Bricks, Masonry, Asphalt and Concrete - wire under sidewalk

I need to run some tv cable and phone cable under a sidewalk from my house to my garage, whats an easy way to run it under my sidewalk without renting expensive equiptment.

At an expansion joint in your sidewalk, take a disposable carbo blade in your Skilsaw and expand the joint to a width of 3/4". Remove the concrete, excavate a tad below the bottom of the sidewalk. Lay your cable, then backer-rod the joint and fill with a good caulking.

Or, you could dig a hole on either side of the sidewalk and attempt to drive a piece of conduit through the soil.

I've been on several jobs where this was done using water hose pressure to help it along.

A neighbor of mine did it with water from his garden hose.

He dug a shallow pit on each side of the driveway. He then connected a female fitting to the pvc pipe and jetted it under his driveway. The right amount of water and pressure to force it under was the key. He went under the center of a section to avoid flushing water and soil out of a joint.

It took about 5 or 10 minutes to go under the 20' wide driveway and came out close enough to where he expected.

That is a good idea. I have run a 50' garden hose down a hole when I was a kid in the sands of Southern Mississippi (Grandma was none too happy), and in the Bahamas, they do that to set pier poles. In a clay soil it won't work very well, though.

Thats my problem here, it's all clay and rocks.
I was thinking of like some flexable drill attachment maybe might do the work for me.
