Done Right, Done Safe
We approach trenching with a safety-first mindset. From locating existing utilities to shoring, sloping, or benching as needed, our crew follows OSHA-compliant excavation practices on every job. We work with local utility companies and city inspectors to ensure everything is properly permitted, marked, and approved.
Our trenching process includes:
Site inspection and utility locating
Accurate depth and slope measurement
Precision digging with minimal over-excavation
Bedding preparation (e.g., sand or gravel base)
Coordination with utility installation teams
Backfilling and compaction to meet code
Jobsite cleanup and surface restoration
