Moderated by George R. Koerner and Y. “Grace” Hsuan DARCIAN PERMEABILITY Q: I am aware of the section in your book regarding geomembrane “permeability” and get from it that it aims to calculate an equivalent Darcian permeability using vapor diffusion via Fick’s law. Can one use the derived permeability then when calculating flow using Darcy’s […]
Automation of large-scale geotextile and geomembrane fabrication
October 1st, 2018
The development of a large-scale fabrication machine was conceived during the fabrication of geotextiles for a tailings pond cap in 2010. The machine joins five strips of material at a time to create fabricated panels for large projects. It is capable of both welding geomembranes and sewing high-strength geotextiles. This machine was specifically designed to […]
