View Full Version : Best way under sidewalks

This may seem a pretty silly question but I'd like to hear about some techniques for running irrigation lines under multiple sidewalks. I have an RFP on a larger commercial that will require crossing under dozens of existing sidewalks. Our company is not yet prepared to do this many sidewalk crossings efficiently.(is there a machine we should buy or rent?) The soil texture is anywhere from sandy loam to clay and this is causing an issue on bidding this property properly. The sidewalks are no greater than three-four feet in width. Pipe size would be 1.5 inch at most. Any suggestions would be appreciated. Thank You.

Both the Ditch Witch 255 and 410 have attachments on the front for boring rods. They work really well, and if the sidewalk isn't wide as is the case for you, you don't have too worry much about keeping the rod perfectly horizontal which takes some practive to get right.

You could check with a local rental company
on a boring machine or check out http://www.sidewalksleever.com
I have a boring setup on my trencher but sometimes it is a pain loading up the trencher just to bore under a 4' sidewalk, so I made two sidewalksleevers and they both work very well.. we did a 8' sidewalk a couple of weeks ago.

I'm looking very seriously at a bor-it (http://www.borit.com/index.cfm) for this season. I wish I had 255 or 410, but around here, we all use 100sx's.. so no take off for boring.

I have a condo site where I need to go under 20 or 30 spots, and the soil is so compacted that it takes 20-30 minutes just to pound a bar through, so I'm hoping that this thing will pay for itself.

There might still be some boring machines that are kind of like a posthole digger laid on its side. A small wheeled platform with a horizontal gas engine and gear reduction. Water assist for wet boring, if wanted.

Wunderunder is popular down here. I always get the side walks with a mess of constuction debris piled under them.

We have a borit...soil conditions very important...correct on the wunderunder,
got half-way under a driveway & hit mess of old bricks! Ended up running the
main & wire all the way around the site! Will contractors ever give us sleeves, or even ask?

What kind of conditions are important for the borit? I've got a lot of compacted clay and gravel under the walks....

Also..any links to the wunderunder?

Ones crosses their fingers & everything else when you make a punch.
Go slow, give yourself plenty of room for water, prepare to junk the 1/2"
drill after a few punches...water + electricity= danger!!!!

Was wondering about the water + electricity combo.

I wonder if a cordless could put out the torque required....

We couldn't get anybody to bore under a 22" driveway so a friend brought over a Vermeer Mole. This is a torpeda looking device (2 ft long 1 1/2" dia)driven by a large compressor. It went right under the drive way. It has a jackhammer sound to it and it walk along under the concrete dragging the air line. It went through straight as an arrow-fortunately for us.

Mole or missiles are the only ticket . I know of a mechanic that has 3 for sale. ( I posted them in a earlier post )

I personally have 3 , tow, two and a half and 3 and a half . They are great for walks , and drives. I also go under landscape beds , narrow areas the machine wont fit . But they are great for adding zones , I use to have to locate pipes and dig around them , now I shoot under them .

I paid for them on other jobs besides my own , once the word got out I have plumbers and electricians I make shots for regulary , at 15.00 a foot plus our hourly rate

How pricey...we don't own a backhoe, but we do have a 125 compressor.

Well I know that a rebuilt one cost $1500....after reading some of the post on here about the mole I don't know if I could afford to have one since there is some risk that it will just disappear under the ground.

Might be this wonderful but DRY weather. About .5" total for March here, not counting today. I couldn't wait for winter to be over.............I haven't got the days counted til Nov. but I'm starting to wonder already. One hundred hour weeks are good for the soul........or something like that. Unfortunately, I'm not that young anymore. (but I'm not actually putting in 100/wk yet either, only about 12-15/day)

I tried the boring rods and homemade sidewalk sleevers and the problem is the boring rods are not made of a steel that can be continuously hit with a sledge hammer.they started to bend on the first installation. I own two Sidewalk sleever and they are worth every penny.

Getting back on subject, every technique has it's place and it uses when the need to bore underneath concrete.

What nobody really talks about is the preparation needed to do the shot it the first place.

For example, in most of the work that I do in the valley, the good ol fashion water pressure trick does the job. Get in the mountains of San Mateo County, due to clay\rock combo, it takes me more time to prep for the shot than it takes to do the shot itself. Also, this is where I will consider using my borit tool.

There are so many techniques, but every techniques has its place. The draw back is every technique has a different labor element involved.

We did a 8' sleeve a couple of weeks ago using a 16lbs sledge hammer....Here is a pic of the ends, one is a trailer ball:hammerhead:

Looks good but also like a lot of work. I guess you need the time and the equipment to make those. It was sure quick to just buy one.
