From precision fiber trenching to full terrain restoration — we deliver complete underground infrastructure works as a professional subcontract partner.
Precision trench excavation and backfill for fiber optic cable routes, ducts, and protective conduits. We work to the route plans of telecom contractors and network operators, maintaining exact depths, widths, and bedding specifications.
Trenching and excavation support for underground power cable corridors, transformer pits, and substation approaches. We coordinate closely with electrical contractors to maintain safe, compliant working zones throughout the project.
Open-cut trenching and shoring support for pressurised water mains, distribution lines, and service connections. We provide careful excavation to protect existing utilities and ensure proper pipe bedding and surround compaction.
Gravity sewer and drainage trench excavation to precise gradients, with manhole pit formation and pipe zone preparation. Our equipment and operators handle both shallow and deep profiles in varied soil conditions.
Controlled layer-by-layer backfilling with appropriate materials, mechanical compaction to specification, and surface reinstatement of roads, paths, and green areas. We leave every site in the condition the contract requires.
