With cut and cover tunnels, as with other structures, a long and safe service life is a high priority and is influenced by the design of the drainage system. The installation of geocomposites at tunnel projects is a proven method to drain off water safely and protect the tunnel sealing system.

For the use in tunneling, the Enkadrain product range offers a number of proven and tested drainage mats. Enkadrain can be installed quickly and easily over large areas and be adapted to the most complex geometries. For many years now, different types of Enkadrain have been proving their capabilities in terms of runoff capacity, compression resistance and protection in tunnels and galleries all over the world. Many studies composed by independent organizations endorse Enkadrain’s performance in cut and cover tunnels. Colbond's broad product range allows to always offer the right Enkadrain product type best suiting the project specific requirements.
