FP McCann’s stone is renowned for its quality, purity and durability, hence its demand in commercial projects, such as rock armour and bridge construction.
The rock armour is extracted from our Clarkes Quarry in Lisnaskea, Co. Fermanagh. The limestone is a sedimentary rock with good ‘flaggy’ characteristics for the production of armour. It enables two distinct rock sizes to be produced.
