We have a downspout that runs down the corner of our garage and empties onto the sidewalk which come to the garage wall. I would like to run the downspout down through the sidewalk, under the sidewalk and out into the yard with a bubbler at the end. How do we go about that?
they have devices you can use to bore a tunnel under the sidewalk, but they usually require that you can get down to the level you want for a few feet. But it'd save you structural concerns with the side walk
