Part 2 of our DIY Underground Bunker Build is here! 🏗️ We’re removing the formwork, installing a double-layer rebar mesh, and pouring the final reinforced concrete walls. Then it’s time for waterproofing prep, natural stone detailing at the entrance, and leveling the interior floor — turning this from a simple basement into a real underground bunker shelter.
This video shows every step of the concrete wall construction process: how we set rebar for strength, align formwork, pour thick reinforced walls, and tie the structure together for long-term durability. Perfect for anyone searching for DIY bunker ideas, basement wall construction tips, or off-grid shelter builds.
