ARCA SPACE is one of the most technologically advanced shelters in Ukraine

ARCA shelters:

• have been successfully battle-tested against the explosion of a Shahed-136 strike UAV warhead (47.8 kg), verified by official test protocols;
• feature a lab-tested 10-fold safety margin;
• comply with the highest protection class in Ukraine: A-I+;
• withstand blast overpressure exceeding 500 (1300) kPa;
• comply with Anti-Radiation Shelter (ARS) classes P-4, P-5, and P-6 in above-ground execution;
• comply with ARS classes P-1, P-2, and P-3 in above-ground execution with earth berming, or in buried and underground executions;
• are engineered for modern civil defense scenarios and critical threats.

Engineering Technologies of ARCA SPACE

TriCore Armor

A continuous three-tier reinforcing cage that:

• increases structural integrity;
• reduces the risk of progressive collapse;
• preserves geometric stability;
• helps maintain airtightness even under partial damage.

Dual Armor

An enhanced dual reinforcement area system for:

• superior distribution of explosive loads;
• reduction of local failure risks;
• containment of fragmentation damage;
• minimization of crack formation.

Blast Comfort

An anti-explosion valve that:

• dampens the blast wave;
• reduces overpressure;
• increases the safety and comfort of people inside the shelter.

BlastLock (Optional)

Reinforced protective doors with a reinforced concrete core to:

• provide additional protection against fragmentation;
• strengthen the resistance of the entrance group;
• maintain the shelter's protective perimeter.

Primary Purpose of ARCA SPACE 4.0

Public Safety: shelter solutions for schools, kindergartens, universities, hospitals, parks, playgrounds, transport infrastructure, and crowded public areas.

Business Continuity: solutions for offices, manufacturing plants, logistics centers, warehouses, the agricultural sector, pharmaceuticals, and commercial properties.

Infrastructure Protection: engineering defence for energy facilities, critical infrastructure, municipal systems, and strategic enterprises.
