What is the best way to drill a hole under a sidewalk?

1. Using a hand drill

2. Hammer and pipe

3. Electric drill with extension

4. Garden auger

The correct answer is: Hammer and pipe

Using a hammer and pipe is the best method for drilling a hole under a sidewalk because it allows for effective penetration into the soil without damaging the sidewalk itself. This technique involves taking a sturdy pipe that can be driven into the ground, and using a hammer to apply force to drive the pipe beneath the sidewalk. As the pipe enters the ground, it creates a channel that can be used for various purposes, such as laying irrigation lines or other utilities. This method is particularly effective because it's simple, requires minimal equipment, and can be done in relatively confined spaces. The use of a hammer gives the operator control over the force used, reducing the risk of damaging the surrounding area while providing enough power to penetrate hard soil. It's also a technique commonly recommended for its practicality in landscaping and construction tasks requiring access beneath sidewalks or driveways. Other methods, while feasible, may not provide the same efficiency or level of control needed for this specific task.
