Aggregates Cardiff - Quality Building Materials Delivered

Cardiff's diverse construction activity requires a broad range of aggregate types and grades. Major infrastructure projects such as road construction and utility installations need certified Type 1 MOT sub-base meeting Highways England Specification for Highway Works requirements. Commercial building foundations may require specific concrete mixes demanding precise aggregate gradations. Residential landscaping projects are more flexible, typically using Type 1 for driveways, topsoil for lawns and planting, and decorative gravels for patios and borders.

Type 1 MOT sub-base is our most frequently requested aggregate in Cardiff. This certified granular material — crushed limestone, granite, or recycled concrete graded to 0-63mm — provides the stable, well-draining base essential for driveways, car parks, and structural foundations. Cardiff's clay-heavy soils can cause heave and movement in poorly designed sub-bases, making quality Type 1 laid to the correct depth and properly compacted essential for long-term driveway performance. We deliver Type 1 in bulk tipper loads that can be spread and compacted directly to the specification depth.

Sharp sand is essential for concrete mixing and mortar preparation across Cardiff's building projects. Mixed with cement in the correct proportions, sharp sand produces strong, consistent concrete for foundations, paths, and structures. For block paving and slab laying, sharp sand provides the bedding layer that allows precise levelling before the surface course is laid. Our sharp sand is sourced from certified suppliers and meets BS EN 12620 for construction aggregates, providing the consistency that professional bricklayers and concreters require.

Recycled aggregates — crushed concrete and crushed brick from demolition projects — offer cost-effective alternatives to primary aggregates for non-structural applications. Cardiff's active demolition sector generates significant volumes of concrete and brickwork that we process into usable sub-base material. Using recycled aggregates for temporary site roads, non-structural fill, and landscape levelling reduces costs compared to primary materials while diverting demolition waste from landfill. This circular economy approach is increasingly valued by Cardiff developers with sustainability targets and BREEAM certification requirements.

Screened topsoil is a premium product that Cardiff landscapers, horticulturalists, and homeowners rely on for establishing healthy lawns, planting beds, and garden features. Our topsoil is screened to remove stones, roots, and debris, providing a clean, friable growing medium that drains well while retaining moisture and nutrients. The minimum topsoil depth for lawn establishment is 100mm — for turf that will receive heavy use or face challenging conditions, 150mm provides a better growing environment. Planting beds and borders benefit from 300mm+ topsoil depth for root development.

Delivery logistics to Cardiff require expertise developed over years of serving the capital. City centre sites often have restricted delivery windows — our drivers know the designated lorry routes, understand Cardiff Council's construction traffic management requirements, and plan deliveries to arrive within permitted access periods. For residential deliveries in Cardiff's suburbs, our drivers are experienced in placing aggregate loads precisely where required, minimising the distance materials need to be moved by hand and protecting driveways, lawns, and property from vehicle damage.

For large Cardiff developments requiring ongoing aggregate supply, we can establish a delivery contract that provides programme certainty and volume pricing benefits. Regular supply arrangements with major Cardiff contractors, developers, and housing associations ensure materials arrive as needed without repeated individual orders. Our planning team coordinates aggregate supply schedules with project programmes, ensuring materials arrive at the right time for each phase of construction — from sub-base for enabling works through to topsoil for final landscaping and handover.
