Geosynthetics for Precipitate Clogging
April 1st, 2023
Q: We are retrofitting a highway edge drain where rubberized concrete was used as the base course layer. What type of geotextile or geosynthetic should we consider for this project’s drain? A: Clogging of geotextiles, geonets, geopipe and/or geocomposites is a challenging design for certain soil types or unusual situations. This is one of them. […]
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 […]
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 […]
Landfill trenches with geocomposites

Solmax pit thermal energy storage with geosynthetics on the Tibetan Plateau
July 19th, 2021
Photograph courtesy of Solmax Tibet has an average elevation of more than 13,100 feet (4,000 m), reaching to 16,400 feet (5,000 m). At these heights, temperatures can remain below freezing all day in winter, plunging to –4°F (–20 °C). In 2018, Tibet’s first large solar thermal district heating system was designed and built at 15,000 […]
