Construction and Road Aggregates

The quality of the base limestone deposit at Bennettsbridge Limestone is typically 98% pure calcium carbonate. This purity combined with sophisticated production techniques enables us to offer a range of high quality aggregates.

We are NSAI accredited to manufacture aggresgates to: I.S. EN 13242: 2002 + AI: 2007 + S.R. 21-2014 + A1: 2016

Progressive stages of crushing and screening enable us to produce a wide range of aggregate sizes.
