Over the years, San Martin has played a key role in the development of the main projects in mining operation, construction and infrastructure both in the country and worldwide.

Our history begins in the 1990s, in the midst of a complex social, political and economic situation, when our founders decided to take up the challenge in the country and create a company specializing in mining services underpinned by strong moral values such as honesty, commitment and respect, and these values distinguish us today.

Over the years, San Martin became consolidated as one of the leading companies in the field of services in mining operations, construction and infrastructure.
