How to Bury a Comcast Cable

When you need to bury a Comcast cable line, there are a few steps you should take to make sure the line is buried safely and securely, protected from future damage. Depending on the length of cable, you can dig a narrow trench with hand tools, or use power equipment for big jobs. Either way, the basic steps are the same.

Step

Contact the power company and ask for a technician to mark the location of any underground electrical cables before you begin this project.

Step

Measure the distance of the cable line to be buried.

Step

Buy 1-inch diameter PVC pipe to extend the length of the cable line to be buried. You can buy pipe in sections and piece it together later using connectors. Piping and connectors are available at large hardware stores.

Step

Dig the trench in as straight a line as possible, using a hand shovel for short distances or a powered trench digger for big jobs. Trench diggers can be rented for a day or in some cases by the hour from power equipment rental centers. A garden tiller with the two outer tines removed will also work if trench depth is not a major issue.

Step

Make a trench at least 4 inches wide and 8-12 inches deep for the length of the cable to be buried.

Step

Thread the cable through the PVC pipe and lay the pipe in the trench, adding sections of pipe as necessary with snap-on PVC connectors. The PVC pipe protects the cable, preventing rot and moisture and preventing accidental damage from gardening tools.

Step

Cover the trench with dirt, stamp it down and spread grass seed, if desired.
