Our story
Local craftsmanship, done the right way
CMC Surfacing and Groundwork Limited was built around a straightforward principle: every project deserves the same high standard of workmanship, whether it is a small garden path, a domestic tarmac driveway, a block-paved patio or a large commercial car park.
Founded by owner Ciaran McMullan, CMC brings years of experience working on tarmac and asphalt surfacing, block paving and other groundwork projects across Northern Ireland. Having seen first-hand the problems caused by rushed preparation, poor drainage and corners being cut, Ciaran set up CMC with a commitment to doing things properly from the ground up.
We take pride in honest pricing, clear communication and quality workmanship. Every project is carefully prepared and completed with attention to detail, creating surfaces that are built to look good and stand the test of time.
Based in Castlewellan, we work across Belfast, County Down, County Antrim and throughout the wider Northern Ireland area. Much of our work comes through recommendations from satisfied customers, which reflects the quality and service we aim to provide on every project.
