A good laboratory has got the pivotal role in assessing the basic parameters for any engineering design. As a responsible infrastructure consultant Caritas felt the necessity to established itsin-house laboratory for obtaining a confident engineering parameters accurately, quickly and cost-effectively.

We contribute services to the infrastructure projects for Central and state Government organizations, Indian Railways, PSUs and others. With many years of experience combined with a talented team of extremely creative people, Caritas is ready to help. We have a team of almost 10 laboratory and field staff, expert in his own work ant ready to take a new challenge every day. Our flexibility and client focused approach has opened up many opportunities and allowed us to work on some of the nation's prestigious Road and Rail Projects across the India.

CARITAS Material Lab offers numerous mobile field and lab testing facilities and equipment for prompt and accurate analysis of all your civil engineering materials – for highways/railways through bridges and tunnels to other public, commercial and private structures.
