Our range of concrete blocks are manufactured in Killarney, Co. Kerry.


Aggregates and water are mixed with a blend of CEM2 and GGBS cement in our automated wet batch process. The mixture is then fed into a Finlay block machine. The block forms produced are laid on our concrete block yard to cure, before being strapped and stacked. The concrete blocks are then stored for a minimum of 28 days, to allow them to attain maximum strength prior to being dispatched.
