The Kverndalen Bridge forms part of the fast train to Norway's airport just outside Oslo. The railway project includes several major bridges, of which Radcon Formula # 7 has been applied to three - to the deck and culvert.

The primary reason for choosing Radcon on these bridge is due to the crack sealing performance of the product. Most concrete sealing products will provide some protection to the structure by safeguarding the general matrix of the concrete however Radcon can address cracks which may be present or develop in the structure. Local testing has been undertaken through SINTEF for chloride ingress and permeability.

By sealing cracks in the concrete as well as the matrix, Radcon's performance is greatly enhanced offering superior protection for concrete exposed to freeze-thaw attack, chloride ingress and other air borne pollutants.

Also a major consideration on this civil project was the extensive use of heavy balustrade (stones) along the rail tracks. Although Radcon is a spray applied liquid it penetrates the concrete without leaving a surface film. The product works by reacting with the free calcium ions within the concrete to form a sub-surface waterproofing barrier. Therefore the placing of heavy balustrade onto the treated concrete does not damage the Radcon treatment.
