Aggregates

Whitemountain is a market leader in the Northern Ireland quarry materials sector, operating several quarries in the region. We supply quality products such as high specification aggregates and sub–bases throughout Ireland, while exporting from our dedicated ship loading facility at Port of Belfast.


Our range of aggregates and sub–bases are suitable for use in highway construction and civil engineering projects, as well as in the production of ready mixed concrete and precast concrete.

Our High Polished Stone Value (PSV) Sandstone (+ 68 and + 65 PSV Litharenite) is in extremely high demand from export markets for use in asphalt surface courses, given its unique low abrasion and high polished stone values, which have led to its use on major highways in the UK, Ireland and Europe.

Our high specification aggregates are also an important component of our in–house production of asphalt and other innovative CE Marked surfacing products. All aggregates are produced in accordance with European Standards, with our quarries and products holding relevant CE Marking and Type Test Certifications. Whitemountain also operates under the ISO 9001 SGS certified quality system, managed by our UKAS accredited laboratory and Environmental and Quality department.
