Codelsur Proyectos S.L. is the result of 25 years of successful business. A civil engineering company located in Ayamonte, but focused mainly on the regions of Extremadura and Andalusia, with experience in photovoltaic, building, construction, civil engineering and solar energy facility projects.

Company History

It was founded in 1985 by Santiago Rodríguez Díaz (CEO), who started as a sole trader and evolved it into the company it is today. With two tractors and many projects, the company’s first jobs were on agricultural and aquaculture sites. At this early stage, earthmoving work was the main focus. Over the years, CODELSUR has worked in a wide range of areas in the construction sector: civil engineering, hydraulic engineering, irrigation and building, both for public and private companies. Through CODELSUR FACILIDAD, the company undertakes and provides additional comprehensive services, including PROPERTY MANAGEMENT in Huelva and across Spain. The process has been geared towards sustainable growth and profitability, with the idea of building a long-term relationship of trust with clients.



CODELSUR is managing the implementation of an R&D&I management system in line with the UNE 166002 standard.

The implementation of an R&D&I management system will allow it to organise the corresponding activities and integrate them into the company’s general management.
