At J&S McKee Ltd, we specialise in structural concrete and in-situ concrete works, delivering high-quality construction solutions across Northern Ireland and beyond. Our capabilities go beyond traditional civil engineering—we are passionate about concrete construction and building works that are built to last.

These projects showcase our ability to deliver complex concrete structures with precision, efficiency, and technical excellence.
Our experienced team is highly skilled in complex concrete construction, including the delivery of central core lift shafts, which serve as the structural backbone of multi-storey buildings. This is where our passion truly shines—bringing concrete formwork and structure to life, from the ground up.
