Sprayed waterproofing approved for Bane NOR 21 Dec 2017

Tekflex water control membrane applied to tunnel lining

Official approval has been granted for the application of a sprayed water-control membrane product in tunnel projects for Bane NOR, the Norwegian national rail authority. The spayed membrane product, Tekflex, is supplied by Minova and provides a thin flexible, permanent sprayed membrane to control water in tunnels or to provide a reliable repair and refurbishment solution. The Tekflex range includes wet and dry products for use in structural as well as waterproofing tunnelling applications. This includes cement based and resin injection products.

The membrane was chosen by Bane NOR as it has good cohesion to rock surfaces, high tensile strength with high flexibility, is easy to apply using standard equipment, and is non toxic and non flammable.
