How to bore under a sidewalk fast and cheap

[@beverlyfraser4080]

I have been thinking about doing this for weeks….then your video popped into my feed. I got up and went to work right away. My project is complete….successful drip line installed under 2 feet of sidewalk! Thanks for the inspiration.

[@helpmylandscaping]

Wow! That is so great! You have inspired me to keep sharing landscaping tips. I really appreciate your story. You just made my day. 😃

[@jjjohn5914]

thanks ...very well done...have u tried this method under a driveway?

[@helpmylandscaping]

I have tried this method on a driveway. But I substituted the black poly for something more rigid like Sch40 PVC. You can get 10 or 20 foot lengths. The connections should be glued too. And because it is more rigid, the trench on the starting side needs to be longer.

[@bradlandon7950]

Would this method work for 3 inch drain pipe. Don't know how you would connect the hose for that application.

[@helpmylandscaping]

Using a 3 inch drain to push underneath a sidewalk using water in it would require a massive amount of water pressure. For that scenario I might recommend using this 1” pipe method, except instead of leaving it, you could pull it back out and bore underneath it again near the original tunnel. You may have to do this a few times. Or try it with a PVC sch40 pipe and do it a few times. Then when the area is opened up more, use an extra section of 3” drain pipe to push through (using it to push in and pull out some dirt- several times). Once through, you could remove it and install the permanent pipe.

Yes it has been helpful. Thank you.

[@rl945]

Great idea

[@helpmylandscaping]

Thanks!

[@prince027]

Great and useful video. Thanks.

[@helpmylandscaping]

Thank you! I love doing it.

[@sks1024]

did this with my sprinkler installation years ago.

[@helpmylandscaping]

It works most of the time. Wish I knew this a long time ago

[@josephbridges7667]

Exactly what I needed for my foundation drip line I have running around my house

[@helpmylandscaping]

If you need other tips or have other questions, just let me know.

[@helpmylandscaping]

I have another channel that is just for irrigation. It’s @practicalsprinkleradvice might have some other ideas too.

[@bcboncs]

Nice video. Is the water pressure enough from the hose though? Seems like a weak jet, no?

[@helpmylandscaping]

The pressure is usually good enough from a hose. It’s also the shape of the fitting that helps and the volume of water helps to push stuff out of the way. You could use a shorter garden hose to reduce pressure loss

Very slick!!!

😎👍🏼

[@joshuatran3667]

All soil and no rocks? Nice.

[@helpmylandscaping]

This particular sidewalk was a dream. There is an advantage to going just below the sidewalk. It’s usually backfill so the rocks are smaller and less roots.

[@burntblonde2925]

If you’re using flexible tubing, isn’t it better to use conduit or something wider, in case you need to replace the flexible hose? Then draw a map. With measurements, so you know where it is?

[@helpmylandscaping]

I always recommend taking pictures of any project. Sometimes I include a tape measure in the photo. Also, an “as built” drawing helps. Regarding the flex vs rigid pipe- you can use either. The advantage to the flexible pipe is that you don’t have to dig as long of a trench to install it. With rigid pipe and a short trench, the pipe tends to angle downward. Which is okay for narrow sidewalks, but for wider areas can get quite deep. If you plan on replacing the pipe/hose later, I would recommend using a larger pipe to bore under and then leave it. That way you can slide the smaller diameter pipe through it later. Hope this helps.

Do u have a link to the exact end funny Pipe fitting used? Thanks!!!!

[@helpmylandscaping]

I get my parts through a wholesaler, but here are a couple links. Prices fluctuate often. www.dbcirrigation.com/buy/product/sw1429-129-1x3-8-swing-pipe-ins-coupling-100sw/465?text=1%22+poly+insert+x+3/8 www.sprinklerwarehouse.com/poly-insert-spiral-barb-coupling-1-in-x-3-8-in-insert-x-spiral-barb

[@sergiovargas7079]

Thanks man

[@helpmylandscaping]

👍🏼

[@michaelbyrd9869]

I cannot find the "end fitting" that the water shoots out of anywhere. Can anyone point me in the right direction?

[@helpmylandscaping]

I found one. It is Spears part no. 1429-129. Here is a link to Amazon. You might be able to find it other places too. amzn.to/4bVvgZZ

Easy on clean good quality soil. The clay we have here would laugh at your idea.

[@helpmylandscaping]

True. It works most of the time. But I have struggled with some sidewalks.

[@buddyboy4x44]

Cheap enough to try first, then ramp it up if it does not work.

[@helpmylandscaping]

True. It does help, and I forgot to mention this, often the poly pipe has a slight curve to it. So if you put the curve facing up(towards the concrete) and the clamps on the bottom side, it helps guide along the bottom of the sidewalk, and the clamps don’t get hung up as much.

[@poprocks315]

You shouldnt have clay at this depth under your walkway.

[@Simonsimon-fy3hq]

That's why we don't have walkways.@@poprocks315
