    This is some interesting information. I'm wondering if I could do it to make a tunnel for an egress window drainage system. I have no experience in this stuff, but what people tell me is to use a drain tile to carry the water away from the house. I've been trying to think of ways to do that without digging a trench because it would have to be about 5 feet deep and that's too much work. The problem I think I'll run into with this method is that the egress well is only about 3 feet wide, which would only allow me to use 3 feet of pipe for the drilling method. I don't know if that would be a sufficient length to install the tile. Could you offer any suggestions? Do I even need to use drain tile or is there something else I can do.

    Okay, my mom is home owners of a neighborhood. We don't have much money or income. And we need to replace electrical wiring under ground due to a mistake by verizon, they cut the line and they are not replacing it, because there is no evidence that they did it. The problem is how can we get under the road without stopping people from getting into and out of the neighborhood without being to expensive. Like cheap. If you can figure this situation out, then please email me at

    I wish verizon would just take ownership of making a mistake but, there not, so yeah we need an answer, because we can only have half of the front entrance lit up.

    Is it possible to tunnel under a sidewalk made with pavers that are on compacted gravel over a sandy soil (Florida). The pavers are held in place with cement that was placed along the entire edge of the sidewalk. The walk is about 3' wide. I need to get a drain pipe underneath. Thanks for your help.

      Yes, it's possible.

    Had a question about the chisel method above. It appears the plumber drove the pipe under the sidewalk/patio from the basement being the origin. Is that method also acceptable for electrical feeds between two structures?

      As for electrical, you follow the NEC. It's that simple.....

    Unfortunately NEC says nothing affirming or denying the exit below grade method.

    Hi, I have a plastic gas pipe (poly) which I want to put under my driveway. Do you think the pipe over time will get a lot of stress? Should I use other type of pipes or is it going to work with the astm d2513

    I can imagine that having to be detoured because of construction would be a pain. I can see how boring under the road, or sidewalk is better and causes fewer delays. Would need to find a professional that knows how to do it, and do it right.
