TCB Industrial designs and installs utility infrastructure systems that serve power, water, and industrial facilities throughout California.
Our crews construct and rehabilitate underground conduit networks, drainage systems, vaults, and containment utilities critical to plant and civil operations.
From high-voltage duct banks to storm drain tie-ins and process utility lines, TCB’s integrated civil and mechanical approach ensures all buried and embedded systems are built to specification, safely, and with complete QA/QC documentation.
Core Capabilities
Underground Conduit & Duct Banks
Multi-conduit electrical and communication systems, with concrete encasement, rebar cages, and grounding systems
Vaults, Manholes & Pull Boxes
Installation and setting of precast and cast-in-place utility structures, including embedded steel and access hardware
Stormwater & Drainage Systems
Catch basins, culverts, trench drains, and storm tie-ins meeting SWPPP and city design standards
Water & Utility Lines
Pressure and gravity lines, process water, service water, and cooling systems with integrated mechanical tie-ins
Containment & Secondary Systems
Oil-containment vaults, spillways, and drainage isolation systems for substation and industrial facilities
Surface Restoration & Grading
Pavement patching, asphalt repair, and compaction testing after underground work completion
Methods & Approach
Preconstruction
Utility mapping, potholing, and alignment verification before excavation
Execution
Excavation with trench boxes and shoring per OSHA standards; conduit placement and concrete encasement per client design
Inspection & Testing
Conduit mandrel testing, hydrostatic pressure testing, and continuity checks for electrical and water systems
Integration
Coordination with civil, mechanical, and electrical divisions for final tie-ins and backfill sequencing
