Protan InfraPlan is a complete water protection system for tunnels and underground constructions. Benefits include low life-cycle costs, easy installation and environmental gains.
We live in a world that depends on mobility. Tunnels and other underground infrastructure play an important role in a well-functioning society. This critical infrastructure has to continuously tolerate heavy stress and last not just for decades, but centuries.
Water pressure, toxic chemicals and bacteria, gas diffusion, geostatic stress, traffic vibrations, extreme temperature swings, other weather and climate stresses – the list of what underground infrastructure must tolerate is long. This is why it is vital that high-quality materials and protection systems with a long lifetime are used.
Protan has over 80 years of experience in membrane technology. At the same time, we have almost as much experience in supplying recognised products and solutions for membranes used in the ventilation of tunnels and mines. We have combined this competence and market knowledge to create a sustainable and highly durable water protection system for all types of tunnels.
Protan Infraplan was launched in 2021 and is designed to be functional and versatile. This sustainable, homogenous, flexible and watertight single-layer membrane is made to last.
Protan’s tunnel membrane has been well established in the Turkish tunnel market for many years, and is, among other applications, widely used in Istanbul’s underground rail system. It meets the requirements of the Norwegian Public Roads Administration handbook and other European requirements.
Protan InfraPlan is easy for companies to use and install. Protan roof membranes are known for their long lifetime and for having the lowest carbon footprint in the industry, and these important values for sustainability and durability also apply to our tunnel membranes.
In addition to protecting the tunnel, Protan tunnel membranes also help to protect the area both inside and surrounding the tunnel by, for example, preventing groundwater pollution and the leakage of oil or chemicals from the tunnel out into nature.
For partial waterproofing the most common tunnel application is the Umbrella System/Drainage System. This system is specifically designed for tunnels with dripping water conditions.
Single Barrier System is for hydrostatic water pressure conditions including compartments and injection possibilities. Double Barrier System is also designed to withstand hydrostatic water pressure and combines a test and injection system.
For tunnels with dripping water conditions, the Norwegian Road Authorities recommend to use a Type lll membrane, a reinforced membrane that will provide strength and stability.
