InterDam & Promat: A collaborative milestone in tunnel safety

InterDam is a major supplier of blast and passive fire protection products for the global industry, principally walls, doors and window systems. InterDam has experience of providing products in fire resistant classes according to international tunnel Standards RWS / HCM / ISO 834. InterDam is well versed in the key difference between tunnel doors and most other types of fire resistant doors: Tunnel doors are escape doors and are only used in case of an emergency. Rigorous testing, use of the best materials, proper dimensioning of all materials and regular maintenance assures the door functions as specified. Get the people to safety and keep the fire out. Always. Guaranteed.

InterDam is delivering primary safety for travelers in several tunnels in the Netherlands, Belgium and the USA. These doors are engineered to withstand extreme conditions, proven by rigorous testing against the RWS (Rijkswaterstaat) fire curve which peaks at 1350°C. Additionally, with an emphasis on accessibility, the doors are designed to be easily operable by anyone, requiring less than 100 N of force to open in case of an emergency.

Promat, a key partner in this project supplies InterDam its intumescent seals and calcium silicate boards. These easy to install intumescent seals (known as PROMASEAL®) are designed to expand multiple times and build up pressure in the event of a fire, effectively sealing off fire and smoke paths to secure evacuation routes. With over 30 years of aging and humidity resistance, these seals ensure long-term durability and reliability. Promat also supplies its PROMATECT® calcium silicate boards. These products are engineered to prevent heat transfer and maintain structural stability even after a fire, guaranteeing the tunnel's resilience in extreme conditions.

Promat's products are fully RWS compliant, having been tested for high temperatures over a long duration, proving their reliability for the tunnel's challenging conditions. Promat's deep expertise and close collaboration with InterDam ensure their fire protection solutions are seamlessly integrated into the tunnel project.

Both companies aim to create the best possible solutions for safety and protection! With the highest quality products and a high level of expertise. To make this happen, they search for the most valuable connections and best products to use.

Thanks to these shared values both companies are very happy with this co-operation and will gladly continue to collaborate into the foreseeable future.
