Electrical conduit allows you to run cables outside, underground, and in other nasty places. Sometimes though you have to get cable into places that look impossible, such as under an existing concrete path or driveway that you can’t rip up. It’s not as hard as you may think. I used a technique called “water boring” to install a conduit under a concrete footpath in just a few minutes, without having to dig up the path.
