About Company
United Maintenance and Contracting Company (UNIMAC) operates as a Class 1 heavy civil contracting firm in Saudi Arabia. The company handles complex infrastructure projects from start to finish—designing, constructing, and maintaining roads, airports, and highways. With more than one thousand employees and over seven hundred pieces of equipment, UNIMAC delivers large-scale projects with precision and reliability.
UNIMAC began in 1979 with modest resources and small projects. Through years of reinvestment and strategic growth, the company now boasts vast in-house capabilities. It operates its own asphalt production plants, crushed aggregate facilities, testing laboratories, transportation fleet, and a dedicated project studies and design department. These resources ensure UNIMAC can execute projects independently from conception through completion.
