We deal with both the public & trade.

Clean crushed

We sell 6mm, 10mm, 14mm, 20mm, 32mm, 40mm, 50mm, 75mm or 100mm clean crushed.

Crusher Run

Crusher Run/ hardcore is a down to dust construction material. We supply three grades 75mm, 100mm or 125mm.

Dust

Dust is a natural byproduct of aggregate production and refers to the fine particles that are generated during the crushing and screening of aggregates. Dust is typically used as a filler which can help improve the strength and final performance of other materials.

Granular Sub-Base Type 1 (GSB Type 1)

Granular Sub-Base Type 1 is suitable for all sub-bases such as for roads, driveways, pathways and hard standing areas. The mixture of crushed stone and fines ensure that voids are avoided when compacted, resulting in a load bearing and stable surface.

Highway Spec aggregates

Our highway spec aggregates meet the stringent requirements and standards set by the Highways Authorities for use in road construction and maintenance.

Scalpings

Scalpings are typically derived from the process of removing the top layer of an existing road or pavement, usually during resurfacing or reconstruction work. This top layer, which may include asphalt, concrete, and various types of aggregates, is removed to prepare the surface for a new layer. The material that is removed is then crushed and processed to create scalpings aggregate.

Gabion Stone / Block Stone

Our Gabion stone is sourced from our own quarries and are used with wire backets or mesh cages for erosion control, retaining walls and other projects that require reinforcing earthworks.
