How to Install Outdoor Stereo Speakers in Your Garden

The easiest way to make a hole under concrete, such as a walkway is to hook a garden hose to the end of a 4’-6’ piece of pipe and use the water pressure to drill a hole. A sweeper nozzle on the end of the pipe to focus the spray also helps. The idea is to have the water pressure rinse away enough soil to push the pipe through. Depending on your soil, a combination of water pressure and brute force will bore a hole under a sidewalk or other concrete structure.
