Passive Fire Protection for Tunnel Construction

Safety is paramount. Trusted. Reliable. Proven.

Life safety is critical for road and rail tunnels and our passive fire protection solution, FireMaster® FireBarrier™ has been successfully leading construction of these tunnels for decades.

Our systems insulate the main concrete structure of road and rail tunnels to prevent collapse in a fire and to also provide fire insulation to escape passages, refuges, ventilation shafts and critical communication or fire fighting services.

Tunnel Fire Protection

Spray Application Solution

FireMaster FireBarrier 135

FireMaster FireBarrier 135 is a spay-applied fire protection system offering good bonding strength to concrete and steel substrates providing a strong, smooth, surface finish with high quality appearance. Our fire protection solutions are tested and certified for all major fire scenarios for Tunnels and as well as 20+ years proven performance references.

  • High quality surface finish that may be used as the lining surface
  • High strength with high adhesion strength typically 8 times its weight, allowing fixings to be attached directly to it and like concrete, strength increases over time
  • Ease of installation with virtually no wastage due to spray rebound and may be formed into boards or shapes where spraying is not convenient

Why FireBarrier 135 for Tunnel Fire Protection?

Product Application Features

Unlike most other products used for tunnel fire protection, FireBarrier 135 is a refractory material able to withstand repeated and prolonged exposure to high-temperature exposure.

  • Refractory Product - can withstand repeated exposure to 1350°C for long cycle times
  • Very low spraying wastage during installation - less than 1% of weight
  • Fast and easy to install - one, single-layer application
  • High adhesion strength - eight times greater than product weight
  • High-quality surface finish that can be painted

Optimal Performance in Fire Tests

Proven and Tested Performance

FireBarrier 135 is one of the most extensively fire-tested products available for tunnel fire protection with numerous tests to the various fire standards in force.

  • Numerous tests have been carried out to the RWS and HCM high-temperature tunnel fires
  • In these tests FireBarrier is required to insulate the concrete substrate to below 380°C and reinforcement bars inside to below 250°C (25mm from the concrete surface)
  • Some tests have even lower maximum temperatures allowed for the concrete as spalling temperatures vary for different concrete grades
