AGRU

Company Details

At AGRU we have been producing plastic liners by means of flat film extrusion with a downstream calender to the highest quality standards for more than 30 years. Our Lining Systems product group offers a comprehensive range of geomembranes made of PE, FPP and FPO. The versatility and quality of the materials we use means that we can tailor solutions to meet customer needs in cooperation with the customer.

VLDPE is used globally for lining tunnels today. This prevents groundwater entering the tunnel. Besides the loads that occur including rock settling and shifting, aggressive rock water must always be anticipated. Tunnel liners are thus exposed to high mechanical and chemical stress, and specially designed by AGRU for the use in tunnels. Because VLDPE does not contain diffusing plasticisers, the liner’s optimum properties of flexibility and high tear resistance do not change throughout the liner’s entire service life.

All tunnel liners are made with a thin white signal layer which is affixed in a coextrusion process. This can indicate damage during installation, because the black carrier layer is revealed. And the white signal layer improves safety substantially in the tunnel by reflecting existing light and thus improving the illumination in the tunnel.

AGRU’s state-of-the-art production equipment is capable of extruding VLDPE tunnel liners in up to 4 m widths. They can be fleece backed for special applications. It is also possible to equip tunnel liners with electrically conductive layers for leak monitoring.
