Hi,
I have a ditch in the front yard that collects runoff and diverts it into a 12" concrete pipe that runs under the end of the driveway. It is probably about 30 years old. A man came out to look at an unrelated project, and looked at the pipe and said that it looked uneven or broken in the middle, but not to worry about it and to just fix it when I had to fix it. When the water flow is heavy water does flow out of the other end of the pipe.
I was wondering if there was some sort of sealing technique that was available, rather than digging up the driveway and replacing the pipe.
Thanks,
itchy
