Splice an Underground wire for light post


A few months ago we had a new walkway installed. They cut the wire that goes from the house to the light post in our front yard. The "fixed" it and buried it under the walkway, but they must have just used duct tape to splice the wires. Now the light isn't working so I'm guessing that their "fix" has failed over time.
My possible solution:
Cut the wire on both sides of the walkway, splice in a new longer piece of wire so that I can run it around the walkway, use heat-shrink tubing over the splice and re-bury the wire.

Should this work?

They make underground splice kits.

I got the parts last night at HD. Can I use a hair dryer for the heat-shrink, or do I get to buy a heat torch?

Thanks. It's raining for the next couple of days so I'll give it a shot this weekend. I spent $30 on materials, hoping to save the $100-$150 I was quoted by an electrician....(at a minimum).

a hair dryer may not work very good, some shrink tubing need at least 200F air. i always use heat gun or torch for those use

Heat gun, torch, lighter, matches, whatever. A hair dryer probably won't get hot enough. It's very important to fully heat the connection, since those splice kits rely on melting a sealant inside the shrink tube to ensure waterproofing. Err on the side of too much heat.

They should be in a box and a drawing of the location in reference to the placement that is put away in your house and yard file just in case you die or move there will be a record of where this splice is.

This is absolutely incorrect. You do not burry boxes and make treasure maps to find them. Use a rated underground splice kit and follow the instructions.

Ok thanks on the boxes but I still think the location of the splice should be drawn on a yard map with measurements to pinpoint where the splice is in case there's a problem later. It's called an as-built drawing after the work is done. It can be placed where the circuit starts or in a file that you should keep on your property.

Now we are talking about a damn yard lamp here not a high voltage feeder to a pmh in your back yard. In other words no reasonable human keeps freaking as builds of their home.
