US-Mexico Border Wall Construction： The Hidden 95%. Mega Construction Projects

How is a border wall actually built across desert, mountains, rivers, and extreme slopes? This documentary follows the engineering behind the US-Mexico border corridor, from trenching and continuous concrete foundations to 30-foot steel panels, robotic fabrication, night installation, concrete-filled bollards, patrol roads, lighting, fiber-optic sensors, thermal cameras, and microwave communications. See how crews coordinate multiple work fronts, move massive panels into tight tolerances, and tackle grades steep enough to challenge normal construction equipment. By the end, the visible wall is revealed as only a small part of a much larger infrastructure system built above ground, underground, and behind the barrier. It is a close look at the machines, logistics, foundations, and surveillance technology behind the project.
