Boring under a road

[Rotor-Man]

Need to bore under a road [35-40 ft.] in a new subdivision to get water supply from one side to the other side for a system for the entrance to the subdivision.
Would you bore in a 4" pvc sleeve and run the main line and timer wire thru it, or bore the wire and mainline under the road without a sleeve. Any thoughts appreciated.

I would run the sleeve, make things a lot easier later.

Here in Fla soft sand it would be an easy job to do with city water pressure. But in your hard pan I would think you might need a borehog for the job. How are you doing this???

we would use an air mole. I have successfully moled a under a fifty foot wide road with a ditchwitch 3" mole.......... but absolutly use a sleeve

You are talking greek to me. I never heard of an air mole. We are lucky enough to jet under just about everything. In Fact we have to jet quickly so as to not wash away too much material.

Thanks

Do you need to get a permit to drill underneath it? The road is more than likely city/township/etc property--I don't know if the laws are different in your area.

An Airmole is a pnumeatic tool that is hooked to an aircompressor. You dig a start hole, point the mole, and on turn on the air.

They are handy unless they hit a rock (prevalent in the hard rocky soil in WA) and they can sometimes break through the asphalt.

Jetting would be impossible up here, I don't know about your soil. I can't jet more than 5-10 feet unless the sidewalk was bedded with non compacted sand.

An other option is to rent a directional boring machine (such as the ditchwitch 410sx with the rotowitch attachment) or perhaps look into the Borzit handheld directional bore.

I can think of lots of ways to get from a to b, and I can think of ways that murphy would end up laughing at you with most of them. Call a directional boring outfit and have them pull a sleeve back through for you. This normally costs me around $10 a foot and the guys I use don't mind porposing in and out. I dig a start hole at "irrigation" depth and they shoot down over and back up. On the far end, I just let them shoot out of the ground and pull the sleeve back through, then I dig down and cut the sleeve at "irrigation" depth again. Minimum hassle for the boring crew, so they are "nice" to you and they can guarantee they won't deflect off of a rock and end up going through or raising your ashpalt on the road.

I would find a direct boring for that bore. Here it would cost about 18 per foot.

[Flatbed]

I agree, get someone to bore a sleeve. Around here I can get a 4" bore for around $8 per foot and its worth every penny.

Thanks for the replys. Getting a 4" sleeve bored next week, sure would have been easier if the excavator had dropped a couple of 4" sleeves before they asphalted the road, but once again, do it quick and pay the price latter.

Isn't that the name of the game though? :)

I've been working on and off on a commercial assisted living job for the past 6 months, if the crew there would just actually work with us we instead of repeatedly screwing us over we would have been done long ago.

At least this one is just time and materials...their buck lost, not mine.
