The company said that the tunnelling industry would now become a key focus of its efforts, with production taking place at the newly-acquired facility in Istanbul.

Protan is an innovative force in many different business areas, providing environmental-friendly and high-quality solutions in roofing, wet rooms and fish-farming, and we look forward to unlock the same innovative forces with our own production line for tunnel membranes.”
