Crushed Limestone

Quarried from the high purity limestone reserve in Ardfert, our broad range of road and construction aggregates are renowned for their consistency and quality.

All of our materials are produced under an ISO 9001 quality management scheme and are available either from the quarry itself or delivered to our customers using our dedicated
tipper fleet.

Our reserve of limestone goes through extensive annual testing. We are fully certified to IS EN 13242: 2002 + AI: 2007 + S.R. 21-2014 + A1: 2016  which deals specifically with aggregates for unbound granular fill for use under concrete floors and footpaths.

Our staff can advise on the appropriate crushed stone product for your particular project.

Ardfert Quarry manufactures aggregates to the highest quality standards including:
EN 13242 Aggregates for Unbound and Hydraulically Bound Materials (S.R. 21)
EN 12620 Aggregates for Concrete (S.R.16)
EN 13043 Aggregates for Bituminous Materials (S.R. 17)
