Water does not have to be a major obstacle during tunnel construction. Modern concrete lining systems provide superior water resistance that virtually eliminates the maintenance required to repair water spots, dripstones from lime diffusion, and external corrosion. Manufactured from high-grade polyethylene resins, AGRUFlex has flexible mechanical properties, a long service life, an easy installation process, and is non-toxic.

This webinar will introduce viewers to AGRUFlex, exploring the applications that can benefit from a highly elastic concrete protective liner that provides corrosion and water resistance.

During the webinar, viewers will:

  • Learn about the basic properties and advantages of AGRUFlex.
  • Discover how to use innovative installation methods for AGRUFlex and other related tunneling accessory products.
  • Learn about compartmentalization and technologies to assist with any potential future repairs.
  • Have their questions answered during a Q&A.

This webinar will last for approximately 45 minutes with 15 minutes of Q&A.
