Find a contractor to bore it for you.

PVC method works. Just remember that you must tart out horizontal to end up horizontal. If you go in at a angle you will come out much deeper.

.The video shows to dig a trench and use some blocks to help keep the pvc horizontal.That would suck if I couldn't find it on the other side.

If you have a pressure washer, the wand is standard pipe thread.

1/4" I believe. (might be 3/8") Unscrew the shorter piece. screw in a 10' piece of the pipe from the hardware store.

Blast through under the concrete 10' from each side.
If your soil is sandy, you can get by with the PVC and garden hose
If you have black or clay hard packed soil this will work much faster than standard water pressure.

When the job is over you have a new long reach accessory for your pressure washer for blasting mud dauber nests off of the eves of your home.

Great idea here.

Your on the right track-dig out a good section and keep it level and you will be good to go.

Dig out the other side a little to help

Your method will work fine!! I haven't found anything better.

There is a walkway tunnel kit in the sprinkler parts section of Home Depot ($5); consists of a jet nozzle and hose thread beginning section. You cement these on either end of a 10-ft piece of 3/4" pvc pipe and connect to a garden hose. I used this set-up to make a big enough passage for a 4" piece of 12-foot long pvc to go under a deck section that was directly on the ground ( was for part of a french drain). You do need to dig back a little ways to come in fairly level. For your 20-ft driveway, you should be able to match the tunnel up from either side. You could also just go ahead and connect two 10-ft. sections and cement the kit pieces to either end then cut them off the ends when complete to leave the pipe as a conduit for your wiring.

Will look at this tomorrow.Thanks.

May try this as well.Thanks.

I have done a bunch of these. I choose a 20' joint of galvanized, a tee up to a hose fitting, a short nipple with a cap. With the water running, you and a couple of friends start to ram it in back and forth. If it is sand you will blow thru quick. The advantage to this rig is that if the concrete guy had a sloppy pour or a pocket of rocks, you can tap on the galvanized cap with a sledge to get it thru. Another tip is use a galvanized reducer on the tip, it will increase the pressure, and when it comes thru unthread it and attached your pvc with wire taped on if necessary pull it back thru.
