re: Boring a drainage pipe under a driveway

Water jetting will only work if it’s a sandy material. With drainage, you are obviously trying to get larger than a 3/4” pipe. Dig your trench level that you are using to shove the pipe and it will stay fairly level. For larger pipes, use a cap on the end of the pipe and drill a few very small holes in the end. Works better than those nozzle kits imo. I’d saw cut. If you have a brick house with some leftover bricks, saw cut the width of a brick and go back with a brick band. Will look better than a small piece of new concrete.
