Invisible pet fences are a great way to keep a pet contained in a specific area without having to get expensive permanent fences built around the property. While installing an invisible fence may be quite an easy task for do-it-yourself aficionados, some areas may prove to be a bit challenging. Burying the wire under a concrete driveway may be one them.

Things You'll Need

  • Invisible fence kit
  • Screwdriver
  • Waterproof caulk
  • Caulking gun
  • Chalk
  • Circular saw with concrete cutting blade
  • Safety glasses
  • Concrete repair compound

Check if your driveway has a seam or an expansion joint conveniently located in an area suitable for the underground fence. If so, use the screwdriver to remove accumulated debris trapped within.

Bury the boundary wire in the expansion joint pushing it down carefully with the screwdriver. Once it is in place, caulk over the wire using a caulking gun and a good brand of waterproof caulk.

Use some chalk to mark a line should your driveway not have a seam or expansion joint. In this case, you will need to use a circular saw equipped with a concrete cutting blade in order to bury the wire.

Wearing your safety glasses, make an inch-deep (or more, if required) cut following the line. Remember to allow the circular saw to rest every few minutes to avoid overheating.

Bury the wire making sure it fits in snug and deep. Use the screwdriver to push it down as needed. Caulk over using the concrete repair compound. Allow it dry.

Tips & Warnings

  • You can also use a high pressure hose to remove debris trapped within the seam or extension joint.
  • If you are afraid of making a mess when caulking, use masking tape to cover both sides of the cut for a neat finish and remove it once done.
  • If you do not own a circular saw, consider renting one at your local rental yard.
  • Keep in mind that in order for the caulk to set, the temperature has to be above freezing.
  • Always protect your eyes with safety glasses when using a circular saw.
