover.

It can cover approximately 12.4 m² per 1000 kg, at 50 mm depth.

Yes, 20/40 mm roofing shingle is widely specified for green roof perimeters/outlets.

Day Aggregates supply Rounded Roofing Shingle in bulk bags and poly bags.

SuDS tend to use clean, no‑fines angular stone across layers (e.g. 10/63 mm lower sub‑base; 4/20 mm upper sub‑base; 2/6 mm laying course) to retain voids and store/attenuate water.

Our permeable paving aggregates are designed per BS 7533‑13:2009.

Permeable paving aggregates enable infiltration/attenuation, reducing runoff rates and burden on sewers in urban areas.

Yes, our Play Bark meets BS EN 1176, using the testing process BS EN 1177; critical fall height in excess of 3 m at 150–300 mm depths.

Day Aggregates’ Play Bark is made from 100% sustainably sourced British hardwood, sustainably sourced.

Play Bark can be raked to maintain depth and evenness. Additionally, it can be topped‑up periodically based on the activity and wear.

Play‑grade barks/chips are supplied clean and screened.

GreenPatch Cold Lay Asphalt is a HAPAS‑compliant, instantly trafficable cold‑lay asphalt for permanent pothole and patch repairs. It’s produced with recycled asphalt and a biodegradable softener (no petroleum cut‑back solvents).

GreenPatch Cold Lay Asphalt can be used for minor cracks, patches, and potholes; suitable for Type 2, 3 and 4, low‑risk roads per SROH, wheel‑track requirements and PSV 55 hardstone.

Yes, it is workable below freezing; the material won’t evaporate/wax with extremes; and bagged, the product offers around six‑month shelf life.

GreenPatch is DOT‑approved across jurisdictions and promoted as a permanent, no‑VOC patch solution.

Organic-Lock is an organic binder blended with crushed primary aggregate to form natural‑looking, erosion‑resistant pathways.

When installed to specification, Organic‑Lock™ stabilised aggregates meet ASTM F 1951 manoeuvrability for accessibility.

The binder forms a gel on contact with water, bonding particles while allowing infiltration, making this product effective on slopes prone to washouts or rutting.

Once laid, Organic-Lock™ requires low levels of maintenance due to its self‑healing. Occasionally, you may need to re‑activate with water, scarify, and re‑compact.

The binder makes the material resist erosion, reduces dust, and remains flexible (avoids cracking) while keeping a natural appearance.

Argex is a lightweight expanded clay aggregate – spherical pellets with a ceramic foam micro‑structure and rigid surface.

Argex is commonly used for floor levelling/insulation, flat/inclined roofs, soil drainage, green roofs/substrates, insulating blocks, and geotechnical backfill.

Argex is lightweight with good mechanical, thermal, and acoustic characteristics. Due to this shape, it also allows for excellent drainage. It conforms to BS EN 13055.

Using Argex will reduce earth pressure and settlements, making it useful behind retaining walls and bridge abutments, and in poor ground.

Loose bulk densities are often ~340–760 kg/m³ depending on the grade. Day Aggregates supplies Argex in bulk bags, loose, and poly bags.
