Infrastructure

Infrastructure

Every engineering activity is wrapped with an idea, a design and a construction project. After the project on paper, SRI can help make the thought a reality by ensuring processes run efficiently, construction sites are safe and reliable materials are used.

SRI capabilities in terms of expertise, experience and state – of –the – art analytical equipment can undertake various type of studies related to research and analysis of various products including Cement, Building materials, Roadwork, Soil & Wood.
