Below grade

Why the right trenching contractor matters

A trench can look fine once it's backfilled and still fail inspection or cause problems months later. Most issues start below grade.

Wrong depth or grade

Fails inspection and has to be reopened and redone.

No shoring or trench box

Unsafe excavation, OSHA exposure, and cave-in risk on deeper cuts.

Poor backfill & compaction

Settlement and cracking in the pavement or slab above the trench line.

Missed utility locates

Struck gas, electric, or fiber lines, project delays, and repair costs.

Uncoordinated tie-ins

Leaks, failed inspections, and rework on water or sewer connections.

No documentation

Disputes over completed scope and depths once the trench is backfilled.
