Скачать или смотреть OPERATION DRY BASEMENT -- Foundation Secrets From the Era of Fortifications

Before modern waterproofing, ancient and early-modern engineers fought a constant enemy: water infiltrating fortress foundations. Under the codename “Operation Dry Basement,” this video uncovers the ingenious techniques used to keep castles, bastions, and fortifications dry, stable, and battle-ready.

From stone-layering strategies to hidden drainage tunnels, anti-seepage chambers, layered gravel beds, and complex groundworks, you’ll see how military engineers designed structures to survive floods, storms, and siege conditions. Many of these forgotten solutions still influence modern foundation engineering today.

Explore the surprising overlap between fortress construction and today’s basement waterproofing industry — and discover how centuries-old design secrets continue to protect homes and strongholds alike.
