Subterra Infraprojects LLP — Based in Mumbai, operating across India
Subterra Infraprojects was established to address a fundamental gap in infrastructure rehabilitation — the gap between what is recommended and what is actually required.
We operate at the intersection of specialist inspection and trenchless delivery. Our work begins with evidence, not with solutions. Intervention is a conclusion, not a starting point.
Decisions precede execution.
Inspection establishes facts.
Assessment defines risk.
Intervention follows only where it is justified.
When action is required,
we deliver with discipline,
clarity, and accountability.
Subterra undertakes trenchless rehabilitation only where inspection and condition assessment confirm the need for intervention. Our role is to ensure rehabilitation is appropriate, proportionate, and executed correctly.
01
Robotic CCTV inspection and condition assessment of underground pipeline networks. Defect classification to international standards.
02
UV-cured cured-in-place pipe lining for gravity sewers and pressure mains. Full structural rehabilitation with minimal surface disruption.
03
Localised sectional repairs where full-length rehabilitation is not warranted by assessment findings.
Installation is execution. Accuracy is the differentiator.
Operating environment
Operations are planned around Mumbai’s rhythms — night shifts, narrow lanes, live networks under active use.
Disruption is minimised because it has to be. Every installation is preceded by desilting, inspection, and sign-off. The sequence is not shortened.
