Boring a drainage pipe under a driveway
Posted on 6/23/20 at 5:36 pm

I need to bore/shove a drainage pipe under my driveway to prevent water from pooling up. Anyone have any DIY experience/suggestions? Found some irrigation tools for water hoses but they are primarily for sidewalk width, I need about 16ft. Wondering better options are available or have been used.

Check the grade of the area to the sides of the drive. A lot of times pipes sit too low if you go under the drive.
You could cut a section out and attach metal plate over it.
They also make some vehicle rated channel surface drains. You would have to rent a walk behind saw, cut concrete, mortar or adhesive drains in. Youtube it.

This would be the best option, easy to clean out too.

3/4" pvc pipe with fittings glued to the end for a water hose straight nozzle.
then dig a trench on side of driveway to give you room to slide the pipe just under the driveway. usually this requires at least a 4-5ft trench so the pipe can be pushed under flat and level rather then angling deeper.
add a fitting to other end of the pipe and connect your water hose then turn on water and slide the pipe under the driveway as the water blasts its way through
its a home made hydro blast tunneling device used by contractors to run anything under existing driveways from gas and power lines, to water and drainage lines

Well, a hammer is certainly not the best way. I know. I drove a pipe under my driveway during construction with a hammer and some rebar. It was exhausting.
The water jet rig is by far the preferred method. It works, but you have to be cautious of the amount of washout under the driveway and ensure the long small bore pipe doesn’t wander as it’s tunneling.
Of course, as already mentioned, you have to also check grade and make sure your drainage will actually flow and go in the direction you want. Good luck.

I've used those before to go under sidewalks for small irrigation pipe and its a PIA.

Under concrete? Yeah, you're renting a concrete saw and cutting a trench. I've done about 8 feet with a water bore and even then it wanted to come out over a foot lower on the other side. Forget 16' with that cheap method unless you are a glutton for punishment.

Never thought of this. I think this is the likely the best way. I have have been concerned on how to control the grade of the pipe while forcing it under the driveway.

I saw a video youtube video where a guy uses pvc pipe and then he runs his hose in it on jet setting and lets the water cut a whole through the dirt. Obviously you'll need pvc connections for that length.
ETA: never mind already discussed.

I don't know what drove me to finally create an account on TD and actually post something instead of lurk. Oh I remember, it's because I spent a weekend doing exactly what keakar, LSUtigermE, etc said to do with the water jet and PVC pipe.
It does work. I drove a 3/4" PVC pipe under a 9' wide driveway for an electrical raceway for a driveway gate operator. Like others have mentioned, you need to dig a pretty long trench to the depth of the concrete so you are driving the pipe in flat and it does not angle down (I did not and my pipe was about 20" down on the other side).
We also had a lot of pine trees in the vicinity so digging was tough (constantly cutting roots) and I'm sure I was hitting some under the driveway causing the pipe to deflect.
This was not happening by just pushing and forcing the pipe under the driveway either (at least my soil conditions didn't allow for it). I ended up putting a PVC Tee on the end, connected the hose at a 90 degree, and then put a PVC cap on the end so I could drive it with the sledge hammer. (Buy several caps because you will break some).
At the end of the day, it was a total pain but damn it was satisfying once I completed it.
I will attempt to post some pics...forgive me if they don't work. First post and first pics.

I can live with that. Thanks for having me. Love this board/site and hope I can contribute.

Water jetting will only work if it’s a sandy material. With drainage, you are obviously trying to get larger than a 3/4” pipe. Dig your trench level that you are using to shove the pipe and it will stay fairly level. For larger pipes, use a cap on the end of the pipe and drill a few very small holes in the end. Works better than those nozzle kits imo. I’d saw cut. If you have a brick house with some leftover bricks, saw cut the width of a brick and go back with a brick band. Will look better than a small piece of new concrete.

How much is a ditch witch to rent for the weekend? Do they make a professional type of thing you could rent like a ditch witch for small jobs like this? Cutting concrete never looks the same, the brick band is a good idea.
Is it possible to use something else to power the water her with like galvanized pipe? I’d think for over 4-5 ft as said something stronger would help get a straighter line.
Also, not sure if this is an option, but most people are worried about the pipe nose diving down. That would be ok if you started on your high side. So don’t start the jetting process on the side it’s draining to, start on the side it’s draining from. Then if you nose dive down worst case you’ll be going down with the flow of water you need.

16ft is a LONG way to bore under, baw. Just sayin'!
Posted on 6/25/20 at 8:14 am to AEXLSUTIG
youre going to need 4" min (6" better) for a storm drain pipe or else it will quickly clog. you arent going to DIY water jet 4 or 6" PVC under a 16' concrete driveway. understand that your driveway sits on top of compacted structural fill
as the others have said, sawcut and trench your drive, set the pipe, then backfill and re-pour. all of that can be done in one day. rent a concrete saw & jackhammer or hire somebody

WHY on earth is a drainage pipe/conduit under ALL driveways not already in ALL building codes ? A few dollars DURING construction would potentially save thousands at a later date ! Same with electrical outlets along the baseboard in ANY flood potential area...why not install outlets at light switch level ?
