Our standard residential bunkers are typically buried 3–6 feet (0.9–1.8 m) below ground, offering solid protection from natural disasters and surface-level threats. For heightened safety, we also offer depths up to 10 feet (3 m) or more, depending on site feasibility and engineering specifications.
Our bunkers are constructed using reinforced concrete panels, steel linings, and shock-resistant seals. They protect well against conventional blasts and near-miss impacts, but are not built to endure direct hits from bunker-buster missiles. Military-grade installations requiring such defense levels need specialized designs—contact our engineering team for tailored solutions.
Storage capacities vary by bunker size and layout:
Roughly 100 sq ft can hold about 600–800 person-days of dried or freeze-dried food. For instance, a 200 sq ft bunker can store over 120,000–160,000 calories per person per month, sufficient for 20–30 days.
We also offer modular shelving and sealable containers to optimize storage efficiency.
Yes, our bunkers are designed for autonomous operation:
Manual systems for water pumps and lighting
Built to integrate solar panels, battery-backed generators, and off-grid hybrid systems like microgrids or standalone power units.
Essential systems (lighting, air filtration) have manual or battery backups.
However, long-term habitation still requires periodic resupply of batteries, fuel, and consumables.
Our bunkers feature HEPA-grade air filtration and optional overpressure systems to block contaminants. Ventilation runs via passive ducts or battery-powered fans, with manual override options to ensure airflow even during power loss. Regular maintenance and filter replacements are crucial, and we provide service schedules and training.
We offer on-site storage tanks (300–1000 L), gravity-fed or manual pump systems, and gravity-driven filtration. For a 5-year habitation scenario, you’d need at least 1,800 US gallons (~6,800 L) of water . Sanitation solutions include chemical toilets or composting units, alongside septic or sealed-waste systems tailored to your bunker size and usage.
