Hardpan! How can I not forget that, being from Kelseyville. Now, here in Sandy Florida and thanks for the advise. Need to run 18' under a driveway! Remember, you're just one cast away...
I'm about to try that pressure washer set up under a corner of my concrete driveway. 4 inch drain line is what I'll be trying to install. Hope it works.
Interesting and useful video!! Thanks for uploading and sharing. Question - when using the hose or a power washer, is there a risk of washing out too much dirt under the path causing a cavity to remain?
Thanks. It usually makes the hole slightly bigger than the pipe. I’ve never had problems with concrete cracking. The deeper you dig your trench and start you pipe the better for supporting the concrete.
Good video, I appreciate multiple options of digging the tunnel. How wide of a driveway do you think this would work for? I'm guessing no more than a single, it would get pretty hard.
The last method I mentioned will work for a 2 car wide driveway. It is more difficult the longer the run under the concrete. It might take multiple attempts
what do you use on the end of the pipe to that it isn't an eyesore? My project is to remove the tons of rainwater that comes off my roof so to help protect foundation.
All fine and dandy until you hit rock. Most walkways have some sort of foundation. If that happens you have to do method 1 with a small hole shovel. I also had to use a ramming bar because I had random 6-8 inch rocks in the ground. This will be great fun as you lie in the mud trying to bust up a rock 2-3 feet from you. If you don’t mind getting dirty and doing some hard physical labor then it is really satisfying seeing the pipe emerge from the other side.
By foundation do you mean a gravel bed? Yes sometimes you may hit rocks. If that happens you can use a steel pipe slightly bigger than the pipe you are installing and pound that rock out of the way. They do make a special tool called a bullet mole that can push or split the rock out of way. Check It out bulletmole.com
This hammer+hose method is (hopefully) what I've been looking for. I'd seen hydroexcavation in a lot of videos, but my walkway doesn't have a strong foundation and I'm worried about washing away too much dirt.
@@TheUltimateHandymanKyle it worked pretty well! I didn't have a pressure washer but a normal hose + drain snake worked for clearing out the dirt in the tube. Unfortunately I wasn't down deep enough and the pipe turned upwards a bit, so I ended up messing up the brick a bit anyway. Very solvable. Thanks for the video!
Can u do this water technique underneath pavers??? Or will all the mud compromise the integrity of the soil underneath and cause problems with my pavers?? Thanks!
I think it would cause problems for pavers. It might make them skink some. It could be possible if you start the pipe deeper in the ground like 2 feet but that’s a big trench you would have to dig on each side. A bullet mole tool might be a better option. It doesn’t use water, you hammer it in with the pipe attached. bulletmole.com
If you take out to much around the pipe you cam push in back in with a long pice of wood like a 2x2 . Hit the end of the wood with a hammer to pack it in
Anyone try this with larger diameter 4-6” under a 30” asphalt driveway? Thinking of starting with an 8” auger from the hillside then hammer the pipe in with the pressure washer the rest of the way. Only need a 3” pipe but might as well have room for future.
4” pipe should be plenty. Unless you have some extreme flow of water going through it. Don’t make the hole way bigger Thant the pipe it should be tight agents the soil. You might get cracks in the asphalt because the pipe isn’t supporting the soils. If you use an auger use a 4”. Good luck with you project.
It’s possible. Be careful hitting the end of the pvc because it can crack off into sharp pieces and hit you in the face. Use a pice of wood against the pipe and hit the wood with the hammer. Also if you have a cap on the pipe it would make it hard to hammer through and if you don’t have a cap it will fill with dirt and need to be rinsed out with water. They do make a tool called a bullet mole that’s made for this. Check it out bulletmole.com
I was told that you should fill in the area around the pipe after setting it with a product similar to right stuff spray foam that you can use with dirt so that you have no cavity under the walk to prevent the sidewalk from cracking. Are you aware of such a product and do you know the proper name and manufactor of it?
How wide is the concrete slab? I would just run a new water pipe under the slab and cut out the old section of pipe. Then reconnect both ends to the new pipe. You can use the method I showed in the video.
Demonstrates his jet nozzle as his garden plants scream silently in fear. Oh, my bad, I guess he's using that to run more pipe. That's makes more sense.
Try your best not to under min the walkway. If you do you just have to pack it back in with with your hands and tamp it with a thick pice of wood and a hammer.
I’ve hammers pipes in before. I thought about buying a bullet mole but wanted the video to be helpful to everyone on a budget. In the future I can revisit this video and add these in.
@@TheUltimateHandymanKyle some people have access to a Tool Library, so cost is not an issue. But they have to know to ask the tool library for the Bulletmole.
Great stuff but when all the fails, I’ve had to resort to using oversized electrical conduit, crimped to a sharp point and a sledge hammer, then using the metal conduit as a conduit for the pvc.
Dynamite is want you need😂. How far are you running the pipe? You could try using the power washer method. Drive a bigger pipe under the walkway and wash out the clay with the washer. Then run whatever size pipe through your conduit pipe. Let me know how it goes
