Proper way to bury URD Cable?

[jjminch]

Morning. First time poster, fairly long time looker. I need to run power to my shop/barndo on my property, the run is roughly 325' from the meter to the building 200a panel.

With some calculations and electrician consult, the wire is sized at 250 MCM aluminum. It's going across a low traffic area with clay soil.

My plan was to do the trenching work and have the licensed electrician terminate connections at the panel. One electrician was adamant about skipping URD and using regular wire inside PVC conduit. He said that he repairs breaks nonstop and I will have issues in a few years.

One 10' stick of 2.5" conduit is $45 bucks at Lowes right now. I can't afford to not use URD.

What are some best practices when burying the lines to minimize risk for breaks in the line from rocks and other hazards? Backfill with sand? Can I use corrugated sewer pipe as a sleeve of sorts for the URD?

Suggestions welcome. Thank you.
