Geosynthetics in green roofs
August 1st, 2022
To talk about geosynthetics on green rooftops is to talk about an opportunity to change and make an environmental improvement in the world. The growing need to create awareness of an ecological responsibility and the environment has allowed this concept to spread more successfully. FIGURE 1 8,611 square foot (800 m2) extensive green roof central […]
Landfill trenches with geocomposites
June 1st, 2022
Q: I am wondering if you know of or can point me in the right direction in regard to determining viability of leachate disposal via spraying back onto the active face of a landfill. I have a landfill that has a few issues, and while, from a practical sense, we have had some success with […]
Multi-linear drainage geocomposites for railways
June 1st, 2022
FIGURE 1 Multi-linear drainage geocomposite under railway embankment In civil engineering, drainage systems are traditionally made with granular material layers and perforated collector pipes. The use of drainage geocomposites became more common 30 years ago with the development of products that met the specific requirements of each application. Moreover, the geocomposite is cheaper than the […]
ABS geosynthetics product types
February 1st, 2022
Q: Infrequently, I make a note of geosynthetic products manufactured using acrylonitrile butadiene styrene (ABS) (e.g., geogrid, binding line, a few molded specialty products). Can you provide a summary of most of the geosynthetic product types using ABS, as well as the general benefits and limitations of ABS geosynthetics? A: Thank you for your GMA […]
