Trenchless Pipe Installation (HDD)

Telemetry-guided bores & pipe bursting to avoid open-cut excavation and restore sites faster.

Preventive Maintenance & Rapid Repair

Planned upkeep, emergency mobilization, and critical component replacement to reduce outages.

CCTV Inspection & Leak Detection

4K crawlers, acoustic/pressure testing, and GIS mapping for data-driven decisions.

Pipe Rehabilitation (CIPP)

Cured-in-place lining & spot repairs to extend service life with minimal disruption.

Underwater Welding & Diving Support

Certified commercial divers for wet welding/cutting, anode replacement, splash-zone repairs, subsea inspections.

Project Management & Compliance

Permitting, stakeholder coordination, QA/QC, documentation, and standards alignment.
