Kanai Resort shoreline protection and beach creation
February 1st, 2021
The completed Kanai Resort shoreline. Photograph courtesy of TenCate Geosynthetics. The Kanai Resort shoreline protection project had three distinct phases utilizing sand-colored geotextile tubes. The first phase was to install a natural-appearing shoreline protection structure with a height of 8.2 feet (2.5 m) to protect the entire 1 mile (1.7 km) of the resort shoreline. […]
Innovative geosynthetic solution saves 106-year-old Panama Canal structures
August 1st, 2020
By Tom Stephens and Nicolas Ruiz FIGURE 1 Preparing to place a 65-cubic-yard (50-m3) geotextile bag container into 66 feet (20 m) of water at the Gatun Locks dividing wall The Panama Canal opened for business 106 years ago and was hailed as the eighth wonder of the world and an engineering marvel. It has […]
The GMA Techline
August 1st, 2020
Seaming dissimilar geomembranes Q: I kindly request your technical support in the questions below: A nonpolyethylene geomembrane was used in phase 1 of the tailings dam waterproofing system of a gold mine. For the expansion (phase 2), the use of a high-density polyethylene (HDPE) geomembrane is being evaluated. How can the HDPE geomembrane join the bituminous […]

Geosynthetics are uniquely suited
October 1st, 2019
Geosynthetics are found in the strangest of places. But that just speaks to how versatile and useful they are for a wide variety of applications. Dewatering, energy-site closure, erosion control, reinforcement and stabilization are just a few applications that geosynthetics address in this issue. In addition, many of the geographic areas discussed here are sensitive […]
Reinforcing dunes and bluffs with geosynthetics
October 1st, 2019
By Brian Maggi, Christopher D. P. Baxter, Aaron Bradshaw, Annette Grilli and Naser Al Naser The devastating effects of recent hurricanes and nor’easters highlight the need to improve the resilience of coastal communities. There is a trend toward implementing “soft” engineering solutions such as dunes reinforced with geotextile sand containers (GSCs) or coastal bluffs stabilized […]
Recovery of rare earth elements from acid mine drainage using geotextile tubes
October 1st, 2019
By Tom Stephens Acid mine drainage (AMD) has been occurring in the Appalachian region since coal mining began in the early 18th century. Over time, many mines reached the end of their useful life and production ceased or companies went out of business, resulting in AMD discharging from these abandoned mines into native streams and […]

Multilinear drainage geocomposites to filter oil sands tailing slurries
October 1st, 2018
Mining and some energy operations generate large quantities of water-containing tailings. These tailings are made of crushed-rock particles that are deposited in a slurry form. This is the case for coal, tar sand, lead, zinc, gold, silver, copper, molybdenum, nickel, taconite (iron), phosphate, bauxite (aluminum oxide), uranium, trona (soda ash) and potash, for example. There […]
