I need to get a piper under a paved survace about 25 feet wide. A few of my buds have suggested that it can be done using a combination of water pressure and brute (like in sledge) force. Anybody ever tried this successfully? Any Tips?

My son does irrigation installs and repairs and he pointed out one of the problems with the water method. Our daughter's concrete driveway had a crack that he pointed out to me as well as the dug areas on either side of it. He said that if you are not careful you will wash a much larger bore under the pavement than needed leaving an unsupported void.
Just food for thought. He has the boring tools to do it right but usually it is not cheap.
How big's the pipe? What material?
1.5" galvanized steel
I would get a road bore. Bore under the road with a 3 or 4" and use that as a sleeve. Is it a state road? If so you will have to be at least 3 ft under the road. You can get a contractor to do this for you for around 500$ . It includes digging a fairly large hole on both side of the road to accept the road bore machine. YOur neighbors might have an existing sleeve you might be able to use .

So far, the prices I've gotten range from $1000-$1500.
I'd imagine you have the Blue stake phone number handy. I have seen the City, use a hydraulic jack set up, please note; they only had to go 5 or 6 ft. take care Jim J
In our area, a pneumatic boring machine, like this one, http://www.quantum.net.au/spone/PneuVibe/moles.htm is generally used for small jobs (the cable installers have several of these out there full time).
You can rent them (at least, we can rent them); but, by the time you rent the unit and a 150cfm compressor, you might as well got a hireling to do it for you.

Be careful, no matter how you do it. A cable co. here bored into the side of a 48" water main. Ate the road. Huge hole. Truck fell in. Very bad.

How many threads do you have going on this subject?
I thought I had only one. Does it look like there's another?
