Harrington Concrete & Quarries sources and process a wide range of limestone and sandstone aggregate products for varied applications.

Limestone products are quarried from local sources across the Connaught region and are available for pickup or delivery from our depot locations in Claregalway, Castlebar, Kilkelly, Ballisadare and Aghamore.

Sandstone sand and gravel products are sourced and processed from local natural deposits, and are closely monitored and quality controlled at a fully accredited on-site laboratory based at the Harrington Head Office in Kilkelly, County Mayo.

All sand and gravel products are CE marked under the standard of IS EN 13242 for Unbound and Bound Aggregates, and Harrington’s high level of quality control is regularly audited externally to ensure these standards are maintained.

Harrington’s Agri-Lime is locally quarried from a rich limestone deposit with a naturally high calcium content. The limestone rock is then crushed and graded to fine particles and dust, and held in dry storage until final delivery.

Our Agri-Lime is tested and certified by the Department of Agriculture, and quality control is maintained by our in-house laboratory.
