How to cut grooves in concrete sidewalk

- Shooter Dude -

- Nehmo - Use a diamond blade in a circular saw or angle grinder. An abrasive blade won't last very long with concrete, and the diamond blades are reasonably priced nowadays: about $25 for a 4 ½" diameter one.

In alternative, you could tunnel your way under the sidewalk with water pressure. Use a nozzle on the end of a rigid pipe or snake a regular hose through a length of PVC pipe. This method is used a lot for installing sprinkler systems. (I might go at 15' from both sides.)

I applaud what you are doing. I hate to see a dog on a chain.

Same here...a dog on a chain is a sad thing.

You can get devices with an implanted battery and high voltage discharge device... the battery recharges while your pet sleeps in his bed placed over a recharging mat.

The vet implants the sending unit in its testicles, or you can do it yourself if you are fast... then whenever yer beloved pet starts to get near the perimeter of the property the high voltage probes in its testicles are energized.

This is probably what I'd do... A garden hose under regular pressure will dig through the dirt with ease. I used to do this when I was a kid... my folks hated it. All those holes in the yard!

OUCH!!!!

What ever happened to the ones that just go around their neck?

Something that MANY folks don't consider as well... These radio fences MAY be good at keeping your dog in the yard (If you devote all the training time needed) BUT it does NOTHING for keeping other animals out. No amount of training will stop your pet from chasing a rabbit through the radio fence if they are going fast enough... and once out, they won't be able to get back in!
