Are you looking to install a new gas line?
Trenching for a gas line is one of those jobs that looks simple, but can go sideways fast if it’s not done right! There are a few steps you need to take before trenching just anywhere.
Safety First:
It is mandatory in the US to call 811 before you dig. They will reach out to all the utility companies to mark their lines so make a clear digging area.
Permits and inspections are usually required.
Make sure to have a licensed installer for gas piping.
Pressure test needs to be done before backfilling.
No open flame, no shortcuts. Gas work isn’t DIY friendly!
Trench Depth:
Natural gas (poly/PE underground pipe): 12-18″ minimum cover
Metal pipe underground: 18″-24″ minimum cover
Sleeve under driveways/footpaths: required in many areas
Tracer wire: required for all PE gas lines
Materials Commonly Used:
Poly gas pipe underground
Anodeless risers at transitions to above ground
Tracer wire and warning tape.
Sand or fine soil bedding (native soil works), avoid rocks.
