Roxtec cable and pipe seals provide certified protection against multiple risks. Use them to secure defense bunkers and bomb shelters from blast load, fire, gas, water, and EMI/EMP.
Developed to protect life and keep critical infrastructure functioning under extreme conditions, our fire rated transit seals are ideal for bunkers and shelters – where failure is not an option. The seals are designed to comply with military and toxicity standards and to secure post-impact functionality. Besides blast, fire and flooding resistance, you can ensure:
- EMI/EMP shielding
- Gas and smoke tightness
- Ex rated protection
- Pressure resistance
- Chemical resistance
- Pest and rodent barrier
Protecting the survival system equipment
Bunkers are so much more than shelters with thick reinforced concrete walls. They can house military command centers, data centers, power generation systems, water and air filtration, or medical or logistics functions. All those survival systems must always work – regardless of missile strikes, shockwaves, extreme heat, and chemical threats. This demands continuous electricity, data transmission and water and air circulation, and that is why it is extremely important to seal all openings for cables and pipes with military cable transits and blast seals:
- Decontamination areas, overpressure zones, and air filtration systems
- Entry points for power cables, communication cables and water pipes
- Boundaries between fire compartments and zones inside the bunker
- Critical command, control and battery rooms inside the bunker
- Vertical shafts, ducts, utility tunnels, and horizontal technical corridors
- Redundant systems for power and communication as well as escape routes
Ensuring safe long-term bunker operations
Roxtec penetration seals offer further advantages. They are engineered to simplify everything from design and installation through to retrofit projects and future expansion. They are space efficient to allow for high cable density – all while being easy to inspect and maintain.
Easy to install in existing and new bomb shelters
Roxtec provides certified penetration solutions supporting both new construction and modernization of civil defense shelters.
- In renovation projects, Roxtec sleeves can be installed in a drilled and backfilled opening, enabling the later installation of Roxtec seals during cable routing.
- In new construction projects, Roxtec sleeves are integrated during concrete casting, with Roxtec seals installed during cable routing.
Are Roxtec seals certified for military applications?
Roxtec cable and pipe seals provide certified protection against multiple risks in line with strict military standards. Therefore, our seals are frequently used to increase safety in defense test facilities and test ranges and ammunition depots, missile storage facilities, and warhead magazines as well as in sensitive compartmented information facilities (SCIFs) and shielded facilities.
