ARCA IS PROTECTION
A multi-section protective shelter will allow students, employees and passers-by to always stay close and safe.
Durable material: Made of high-quality reinforced concrete, the shelter provides maximum reliability and durability.
Increased explosion resistance: A special polymer coating significantly increases the explosion resistance of the structure. ARCA can be used as all types of civil defense protective structures (storage, PRU, SPP, PMU and others). ARCA fortification structures are multi-section multipurpose shelters for civil and military purposes. They are designed by highly qualified specialists and have passed field and physical tests at the State Research Institute of Building Structures in Kyiv. Withstands excessive air shock wave pressure over 300 kPa. They have reinforced reinforcement with reinforcement with a diameter of up to 18 mm, reinforcing meshes that are arranged with an offset so that the intersection of one mesh is opposite the holes of the other mesh; internal concrete composition of appropriate strength; metal fiber filler.
Protection class: A-II A-III, A-IV. Withstands excessive air shock wave pressure of over 300 kPa. Radiation exposure can be reduced to Kz = 5000.

BUNKER-OK is a Ukrainian engineering brand providing modern shelters and civil defense solutions for the private sector, business, and civil and strategic infrastructure.
We design and manufacture protective structures, systematically improving them based on practical operational experience, analysis of shelling consequences, and the actual behavior of structures during combat strikes.
Drawing on the experience of over 400 installed shelters, the BUNKER-OK team has reached an unequivocal conclusion: not every structure that looks like a shelter is capable of providing the proper level of protection.
We have studied actual destruction and structural weaknesses of low-quality installations, and we responsibly state: effective protection is determined not by the volume of concrete, but by structural integrity and a well-engineered reinforcing cage that stops shrapnel, localizes impact damage, and saves lives.
That is why the BUNKER-OK team is the first in Ukraine to establish CPS (Civil Protection Standard) — a next-generation quality standard.
CPS was created based on physical loads, engineering expertise, and field testing against modern combat threats, including:
- 120 mm OF-843 mortar shell
- 125 mm OF A-IX-2 tank shell
- HE-Frag warhead of the Shahed-136 strike UAV (47.8 kg)
In today's reality, the legally established testing standard of 2 kg of explosives (TNT) is increasingly becoming just a basic regulatory threshold. It rarely corresponds to the scale of modern threats, cannot be considered a comprehensive indicator of protection, and is not a convincing basis for evaluating a shelter's reliability.
The CPS quality standard by BUNKER-OK significantly exceeds current state requirements and sets a new safety benchmark for the market.
We are convinced: the CPS quality standard must become the fundamental basis of choice for every buyer and a new benchmark of quality for every shelter manufacturer.
BUNKER-OK is not just a manufacturer.
We are a company shaping a new culture of protection in Ukraine and worldwide.
