Today we waterproof my underground backyard culvert bunker. Visit https://www.kiwico.com/jerryrig for 50% off your first month of KiwiCo with code JERRYRIG. And huge thanks to KiwiCo for sponsoring this video. Before we can bury my backyard bunker and put the dirt back on top, we have to make sure that the bunker tube itself is water tight. If water gets inside the bunker when it rains.... well... that would not be a good thing.
