GILLCON GROUP LIMITED

GILLCON Group Limited is a family‑run, multi‑disciplinary enterprise that has grown from its roots in the Donegal Gaeltacht to become a leading supplier of sustainable building solutions across Ireland. Drawing on more than 25 years of experience, the Group combines traditional stone craftsmanship with cutting‑edge concrete technology and renewable energy generation, offering a complete, environmentally‑focused construction portfolio.

Through Gillespie Quarries, GILLCON supplies premium cut stone – quartzite, limestone, sandstone, granite and decorative chippings – all sourced locally and delivered with a reputation for quality fitting and service. Its Gillcon Retaining Walls division has pioneered the Lock+Load and I‑Con systems, providing high‑capacity retaining walls and low‑height, fence‑integrated solutions that maximise space and aesthetic flexibility. In the precast arena, Gillcon Precast manufactures innovative concrete products using 100 % harvested rainwater and renewable power, ensuring superior performance with a minimal carbon footprint. Complementing these activities, Gillcon Renewables operates two Irish wind farms, generating 28.75 MW of green electricity and offsetting the Group’s production emissions.

Together, these synergistic divisions enable GILLCON Group to serve architects, developers, contractors and local authorities who demand high‑quality, sustainable materials and construction systems, all backed by a commitment to Irish craftsmanship and eco‑responsibility.
