Engineering Specifications & Protection Benchmarks

BUNKKER shelters are engineered using advanced protocols derived from military, civil defense, and critical infrastructure protection systems. Our methodology ensures maximum resilience against blast shockwaves, chemical contamination (NBC), biological threats, and infrastructure collapse.

Structural Protection Standards

Our bunkers are built with high-strength military-grade concrete shells, reinforced with internal high-tensile steel frames. Engineering follows Swiss structural norms, the global benchmark for critical infrastructure reliability.

ParameterStandard Specification

Concrete Thickness 60–80 cm Reinforced Concrete

Structural Reinforcement High-tensile steel rebar

Blast Resistance 50–80 psi overpressure

Structural Lifespan100+ Years

Ballistic Resistance (UL 752)

For specialized safe rooms and entry points, we integrate materials rated under the UL 752 ballistic standards, commonly used in government and armored facilities.

UL 752 Level 3: Handgun protection.
UL 752 Level 5: High-powered rifle protection.
UL 752 Level 8: Armor-piercing rifle protection.

Engineering Compliance & Methodology

Civil Defense & Military Synergy

While designed for private estates, BUNKKER infrastructures are engineered using the same technical principles as Civil Defense Command Centers and military protection facilities.

Key Design Principles:

Blast Isolation: Absorption of kinetic energy through structural dampening.
Contamination Control: Total atmospheric isolation.
Structural Resilience: Survivability against secondary debris impact.
