Reviving the Palos Verdes Reservoir, Part 3
February 1st, 2019
California’s water infrastructure is one of the most challenged systems in the United States due to the large population it supports, the age of much of the water infrastructure, and the diverse environments—mountains, coastlines, old-growth forests, deserts—found in the state. The water infrastructure is also one of the country’s most advanced systems, in part due […]
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 […]
